Thanks to Barbz @ Torque Italia !!

Some of you will know that over the last few months Barbz @ Torque Italia has been doing some very special new tuning modifications on my car. After months of hard graft from Barbz I have got the results of the work back -

On normal fuel the car made 577BHP using water inj. I don't trust water injection (and don't have a DDS3 or similar) so without the extra advance it gives the car made 547BHP with 4xx lbs/ft (not got the power graphs back) all at a relatively modest 1.5 bar boost and relatively conservative advance. That's over 480BHP at the wheels.

On 102RON fuel without water injection it is making 616BHP and 480lbs/ft torque still at 1.5 bar boost!!! with plenty more to come by using more boost or a higher octane fuel. That's 470BHP/tonne with a full interior.
Also with this much power and where the power is delivered there is absolutely no doubt that it is capable of over 200mph.

What is most impressive is the fact that this has been done on a GT30 hybrid (like a GT3076R) so on my 2.4 it is pretty much lag free!


Have had my traction control extensively tuned for it as well so it can put most of it down in lower gears and all of it down in higher gears

I can't thank Barbz enough for the untiring effort he has put into my car, he carried on through a mass of setbacks and complications. The result is a tribute to his legendary engine tuning abilities! Truly a tuning magician!!

Cheers to everyone on the forum who has been supporting me in this!

Will post up graphs when I get them

John

Wow - fantastic - congratulations

Wow - well done both of you!!

So come on, how much do I have to save up?

Great! Back to the top of the tree for JohnS now get to TOTB and decimate that top speed time

Fantastic work John and Barbz, well done to the both of you

WOW is all i can say.. fair play to Barbz and Yourself

some video's of tacho or else ?

pleaaaaaaaaaaaaaseeeeeeeeeeeeeeeeeeeee

wow, does that now make it the fastest coupe in the world?

Nah, theres still that dude in South Africa with his claimed 200MPH+ coupe if he ever finishes it .

Oh what ever happened to him?

Looks like JohnS is the daddy of the block now

Great results JohnS! Have you tested the engine with BioEthanol E85?

Amazing results John. Shows the true potential of the 2.4 now. 10 sec quarter is now in sight.

Ross

Well done John and Barbz.

Matt from SA got 180 or similar, but never hit 200, so anyone getting more than that has the high speed award.

Great work tho John and Barbz, some serious power, esp if you're getting it down in the early gears!

Thats fantastic! Well done!

what traction control are you using?

Fantastic figures - Barbz really is a Magician!

OMG John, that is truly amazing

Congratulations!

Can you give up a spec list....?

Barbz, the magician, all hail..



THE KING IS BACK!!!!!

Joe

ps john,..how is the gearbox holding up?

Bring it on John!

I was expecting figures like those - and it's all finished for TOTB - hope you'll be there, as the top speed run will truly be yours.

Hats off once again for being the first to try something new.

I knew the 2.4's had much more potential than the 450 bhp odd that they were producing - and you're still 'only' using a GT30, which really sets the engine apart from 2lr engines (not just coupe) that run big power but have to go much bigger than a T30 to get the headline figure and suffer below 4K as a result.

I'd love to know more detail of the spec like who did the manifold, mapping etc. but dont know what you can or cant post up.

John I think we need a pic of the engine and car just to make sure you really have got what you say in there, and haven't just slipped in a used RB211 or something...

How/when are you gonna test that 10 sec quarter mile and/or 200mph? Is the Pod long enough for that? Are AutoItalia doing another day this year at the Pod, I don't think so

Wow!.... Glad that its all finished and your the first to manage over 600bhp. Will be good to see it at TOTB, engine pics please too (manifold, wastegate, GT30 etc)

P.S You have twice as much power as me
P.P.S Well done Barbz

**Cough** Brize Norton John?

I'm on holiday in Italy, but this deserves a mobile entry! Fantastic results, just what was hoped for. I know how much Barbz has toiled with this build so the results are vindication and reward for such effort. Now give that car a f****n good clean John

Amazing amazing amazing!

perhaps it deserves 2 entries then Leight....

Amazing !!! always hought the 2.4 had far more to go,especially now the 2ltrs are getting well over 400 bhp............well done to John for supplying the funds to show what Barbz can achieve,a credit to you both

Wow! How much boost are you looking at running for the top power run?

Congrats to you and barbz

Very very well done, Johns
Honour to whom honour is due!!!
You (and Barbz) as well are persons, who let participate other people in their success - you help and support other people with your really big knowledge... a really big benefit for this forum!
Thus this amazing power crown has got the right owners...
Barbz and Johns!!!
Congratulation from Germany!
Juergen

Well done to John and the magician Barbz ! Hope to see you at TOTB .

Phil

The King is dead, long live the new King (again)

That's more like the kind of figures the 2.4 should be producing. Looking forward to seeing the graphs while I decide my next move. Are you still running the C&Bs?

Congratulations

JohnS will not driving at TOTB

But well done to JohnS and Barbz for all the aggreviation both of them have gone through

Congratulations John, that's amazing power.

Barbz = legend.

As above - now where's the RR charts?

congratulations mate..as usual barbz magic is amazing.

thanks for all the positive comments!

I'm on my hols now so will post the graphs up when I get back.

The traction control is the new Motec v3 version (available on M600 and M800) which is amazingly configurable. I can floor it in the pouring rain and there is no ridiculous spinning up of the wheels - the car just goes.

I want it! lol

I saw your old Skyline intercooler for sale, what have you replaced it with? must be HUGE!

John - get you B*TT to TOTB - now!

ok, will be there

good work John, i'll be keen to see my results on the 11th, but am going to be very cautious, as melted pistons are something I cannot afford

i'd be happy if I get a measly 450 ( and a very reliable 450 at that ! )

the torque is what i'm after tho'

Yay!.....

P.S Have you update the hall of fame yet John? (that would be the first thing I did )

Chris

Thought you might be - you tease.....

I think we all know whos gonna be driving tho....

Ross

Me?

Well it could be worse.......

Ross

Well done,its been quite a task by the sounds of it.
I will be going to totb myself so it will be nice to see the coupe causing the Japs problems again.

Yup - it was the first thing I did early this year

hi john !


very impressive results

do you still use the same gt30 hybrid with 0.86 t25 turbine ?

if so, how did you manage to get such a high output with this turbo although it should be produce a max of about 500hp ????


macki

Spec! Spec! Spec! Spec!

don`t think so guarded with his life

Have updated what I know. Have lost my bl**dy graphs somewhere so cannot post them up at the mo. I think I may go to an independent dyno anyway to prove that it isn't dyno-specific.

Anyway, rough spec of the engine
- Torque italia 2.4 engine inc. forged pistons, rods, crank etc. etc.
- Stage 4 head - oversized in and ex valves with nimonic ex valves
- Custom twin-scroll ex manifold with twin chambers and twin wastegate exits. Basically a heavily reworked Saito style one that was then rewelded up to the final spec as there were a lot of issues with their original design
- Tial 44mm external wastegate with 0.7 bar springs
- Custom 3" exhaust with special lightweight/low loss silencers (power achieved with 3 silencers but I can remove 1 of them and unpack another one). Fully v-banded for better sealing
- Custom GT30 hybrid
- Torque Italia fully braided oil cooler hoses
- Remote oil filter modification with braided hoses
- External fuel pump (Bosch 044) and swirl pot with braided hoses
- Special custom push fan conversion (improves the inlet temp by blowing the heat from the radiator away from the FMIC.
- Full 6" to 4" straight inlet
- Helix twin-plate clutch

The ECU stuff
- Motec M600
- Motec v3.3 traction control
- Wideband lambda correction
- EGT correction

Spoolup is around 3200rpm for 1 bar boost a bit more for full boost, but it is some way higher than that in lower gears as it is a big turbo still. On a dyno run it spools up about 1500rpm later than on the road now which is quite bizarre.

Currently got an 8000rpm limit and max power is pretty near the limit - around 7700rpm if I remember correctly. The turbo would probably make over 400BHP up until 8600rpm I'd guess. Boost hasn't been fully setup and is a flat 1.5 bar so my peak torque is actually at quite high rpm - something like 6300rpm I guess, although if I up the boost lower down it will make more torque and earlier.

Was originally going to get it mapped with a larger turbo (GT3582R) but had some problems with the turbo so is on hold. Would probably make around 650BHP on that turbo with normal fuel and full boost at about 4500rpm

As I said it is all thanks to Barbz for a lot of effort and requiring a lot of fabrication work.

Perhaps Nimonic ex valves?

rich

yes, apologies

Are you coming to Brize Norton John? Presumably you can hook up your laptop to the Motec and log the data (hint hint,top speed runs..... ;).)

Chris

That is some amazing effort there John, and a lot of us wondered what was going on with you being so quiet and selling your old bits

Top speed run would be good, however I would have serious concerns regarding the Coupes safety at the speeds this engine could propel the car to!, I am sure that the magic 200mph is within reach!!

joe

Jeez, that's incredible John. To think, I can remember this car in Windsor in standard form, with just the usual mods. I probably wouldn't recognise it now. Amazing. Can't wait to see your times and speeds for that. Hope you'll be at TOTB to wipe the floor with the rest of the FWD class!! LOL!

Really wanted to do brize norton but I can't as I have a few bits to fix to make sure the car is 100%.

Cheers MrB!

Hello Johns,

have you reached this power with your "old compression ratio" of 8,8:1 or have you lowered it a little bit?

Thanks
Juergen

Mine is at least that if not more
Thanks for your email on your new map btw it was interesting comparing notes!

The days of lowering compression are gone... increase compression and increase boost

1.9 bar is a bit OTT Flea

My day was mixed with a 1.4bar run....

found some probs, major ones needing addressing with intercooling ( but I knew that anyway )....

nearly cracked the measly 400hp barrier, but next time, with a working variator, 450+ is easily attainable

this tuning lark is a real challenge

The only unusual "mod" that day was the Alfa alloys

I hope to see your 1/4mile best time as soon as possible. Do 10 sec with anterior traction is difficult but possible if strip and tires are good.
compliments for result

Thanks again for everyones support. Will be running normal fuel at TOTB VI which is actually 557BHP not 547BHP. I have the graphs now but all my stuff is upstairs in my house as the area is on flood alert
