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..

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

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
