North West Rolling Road Day - 21/02/09

In an attempt to keep these on a quarterly(ish) basis, I've arranged the next Rolling Road Day for Saturday 21st February 2009.

Once again, it'll be at Dyno Demon in Neston on the Wirral. Cost will be £35 per car and for that you'll get 3 power runs and 2 colour performance graphs.

This is open to everyone, whether standard or modified. Check the previous threads on here for previous results / comments etc.

Poser!

Well its all very well having it, but the weak link in the equation is me cos i will end up setting it up alllll wrong no doubt

Lol - take it to MotorMech for fitting and Dyno Demon for setting up - job done.

I'll fit it myself, apparently they have self learning or something, be interesting to see if it does!

You do know you have to splice into the ecu don't you?

Yeahhhh, it'll be reet! How hard can it be!

Yes please MABR - nice to see a reasonable break after Yuletide too! Cross fingers that all shall be well for then.

I've just posted a link to this on the 200SX Forum to see if we can resurrect our shootout day from earlier this year.

Now that I know it's running perfectly on low boost, I'll be after a higher power run this time

Count me in!

Excellent news Dave and looks like I'll finally get to meet Matt. Will Willy Chin be putting an appearance in?

I don't think he'd like it, All that noise and strange people. I'll put it to him tonight and see what hey says

You talking about CoupeDave or that rat thing ?

They're very similar actually, and both have lived in a cage in my room

put me down as a possible - would be good to see what difference its made now I've sealed up the two boost leaks and sorted the massive over-fuelling

Good news Nigel - hopefully it didn't cost much this time?

OK just a quick update for this;

On Sunday I went across to Dyno Demon to have a chat with the North West Co-ordinators of the SX 200 Owners Club (SXOC) who were having a Rolling Road Day. Upshot is that we have an opportunity to turn this into a "Shootout Day" for both Clubs.

They've asked for an initial 10 places to fill so if everyone's OK with this then I'll throw down the gauntlet. The last time we tried to organise this, the SXOC had to pull out as it coincided with a Time Attack Weekend (well that was their excuse!)

I still want this day to be for everyone though, not just the big power boys (but it would be great if some more of you could get over / back on the road). So if you have a standard coop and just want a Power Run to see what it's doing, still put your name down; if you're running medium power (@ 300bhp) are you up for the challenge? and if you are running big power, how much will it cost to get you to this?

To give you some insight, average power figures on Sunday ran from 250ish to 350ish so it could be quite a closely fought contest for some of us.

Think I'll brng the coop the unles the civic is suercharged by then hahaha

yep i'll be up for it still

Oh hell yeah, bring it! 130-ish BHP? They'll be bricking it!

Yeh count me in. I got 275bhp on 1.1 bar last time, should be more interesting when I set it higher

am off (for once), might have a look down.

I'm really hoping to make this! If its not mapped by then, I may just come along to watch! But the aim is for the car to go on the rollers!

Did anyone else get a Christmas Card from Dyno Demon's?! Fair play to them!

New Year bump.

what happened with SXOC lot?

Bugger - I'll get back to them now.

they probably remembered you for your record high boost levels last visit

i didnt get a card

This is now advertised on the SXOC site.

Assuming my cars OK, I'll come along, see what the old bus is putting out. Be a good starting point.

I'll be there for the real wheel drive club

I usually make just over 390 on dynodynamics RR's, but just finished a new rebuild and although still a few bits to do, she has the promise to get a bit more I hope you guys are ready for us

And how you will laugh if my cars not set up properly and doesnt make her normal potential

Craig, I think we should consider some prizes for this (Reps/Mods excepted, so just normal members!), I can put some cash in from the SXOC......

TBH, I've considered a 200SX several times and when I was 18, I lost a £100 deposit on an early shaper, so should be good, even if just to see some big power 200's :-)

I'll see what I can get sorted and give you a call.

OK guys as this is now 6 weeks away, can people please confirm their attendance?

Good news is that Dyno Demon have agreed a reduced price of £35 per car. This represents excellent value (IMO) for the service and attention we get.

Top power figures from the SX guys last time they were there was @ 350bhp so if any of our big power guys are available, that'd be great.

I'm not going to be able to give a 100% answer Craig! I don't know what is going to happen between now and Feb 21st

It was actually 397

Well that's still @ 350.

i'll be there

Good news on the price reduction MABR - I'm still definitely planning to attend. I just need to swap chips with cowboy between now & then - and I'll finally find out what mine makes as "standard".

"Your clutch should also be in good condition, there is little or no point in RR'ing a car with the clutch slipping - it will only get worse."

A horrible realisation has hit me, my clutch is not too healthy, it holds (most of the time) but is right at the end of it's travel, even resting my foot on the pedal leds to slip. But near the end of Feb should give me time, and the paydays, to get it sorted. With all the bits and bobs getting sorted this month, a new clutch should see the car near to it's former glory.

Then I just want more power...

Suffice to say, I can't commit yet, but I really do want to make it, never had a RR session before. Call me a roller virgin.

just need to confirm with work i can have the day off but don't see a problem.

Count me in as definite

have you got the postcode for the RR? want to see how far it is.

CH64 3UJ

3 hour drive, might be abit too far for me. when do you need to know by craig?

Thought about joining in earlier but after saying I would the last one and then pulling out last minute I have waited till my car is in one piece.
Room for one more?

Sorry for the delay guys.

@ Johna - I remember your shock last time when you realised how far it was. With regards to notice, places are finite and as the SXOC are also attending I'll have to operate on "first come - first served".

If anyone wishes to join in, please update on the attendance list.

Hi Guys,

Update. Yes, now I'm GTEC1'd, clutch is totally effed. Will be there if I can get it fixed before, but I won't be able to say for definite for a few weeks yet.

You can all laugh now a little problem with my AFM and it seems I've killed my ECU and lost my map etc. So I need to get a new ECU and get myself down south for mapping Joy joy is car modding

Hey Craig, I don't think I will be able to make this. The rallye still doesn't have the engine fitted yet. The car is now with my mechanic friend but there's no guarantees it will be finished even in February so I'd best pull out.

Going to have to pull out myself, unfortunately, after my exhaust fell off yesterday, i've had to fork out for a replacement, so the clutch is very unlikely to get done. Maybe next time.

well things have happened so I can attend now for definate!!

I should be there, my car is being mapped next week by flea, so it will be good to see the results on the rollers.

I am no saying 100% yet as my car will be having fuelling checked next Saturday but can't see any reason why i will not be there.
So baring a really lean run in 8 days, Ill be there.

am going to be follow jeff, dont fancy traveling that far by myself.

mini convoy

Im hoping to be there.Getting belts etc on the 17th.

I'll come in my new motor

What is it?

are we all gonna be having time slots??

<<<

Ahhhh, I see. That would be a mauve Coupe then

i would like time slots too !

Hi guys - I'll get timeslots sorted for people this wekend.

is it to late to put me down guys?

wouldnt of thought so, get ya name down..

Any idea of time slots or how many of the SXOC will be there?

if its ok im a definite.Looking forward to it!

Can't see any reason why not or why 12 would be different/worse than 11 but MABR (organiser) will be able to give the affirmative though if any one dropped out there would be space.

Just looked on the SXOC forum and it looks like they have around 7/8 interested in coming.
I was at Dyno Demon a couple of weeks ago, and Steve is prepared for 30 cars or less, so still plently of room for more!

As has been said - no worries get your name down.

Not getting much chance to get on here at present so quick update; will be speaking to SteA from SXOC tonight about arrangements so will post up timeslots for everyone shortly.

OK, following discussions with Dyno Demon and SteA at SXOC we have decided on the following format;

20 minute timeslots with Fiats and 200SX's alternating on the rollers.

So, start time will be 9.00AM. Please enter your names against your preferred timeslot.

Anyone who wishes to bring non coupé or SX200's will be slotted in at the end - coupés and 200's will have priority on this day.

Both Ste and myself are hoping to make this an Annual Event with a shield / trophy of some description.

Apparantly, most SX200's attending this will be running @ 260bhp so it could be a close bit of competition for those interested.

whats SXOC mean? for time slot just put me next to jeff as i wont be on here tonight.

I won't be making this Craig, I'm down south for my niece's christening.

Interesting to see they have done alternate slots, surely they will have to change the rollers each time?

Well if nobody else is going to get the ball rolling then I may as well get straight in with my first choice slot

Im happy to give my slot up to let someone else in who's posted up earlier.I'll be turning up anyway as i'm only 10 mins away.Feel free to delete me.

Nearly forgot.

OK - can't let the side down - I'm a definite - should be there mid-morning

I only live round the corner so I`ll probably turn up just to see a few nice coops and have a chat with a few of you guys.
I would be tempted to get mine on the rollers but its not well with 1 big crack in the manifold.

Pop me down for the 1:40 p.m. slot matey, although I'm sure I will get a run before then based on previous visits.

P.S. Anyone know what rugby games are on that day!?

Well my manifold has started blowing slightly on start-up!! Is it wise to still run it, after a couple of mins it's fine, would it be just warm it up first????

hello?

You have PM MABR

will do!
I have a spare but doubt I will have the time or the know how to fit it by then!!

Don't worry Nigel - I'll get you slotted in.

Nigel, you're down for 5am

Well, after getting my car mapped by Flea, it was running wonderfully until yesterday when the bloody clutch started slipping. A paddle clutch as well, i cant believe it, yet alone afford it!

May very well have to drop out of this unless i can miraculously get it done.

Will keep you updated but i'm provisionally out.

Probably leave a nice gap for Nigel's car!

Was really looking forward to seing how the old girl would perform post map as well

I think there are only 6 of the SXOC going for definite so there would a place for Nigel.
Edit: If you get it fixed in time even last minute there would be space to run it I think

There is a place in Leeds that does motorsport clutches, im pinning all my hopes on them being able to squeeze me in.
Cheers Jef

fingers crossed.. have you got the website address were you got the clutch from? cheers

I dont have a clutch yet but this place gets good reviews;
http://www.clutch-specialists.co.uk/

I think Ash_p is using one of there fast road clutches, and he's running over 300bhp.

Hopefully they can supply and fit for me

ok, thanks.. take it a coupe is a coupa on their website?

Hmmm, as you know it was slipping a bit on the day you picked it up On the positive side it only started slipping after the remap, likely a symptom of more torque. If you go for a CG clutch then make sure it is the competition clutch as the fast road won't last as long.

what bhp will they take flea? cheers

Leighton, it seemed to be ok, until saturday when i started to get masses of slip in any gear above 3rd.
Its all your fault for making my car run so well!

I have to admit I wasn't expecting it to go as i was told by the previous owner it had just been upgraded to a paddle clutch. Clearly not a very good one.

Its just the timing thats unfortunate as i was really looking forward to getting some figures.

Oh well, easy come, easy go.

@Johna, i also assume its a Fiat coupa on there website!!

Well if you don't manage to get it changed it may still be worth going to the dyno as they run the coupes in 3rd gear. The chances are it won't slip as the rollers don't load the transmission/engine as much as the road, unless it's slipping really bad that is.

Re the CG competition clutch, I think Ash said it was rated to 340lbs/ft.

My graph from last time said they ran it in 4th gear, just for info. Could have been a typo tho

They've always ran mine in 3rd. Anyway, that is not an issue as i am taking my car to C G clutches this afternoon for a replacement clutch. Have gone for the "competition clutch" rated @ 325 torques for £590+vat supplied and fitted.

not a bad, price i will have to buy one soon.. clutch is slipping in 1st and 2nd when i put the foot down.. (only got it replaced last year!) dunno if it has anythng with little boost spike i have got or my greddy is set up wrong.

anyway, did you know that the sxoc is calling the coop an Italian Scrabble?

Dropped the coop off this afternoon at C G Motorsport. Hoping to have it back tomorrow, so with a bit of luck i should still be at Dyno Demon on Saturday to put my Italian Scrabble Wagon on the rollers!

fingers crossed..

link to sxoc- http://www.sxoc.com/vbb/showthread.php?t=388670

sorry guys gonna have to bail from this....coupe is gone!!

Guys n Girls,

We've got a (small) convoy going from the tickled trout on the m6, setting off at 0815 if any of you want to join a few 200's for the drive down from that neck of the woods

Cheers

Steve

Gone!? Gone where!!? Looks like I'm the only representative from North (West) Wales then.

Dave - PM me buddy with a full & frank explanation for this behaviour!!

The punishment for such a crime is surely to connect a treadmill to the dyno and have him run his way through it?!

I'm going to pop along, but just to say hi

I haven't done anything to my car since the last RR session, so it's not worth putting it on the rollers.

According to the SXOC site they have 6 X 200's running on the day and a couple of "others" to be tacked on at the end of the day.

Should still be a good day and some of our members can probably get on the rollers a bit earlier.

My slot is officially 11am but I'm aiming to be there 10am at the latest, so I don't mind swapping about a bit if it makes the day run more smoothly

I will aim to get there a bit earlier, as based on previous meetings the guys at DD push people through quite swiftly.

Has Nigel pulled out?

definitely not - I'm just going to slot in when there's a gap (and when we need to show the 200SX boys what our scrabble-wagons can really do )

Good stuff!

Hoping to be there to watch shame my coop aint finished would of been nice to see the numbers again hahaha and the cool weather may of helped it get a little higher. O well good look to the coops!!

see you all there tomoz boys and girls!

I've got my car back from the clutch shop, it should be bedded in by the time i get there. See you all tomorrow

Check your oil ETC! (as per guide.)

Just done that tonight - including the transaxle (got a few leaks going on down below!). Coupe is cleaned & ready to go - but I have a noise on start up which is concerning me. Bit of a "chiruping" noise - which goes away after a bit. Have had the odd misfire too - but she's going fine & everything looks OK. Anyone got any ideas or willing to have a quick peek under the bonnet tomorrow?? Could be dirty plugs or maybe a loose pipe somewhere (I hope that it's somethign that simple & not anything major!)?

See you all tomorrow.

My one has chirped on cold and damp morning since I did the aux belt, stops within about 1 second so I expect it will go away, similar sound to what I had immediately after Rog did my belts in the summer and that quietened down gritty fast.

Misfire: could be time for new plugs but cold plugs will fowl easier in the cold weather.

If anyone has a standard chip they dont want or I could just borrow could they bring it along please.Iceberg thinks mine might be fccuked.Ive disconnected the battery overnight and seems better but I'll know when it goes on the rollers.Cheers Bill

Great Day out, unfortunately we got our asses whooped by the datsuns but never mind.

Thanks to Craig and Ste for organising.

My results;



Car runs and feels lovely, i was hoping to get over 300bhp though!

Well - I reckon this will start yet another dyno discussion

Despite having posted very close to 400bhp at Powerstation at the end of January, I'm now down to 326bhp (276 @ wheels).

I'm really not at all sure about Dyno demon's methods - both mine and Lucifer's cars suffered clutch slip on the rollers 9they ran it in 3rd gear). My Helix organic is perhaps 20,000 miles old and never slips on the road (I used 1.8 bar on the way up there). Lucifer's Helix Organic was fitted by Motormech three weeks ago. Go figure.

I asked them to run mine in 4th, but it then span the wheels slightly, which will have contributed to the lack of power.

However, other cars made the expected power - MABR was spot on and a couple of other near-standard Coupes gave 220 - 230 bhp

So - are they loading the rollers more or is it simply a case of different rollers, different day, different results?

EDIT - Having said all that, I've just checked my Powerstation graph, and I ran 287 @ wheels, so maybe there isn't that much difference after all.

For FWD, I always allow 15%-20% losses, so your 326bhp Nigel, looks spot on.
I always thought RR's tend to give higher figures, then true road power.Again, its down to the accuracy of the RR, and the percentage losses through transmission, tyres etc, that the operator decides is warranted.
But I am seeing time and again on this site, that our humble Coupe has good and bad days. Figures seem to go up and down like a yoyo, even on the same rollers!! Very strange!

Andy.

276@wheels 326@fly is still not right IMHO

my plots



it also bugs me about the rev scale - I was told that they ran my car to 7,000rpm, but the plots stop at around 6000rpm - I know its just a calibration anomaly, but it means that I can't use my graph to work out accurately where the turbo is spooling, where the fuelling is richening up etc

Thanks guys, it was nice to meet you all, hope you enjoyed your ass whoopin by the old Datsun gang

Our results thread including a table with all results can be found at:

http://sxoc.co.uk/vbb/showthread.php?t=394711

Re the results, I really cant comment for your cars, but for 200's, Dynodemon have always been pretty much spot on when compared to other Dynodynamics RR's for the 3 shootouts we've had there... obviously all compared in Shootout mode

alright, just got back home half an hour ago.. awful drive home. nice to put names to faces though.

i have looked at a graph from december (different dymo) with no changes and i have lost 9.3 bhp and about 50 lb-ft! cant be right..

nice to see you all big thanks to MABR for organising this again.

The scale on my graphs for rpm was different this time compared to past 2 visits dont know why,makes it a bit difficult to compare the curves.

Hope you get your fueling sorted bill,just keep off the loud pedal for time being !!

Well I got to put some faces to names and learnt some thing so despite being awarded this
I think that was a good day.

bless ya cotton socks

do you want me to post your rr video?

You must have done better than me Jeff I did pass you as I crawled home.

Why was that? were we going the opposite way because I don't remember seeing any one



Yeah go for it!

http://www.youtube.com/watch?v=W9W3cuMQP2Y

what happened to you jeff ?! from the vid your boost looks low ?

Its running the standard ebv along with a PVR to prevent boost spikes.
I'm thinking about getting it set up by flea but want to get the suspension refreshed first (although its not really bad atm to be honest best one I drove handling wise when I was searching) and get the injectors cleaned just to be sure one isn't lean or anything like that.
Its running about 1.1 ish bar.

276 is my member number

Any graphs Johna,

Ben

no, am not happy with my results.. have a look on my utube for mine and jeffs video.

http://www.youtube.com/watch?v=W9W3cuMQP2Y

you need to alter your sig again now johna !!

lol, i know.. i have lost 9.1 bhp.. them results are at the wheel.

Could be worse you could be wondering where 20 went in 14 days

aye, something isnt right..

Was very cold at Johns mind and was a 10 am run.
Might be worth getting custard to look at your boost controller to sort that spike, he used to have one and set up Paul's

probs goto johns in a month or so to get the fmic on and then wap it upto 1.3 bar. think my problem is that the greddy isnt setup right, thought dyno demon would of done it for me.. also i need to get rid of the rich fuel and the idle problem.

Nice to see everyone again and meet a couple of new people

Do as Nigel said get some carb cleaner and spry it at the pipe see if you have a vacuum leak.
A bit more boost in the mid range may sort out the rich running, but that may go away once the boost spike is reduced.

which pipe is that?

If you look between the intake plem and the block you wills see 5 short pipes these are what nigel talked about.
Also check the pipe to your boost gauge is secure, the pipe to the dump vale and pretty much pipe between the maf and the plem.

i will have a look tomorrow, maybe putting the forge dumpvalve on might help.

just thought it may be the standard IC has plastic end tanks, could explain you missing BHP and the hunting if one has split.

yeah, nice speaking to you all.

I popped in for an hour or so, stayed till just after the big power/very loud sx was run and had to go.
There was 1 very nice sprinty there with recaro seats and a zender kit i think, just wondered whos was it. It has to be the nicest coupe ive seen.
Also is it a cada spoiler on the back, I only just caught a glimpse of it as it was leaving.

An interesting day, First time I've even set foot in a RR garage. Once my car is all sorted properly I would be down for taking part in one of these runs. Wouldn`t it of been better if the bhp values written on the board included bhp at the wheels as that would be a comparable figure for both sx and coupes and a proper comparison could be made between the two.

Why is the bonnet closed?
All the RR sessions I been to they open the bonnet.

dunno mate.. i normally goto a different rr and he keeps the bonnet open.
am not accepting 262.1bhp (at the fly) for a hybrid turbo when i got 271.4bhp in december at a different rr..

Thanks again to MABR for organising this meet. And thanks to Nigel for diagnosing my chattering problem on start up - that's another reason for going to these meets, to get expert advice on running problems - as well as the social banter.

I would have been gutted to not run the car after driving all that way - so was quite pleased with my 233.9 bhp as I can now sell it with proof of this. I also got some invaluable advice about the current status of the engine i.e. it's still boosting a tad high & is running a bit lean - so I know what needs to be done to sort that out in future.

Pop me down for the next run Craig - not sure what I'll be driving at that time, but I may still have the Coupe!

Anyone that likes the monamobile - PM me if you are interested.

Thanks to everyone for supporting this - we did get our backsides kicked by the SX's but that was just a bit of friendly Club banter as well as putting an interesting twist on the day.

I've listened and read what people have to say about differences in RR's and tbh this always happens after a day like this. To that end, I've agreed to run another North West RR Day at an alternative venue in about 6 weeks time. Hopefully this will be on a set of Dastek rollers for comparison purposes.

The quarterly North West RR Days will (hopefully) continue at Dyno Demon (May will be the next one) as I feel the venue and service are second to none. Steve at DD knows that I'm looking at a comparison day and is fine with that.

As for myself, apologies for not spending as much time with people as I'd've liked - still nowhere near 100% healthwise (a few people asked if I knew my lips were blue ) but hopefully getting there. It was a cracking result for me at 259 with the spec below and perfect fuelling. Last time I was there I ran 253 with a fmic, Gtech2 and a Greddy EBC. I've still got to get a K&N panel filter fitted and have the throttle cable replaced (51 degrees with no adjustment left) so hopefully a bit more still to come.

Thanks to SteA at SXOC for sorting things at his side and thanks yet again to Steve, Luke and the gang at Dyno Demon for a smooth day with excellent service. I'll post up a seperate thread about the alternative RR venue as soon as I have confirmation.

what about coming upto our neck of the woods? only cost about 50 quid in petrol.

..

that will be me

has anyone got the list of what order the coops came in at on the rr? think i came 4th at 261bhp, when it should of been 271bhp!!!!

Ill come to the next one of it localish again

Just to carry on from what Nigel was saying, I'm not really sure what went wrong with mine. Apparently the clutch was slipping from just under 4,000 revs, at which point it was producing around 305lbs/ft torque (262bhp), but I'm scratching my head as to how this is possible - given that I had a brand new Helix Organic clutch fitted by Motormech 3 weeks ago (and yes, it was the full kit )

On my way home I did a few tests, uphill in 6th etc etc and I really cannot feel even an ounce of slip, so I'm baffled as to what the issue was.

I'm going to book in to a different roller just for a second opinion, and if they say the same thing then I'll go back to Motormech to diagnose the problem. I'm not too worried about it though, the car is running great

shouldnt the lines on the graphs cross at 5250 otherwise they arent right?!

Only if the scale is the same for bhp and torque.

Its abit funny that a 20 minute slot ended up been a 5/10 minute slot, thought they would of sorted my greddy out aswell.

I thought that due to the way bhp was calculated it was always 5250 or the graphs were wrong, as there are numerous ways operaters can boost or reduce readouts?!

Im not too up on this, also isnt the reason they run in forth as its the closest to direct drive?

The RR day is for a power run, not a 20 minute slot, you (FCCUK) put it down as time slots as it normally takes that long/you wanted them, cross out as appropriate. I never put down time slots as they are always on the ball at DD unlike many other RR's we've been to..... They also take quite a bit of time to explain and help where they can, but they arent there to fix problems on a day like that, even if they do frequently.

And power figures are going to be down compared to many, its a dynodynamics RR in shootout mode and gives realistic figures

ignore my comment about dyno operaters as I now know what shootout mode is

Fair enough, i didnt know that at the time.. Half the reason i went down was to get the greddy fixed. Think am just bugged that you beat us!

Have you got any pics, you can post on here?

Cheers

Here are the ones I have, I should have taken more.....

Thanks

Heres the coops top nine,(was bored)..

N18 - 326.5 (BHP at the flywheel)
T27 - 286.1
V77 - 262.4
P67 - 262.1
X69 - 259.3
A10 - 233.9
R87 - 230.3
R85 - 223.7
V68 - TOO LEAN

OVERALL TOP THREE

200SX - 371.9
SKYLINE - 362.8
20VT - 326.5

According to Steve at DD, most of the performance Jap machinery have fuly mappable ECU's. This is why they can make so much power, and thats reliable power too.
So the 200SX boys, have a distinct advantage over us.

Andy.

In order to do a "compare and contrast" exercise, I've arranged another North West RR Day at this place;

http://www.ricwood.com/

For those of you interested, get your names down on the seperate thread;

http://www.fiatcoupeclub.org/forum/ubbthreads.php?ubb=showflat&Number=779780#Post779780

I take it back, they have changed their RR............

The top 3 were 200sx, Skyline, 200sx then it was the 20VT......

opps, i missed the 331 bhp out by mistake

Just looking at Nigel's results.

He got 287 bhp at powerstation and 276 bhp at Dyno Demon, as he said.

Surely it cannot be a coincidence that these figures are so close?

If they are both correctly measured then clearly the method of working out transmission losses between the 2 different kinds of rollers is massively different.

I suppose though that it could quite easily be coincidence, but still, odd

Matt - I thought that as well - its entirely possible that I have circa 280bhp @ wheels, but which one is the correct flywheel figure?

I don't suppose it makes a lot of difference, as the wheel power is what drives the car, but I'd like to know

I'll be putting it on a Dastek dyno in April, so it will be interesting to see what that comes up with (won't have done any more mods, so I'll run the same boost as well, just for consistency of results)

Hi Nigel,

One thing I need to say, I don't buy those figures of yours .
There are quite a many things which are against them:
your setup, your boost rate and your 1/4 Mile results.
They are all speaking more or less 400 bhp or more.

About the boost, in your graph it shows that you used boost of some 1.6 bar in RR run and you have "only" given some 330 lb-ft (447 Nm). With that amount of boost I have had with GT28RS and my friend even with GT28R torque of +345 lb-ft (+470 Nm).
Wheel spin I understand very well, because the RR where were use to visit need to run our cars with fifth gear just because there is no wheel grip with lower gears. The dyno is Bosch FLA 206 and it is based on inertia.
So the dyno run with third gear or fourth might have caused the situation, which is normal for example in slippery road, straight after the grip is lost the boost goes down. Maybe this was the reason for so early stop in RR.

There is possible for the boost leak, which I did have in my last +400 bhp RR session. Look the curves in "My Coupe Project" by hani, I have posted my graph there with couple of pictures of the broken hose.

The 1/4 mile terminal speed, your terminal speed of +115 mph is way higher than what can be reached with 326 bhp! I never could go faster than 109 - 111 mph with three times measured app. 350 bhp setup. Same data speaks the given results in "Hall of Fame" form the cars app. 320 - 340 bhp.

So, don't give up . There will be a proper RR some where, which is calibrated right and gives you the "real" curves. And I bet that next 1/4 mile run gives you the truth by terminal speed, what is the power level you should stand.

- Jari -

I have noticed, that Dynos that cause a lot of slip etc, are ones that use two rollers. Single rollers eliminate this, as the tyre sits ontop, as opposed to sitting on the side of the roller. See this;-
http://www.tracknroad.com/
This RR, is considered by many to be the most accurate RR in the country. Its why so many race cars are set up on it!
Only real way to eliminate any errors, is to use a Hub Dyno .

Andy.
