I raced a std coop in my coop when I had it which was 328 bhp and I left it for dead by 110 was 11-12 car lengths in front.

when its a only a small difference in power and your already moving, who is in front depends more on who puts there foot down first, I can remember when I raced Nigel on the way to the pod a couple of years ago he had a 28R and me a RS when we were rolling there wasn’t much init but once on the strip there was half a second difference over 400m both of us were capable drivers so there was no difference in launches,

Anyway jbt your gonna get rinsed HA HA, I think Jamie must have run out of road, or his car must have been broke, or maybe you were just lucky but in a proper race were the road is long enough you don’t stand a chance.

So you want me to humiliate Jamie on video.
Nice,
Some chap in Germany who is on here worked out the difference to the nearest 0.5 kg and he said that mine is 20kgs lighter.I disagree i think it will be lighter than that,prob more 100kgs lighter.
I also have lightweight wheels,which make a huge difference imo.The loss of trac with these was massive compared to the coupe rims i had on it at first which you can see on my car on the link below.
On top of that the bravo bonnet weighs nothing whereas the coupe takes 2 of you to pick it up.

So who fancies recording me kick Jamies ass again.
Im looking forward to this one....
Jamie hows about we settle it at Jimbos runway bash.
And no sneaking nitrous in....

P.s i cant help feeling too old for this tbh,but what the hell...

Johnny if your car is 100kg lighter than a coupe then with your power you should have similar bhp per ton I would have thought but I'm with Dan, although you will get the jump, Jamie will undoubtledly pass you. How can a superspool have a better top end than a GT28RS? Which turbo would you rather have???

A superspool! hence why I sold a 28RS for one.



(I'm probably in a minority tho )

Eh, you didn't?

Jonny, like you I'm up for a blast, when is this meet you mention??? I've driven a number of high power coupes and I know that a rolling start will show its power vs something peaky by comparison.At the end of this little tussle it will prove than one scenario will favour your car and one scenario will favour mine.In terms of pure straight line grunt I'm confident I'll have the edge as one thing you can't deny is the aerodynamics will play a factor as the speed increases which will be in my favour.

Jamie

Okay so to recap for you deaf people,
The live map has more power than the chips as there specific to that vehicle,so i have a advantage as i will have a perfect setup all through the range.
Also the superspool comes in nearly straight away with next to no lag.Once it does this its at full boost pressure until the redline.
Agreed a gt28 is the better turbo for power but upto 300 bhp i would think a well tuned superspool would beat any gt28 of the same power easily.
The gt28,s i have been in are inpresssive but are very like driving a Honda vtech..All the power is after 4K
So already i have got 2000 revs advantage and you wont recover from that on a straight run.
The people who critisise the superspool have never driven a 20vt with one on.
Jamie i will Pm you about having a tinker with the smokers as discussed earlier.
And sorry i was about to say Brewster on the phone,lol...I recognised the voice but couldnt think for the life of me who it was.

No worries

Jamie

Yes, I did. The 28RS isn't for me, I don't want massive top end, or to faff about with a 3" downpipe. I really wanted a top spec hybrid like a superspool/GTI-R, so I sold the 28RS, and now I'm just waiting on a superspool...

I agree, the superspool is better suited to country roads and track. It gets you out of corners much quicker

jonny i disagree, with a driver who knows how to use his powerband you would have no advantage which is why TD's are slow I don’t see the point in having loads of torque before 4000 rpm you should be launching around 4500 rpm and holding it there until you gain full traction and once out of first your revs shouldnt drop below 5200 rpm( unless your gay) I suppose it might be an advantage when on the motorway in 5th and you can't be arsed to change gear but thats about it.

Yes but if you hold the revs there and launch youll have a serious loss of traction.
On a 4wd i would have no chance if the power band was there straight away.
But the forum always has a difference of opinion.
Jamie knows without a doubt that he will loose and the footage will convniently go missing from the posts,
some sort of forum issue.

This leads me on to a question, probably a daft one, but here goes...

Say a bottom end were to be rebuilt and say bored out 2.3 0r 2.4 - Would there be any point putting a superspool on and what would the estimated power figure be?

JBT - Let's take your car as the example - same specs, but a different capacity.

I will settle this then,
My car is slow and i have a little pecker.
Now back onto topic.....

Would it be worth doing though?

Personally if i did a 2.4 i wouldnt use the gt28 or the superspool

I agree with Dan in that once rolling you should never dip below 4000rpm so any low down torque advantage is made redundant. If you want to have a nice, easy, relaxed drive allowing overtaking in 4th from 2000rpm then a superspool is right on the money.

As for going up against Jamie, well it sounds like it could be close but at the bigger speeds I can imagine the coupe pulling a few lengths.

Jamie, what was your peak torque and wheels figure on your 340bhp run?

gt28 / superspools are way too small for a 2.4, you'd run out of flow capacity by about 3.5k ( remember,t he 2.4 is shifting almost 25% more of everything )

mine just squeezes under the OEM heatshield, but even this monsta spools up by 2.3K, said to be good for about 500hp, but we'll soon see

as for spec, no idea, just a big roller bearing jobbie

309ftlb

Jamie

Graph?

Ross

I'm guessing this is caused by a boost spike and not held for any amount of time?

oooooooooooooooooh...a chance to show off da graph
and a little piccy as well

JBT, for your mods you do seem to make a sh*t load of torque and hold on to it relatively high up the rev range when compared to some of the older results superspool results ... i'm wondering how much difference the blueflame makes, as IIRC most others with this turbo don't run this exhaust?

The Jintel,JimO, Jayzee 20vt runs a superspool with a BF exhaust

As seen here virtually pulls the same power as JBT, at the time of the run, the car had a slight leak in a hose and the greddy was set up better after. Which I think is the cause of the slight dip at the front of the torque cuve

So prob the JBT car has the same figures as the JJJ car

Very nice! It certainly seems that 2.75" is the magic size exhaust for this turbo ...

Interestingly enough i actually got the car mapped on a 5 quid bleed valve as we couldnt get the apexi avcr to hold boost properly..
So with the greddy once i set it up,i should see better results as it holds the wastegate better..
Either way though i was very impressed with the results on the day.
Everything on the car is mega low miles,and the turbo and exhaust were new.
This may also be responsable for good figures.
This is also the reason i invested in tc as it was undrivable.Unless you wanted to be dead within the hour.

Johnny, that's a really smart conversion you've done well and a nice torque curve, comes on early and holds a good figure solidly throughout the rev range!

100kg lighter, I thought it would probably be along those lines, would make a for a very quick car.

So,... have you arranged a date for your head to head then?

Joe

Yes doctor,
Jimbos runway bash will do nicely..
I will be settling a few grudge matches there..
providing im still in the Uk then...

Hi Johnny,

I did the calculation but you are getting parts of it wrong.. the 20 kg difference is between the 20v n/a and the turbo engine.. so you are right in thinking that the Bravo is 80-100 kg lighter (1365/1385 Coupe to 1265 /1285 HGT+Turbo)
and we all know that 80-100 kgs has massive implications on performance.. good for us bravo20vt's

Sorry plasticononmonomininium,all your effort and my little brain makes a mess of it..
I couldnt remember for ther life of me your name,and i still cant...
But im glad you worked it out as i couldnt.

Have you got any piccys of your bravo
