I wish i could just wind MY boost up.... Reckon i'd see 400bhp at around 1.6-1.7 bar??
Only ever gonna be 1.3 tops though... Unless i go for stand alone ecu?? Not likely while this CREDIT CRUNCH is on!

I wanna be a HIGH BOOST HERO

Nick

Most of the time you attend a R/R you are hoping and praying your beloved does not blow up

THEN !!!

I have never seen the likes before. You could use the example Big Foot,Santa Clause...

You just don't believe the above exists( seen nearly 400 on Mattys with my own eyes)



Its endearing but strange at the same time.

Long live "Mattys coupe"
Ps Just to piss him off


Ps 2 turn it up more, it loveS it

Wow. Impressive stuff Matty!

nice job mate, seems like every one is wishing it to go bang!

i hope she stays as in one peice!

any more planned for it?

makes my 241.1 bhp pointless lol

Not wishing Marco !

Just wondering when !

HAHAHA

need some faith in the engine, as long as its loved and looked after and not abused constantly, cant see why it will go bang!!!

and if it does go bang...at least he will destroy it in style!!!

so i take it 400bhp isn't ok on standard bottom end? if it is thats quite good for the rest of us

there have been lots of discussions on this in the past and people have mixed opinions. A lot of factors come into it!

I think Matty's proved that it's ok for 400bhp.

Question is how long is it ok for.

lol. i had the same thing with the skylines. to start of with people said 400 bhp then after a year 450 bhp the year after that 475 and then some went to 500bhp and most lasted so do people actully know whats safe on standrads or is matt a test lol

I think Matty would be the first to tell you not to expect to run 2+ bar of boost and upwards of 400 bhp and not expect it to eventually go pop.

ok the other thing is what about how the car performs?
matt whats it like to drive? i had a 425 bhp skyline rwd and its got no tracton at all in 1st 2nd and some 3rd so whats it like fwd?
to be fair i am very impressed with the coops traction for fwd indeed :-)

This has been done to death.

You can FUBAR an engine running 250 bhp if you tune the car wrong. Take a wild guess how long a standard engine and turbo will last at 2 bar.

A worn engine may well pop with only a chip and no other mods.

IF you do it right then up to 350bhp is a general guideline on the standard internals - 350lbs torque on the standard rods. If you want to go for more then dont cry like a girl when it goes bang.

THE END!

ok fair play sounds good. what does 350 bhp coop feel like though as its fwd i just imagine a cloud of under steering smoke and a helpless scared driver lol.

Nope - pop over and I'll show you.

Over 400bhp isn't the worry, as such, it's the torque that breaks traction - and 'possibly' standard bottom ends...

A Coupé that's set up well* will 'scare' a few things on the track to say the least.

*I am including brakes/suspension here.

I'm not by any means saying that it's OK to run stupid amounts of boost/torque through the standard engine, and if you blow up your car doing so then so be it, but I think the general 'oh you can't go over 350bhp on the standard engine' is there to be played with.

At 320bhp I get no traction at full boost in 1st gear at all, I have to catch it on part throttle when the boost comes in or it's instant rev limiter stuff and lots of burning rubber. 2nd hangs on in the dry and goes like crazy, in the wet it wheelspins at full boost. 3rd gear is always fine, you'd need more power to spin the wheels in 3rd

I dont think the understeer is that bad, if you hold on tight.

You mean Torquesteer

try second gear 3.5K rpm B road, floor it and steer to overtake the car in front. When you're back from the ditch we can discuss it further
Serious, I'm finding my self lifting off just as I get to the opposite lane and booting it again as soon as I'm level with the other car.
Hopefully this will change next week as I'm halfway through the Racelogic installation

V.

That's 36mph in 2nd gear. Why not try to fall back a few lengths and then put your toe down in third gear from 40mph instead? With a GTiR mine flies from these speeds with minimal fuss

Cos it's not as much fun.

Not really, I dont get any torque steer in a straight line. Just if I decide to boot it whle going round a corner it doesnt want to go round, but it can be forced to.

I must say that I find the coop great for traction and much better than my skylines as they where rwd and quite powerful and to be fair you had to watch every move in it because it was ready to kill you all the time.
Main thing is how a well setup coop would stand against say a Scooby or evo as I am always put off with fwd as I doubt how capable the car is even though I find them much easier to drive on the limit.

too right... and if you hit an unseen puddle whilst passing on full boost, hang on !!!!

As the late great Colin Mcrae would have said;

"If in doubt, go flat out"

Which is exactly what I did at Knockhill, the back end of the Coupé can be very playful! Torque-steer is especially fun changing from third to fourth in the wet beside an Evo...

so a well sort coop will give the big boys like scoobys and evo gtr's a run for there money as i doubt they can?

It depends how it is driven, I witnessed Nigel beating high powered Exiges and Evos round the handling circuit at TOTB.

Stop doubting.

and that was with only about £450 worth of suspension mods - hardly a money-no-object car ( as many of the TOTB cars were)

My car is set up to be neutral wherever possible. It means a bit of understeer at low speeds, but its VERY predicatable at very high speeds - totally planted.

Once rolling, it would be a pretty quick EVO or Scooby that would trouble me round a track. Sure, I'll get beaten out of hairpins and the like, but once in second gear or higher, I don't have traction issues, regardless of how much power I run.

I'm pretty confident that if I wanted to, I could set the car up to be "pointy" and have it turn in with as much bite as your rally slags. However, with the mileage I do, I don't want it to be hard work to drive, so its set up more as a hard GT car, than a track weapon.

I know it would be quicker if the rear wheels were driven, but not by very much.

well its just i have driven quite a few skylines in my time and handling wise i think a coop could stay with a gtst or maybe a gtt but a gtr i doubt and power wise any skyline with over 450 bhp in a gtst or 500 in a gtr is going to pull away and they are common power outputs now in skylines.
i want to be proved wrong to be fair as i would like the coop to hold its own against them
