uk turbo, with full decat, ported headers and up pipe, vf35 turbo, ecutek remap, im guessing with these all fitted it should be running around the 330bhp mark, so just how fast will it be? and will the gearbox cope ok with this power? and the clutch? will it feel a lot faster than it is just now, only got full decat on it atm. came off a round a bout yesterday behind a bmw x5 who was nailing it and i kept up but i was suprised just how quick it was, i need lots more power!

 

Was the X5 a 4.6? If so they can be chipped to 350bhp+ no problem.. no slouch once moving

 

Pretty quick, although while the gearbox may be fine the clutch will moan after a few months or more...post your location, someone will take you out I am sure...

 

im in edinburgh up in scotland. yeah the x5 must of been one of the big engined petrols, tbh i wasnt trying to race him or anything just that he was driving like a ****, but off the r/a up to nearly 80 wasnt anything in it, although i didnt put the foot down unitl i was in 3rd and was suprised i wasnt gaining on him. :-( my previous classic was remapped to 270bhp and then my version 3 sti was 280 out the box and was a fair bit faster than my current uk turbo hence why iv started to mod it. i really wanted version 3 or 4 sti type ra in sonic blue but couldnt find a good one anywhere. will just have to carry on modding.

 

I've had quite a few STI's mapped to around 325/330 bhp and done properly nothing much will get away from you....... of the mark that is! I never had any issue's with gearboxes or standard clutches at that power either. There is no compensation for big cubes at end of day

 

My classic was running around 300 bhp, no probs with either the clutch or the gearbox.

And yes, it was quite quick.

I can hardly wait to get the new version run in..........

 

The X5 4.6is E53 (if thats what it was) is quite a power-house out the box, but with those mods you mentioned your classic would comfortably destroy one without too much effort.

The Beamer comes with with about 340bhp and 354lb ft torque, although they weigh over 2 tons so a lot of that muscle goes to waste on moving all that flab.

0-60 in 6.5 seconds and 149mph, midrange they're pretty strong but I'd expect any classic running 240+ to comfortably beat one due to superior power/weight. The X5 at most only has about 156bhp/ton.

 

the vf35 seems to be the turbo of choice as an upgrade from what i have read on here as well, was looking at a hybrid td04 but they seem to be limited to 300bhp where the vf35 can run more power and still has a quick spool up.

 

Cmon, my house weighs less than an X5

TX.

 

I know of an X5 running 550bhp (0-60 in 5.6 seconds GPS).

My point was he could have been up against a real beast so don't feel too gutted if he felt sluggish...

 

andy forrest mapped my v5 sti to 334bhp an its in a different league to my 290bhp uk classic an it chewed up an spat out honda s2000's etc. V5 has only accounted for a GTR lookalike R33 with a big FMIC so far........
No problems with either gearbox or clutch etc, probably break one tomorow now ive said that!!

 

As above. The difference between 280bhp and 330bhp is massive. You can pull out and go past 280bhp motors in a 330bhp car.

 

UK turbo gearing isnt exactly brill, its quite long and you can find that the power band is quite wide, so you can lose out there, your v3 is quicker due to the shorter gearing, so where as a UK turbo with 330bhp is quick, a v3 STI with the same power will be quicker due to the gearing.

My experience of selling my VF35 to a UK classic owner was....
At 330 bhp,

1. The clutch gave up soon after fitting.
2. It was a bit laggy after a TD04.
3. It was as quick as a 380 bhp New-Age STI

HTH

dunx

 

mine was running the 330 mark and killed the clutch twice, and now its killed the box

darc

 

BAD DRIVER Thats what happens when you launch your car every chance you get.

 

mines been running 346bhp for 2 years now, no problems with clutch or gearbox!! (yet)lol
it a v5 sti

 

mmmm. so the vf35 is laggy compared to the td04, think ill go for the andy forrest hybrid td04 instead, i like my quick spool up, and 300bhp should be enough to keep me happy.

 

Can this be transposed to a 330bhp newage?

 

Get a VF22 and blow everything away - just dont get caught in the wrong gear!

 

Im running 330/320 and it's plenty quick. Put it this way it spins the wheels in second in the wet. If you can drive it will keep up with 90% of cars on the road

 

im running 300bhp with a vf34, 3inch with decat, bigger uppipe, 3 port and ecotek remap at 1.25 bar no problems with the cluch or gear box

 

My classic is (proven) quicker than a 460hp hawkeye from 30-130 with me running much less power

TX.

 

Budgie wont like that tx, shamed him now

 

I have a WRX (fairly standard engine wise) and a 2003 4.6 IS X5 (347bhp). The V8 really doesnt drive like it weighs the same as a pair of council semi's.
The sports suspension, gearbox, brakes and engine give the feeling of driving a car that is heavier than a mondeo but certainly not as heavy as an SAV. A 330bhp wrx or whatever should tiptoe past in reality though just through being lighter if nothing else.
off the mark the x5 is pretty impressive, same as the subaru, no wheelspin and in manual mode (5 speed) the gearbox just seems to rev out in every gear very quickly, never gone fast enough to test that in 5th though!.
On the move it is best though, pulling from 30-80 or whatever feels reasonably quick but then you are wrapped up in a huge comfy nappa leather sporty seat and the feeling of speed is toned down compared to the wrx. With a 100 litre fuel tank, I wouldnt be trying to out run it either as the fuel consumption isnt much worse than the impreza either, never mind a 330bhp classic.

 

so a 400bhp classic is quicker than a 460bhp newage Tx...

Is that "just" or are we talking car lengths

A good comparison that's all... +60bhp to make up for all the extra lbs

 

Haha whats the point in driving a car like that like a pansy?

i knew the box was on the limit so why not run with it till it goes bang and then replace with a 6 speed

it did do a few 1/4 mile runs just all the other time it got taken care of.

darc

 

Almost 3s quicker to 130 & I'm not saying whos car it was!

TX.

 

lol... no names bu...g...

 

mr hat was that you i saw the other day up gorebridge way????? saw you at niddrie then gorebridge area
