As above really? A car I know claims this power and just wondered if it could be true? Its a 1999 Uk spec with STI spec IHI turbo, Motec ECU full decat, induction kit, bleed valve. Aslo apparently has STI engine though it looks like a normal Uk engine to me (not a red top). Can that power be acheived with the standard top mount from a UK 1999 in place??

 

he probably is talking ****e! to reach that power he'd need an uprated intercooler and larger injectors and fuel pump..and doesnt know his car too well really, cos nobody in their right mind would upgrade "engine" and turbo etc with doing the i/c! wouldnt even need a fmic, sti8 tmic would do the trick..

 

just thinkin there, sure an sti v4+ can take only safely 320bhp roughly on standard intercooler, id imagine the max for a uk turbo would be 290bhp tops

 

my uk99 turbo made 330 at powerstation.

 

Interesting stuff. I thought the same as flat4_ire. Why would you do all that work and not upgrade to at least an STI intercooler or better. Suppose only a dyno would put an end to my speculation!

 

Yours was on a STiV i/c IIRC?

 

why would you have a motec and a bleed valve

 

Agreed Bob,
the core may be a little more efficiant but the dimensions are the same and the heatsoak issues will be the same, more as a point of reference than an absolute.

Andy

 

Exactly what I thought mate! Surely that defeats the purpose and was one of the things that made me doubt the power claim in the first place.

 

many people run aftermarket ecu's with external boost controllers.
Iirc Andy.F is using a dawes device on his car with an Apex'I PowerFC.

(or at least he was recently?)

 

Oi, don't give away all my secrets

 

and ur running 330bhp on a standard my99 uk turbo intercooler??

 

Easily available single scroll STI turbos include VF28,29 (RHF5) and VF30,34,35 (RHF55).

RHF5 will struggle to flow enough air for 350bhp unless you run race fuel. RHF55 will (supposedly) manage 350bhp with a bit of octane booster.

MY99 UK TMIC with samco hoses is as good as an STI TMIC. But you will struggle to make 350bhp with either (normal disclaimers apply )

Currently running 399 bhp/ 382 ft/lbs according to Well Lane anyway on my MY99 UK Turbo 2000
Although will be changing to an FMIC soon.

Spec as Follows:

VF34 Turbo
STI 5 Engine with sti 9 Crank
Eagle Rods with ARP Bolts
CP Pistons.
Heads polished flowed and pocket ported
GT Spec Headers
Full Decat
APS Cold Air Feed
Samco Inlet Hose
Fuel Pump
Apexi Power FC ECU and Andy F Map.
6 Speed gearbox
Exedy Clutch
RCMS Lightweight Flywheel
Engine Pulley set

So even if Well Lane's Rollers read on the high side I doubt they will be nearly 50bhp out.
I'd say 350bhp on standard UK intercooler is a fairly safe bet.

Don't forget the turbo too - intercooler has to work harder if turbo is pumping hot air. 350+ is easy on stock tmic with an 05/06 and right supporting mods......easier than on some aftermarket tmic's if you're talking about more than one power run

dazdavies, 399 bhp/ 382 ft/lbs is unbelieveable on a VF34 and MY99/00 TMIC

Well dun.

F

 

on a 2.0litre aswell!

Floyd, get yours upto Well Lane

 

Which injectors?

 

F

 

550's

Although I am currently looking at a garrett/ihi hybrid and 740's.


I think the 399bhp is a little on the high side but its certainly around the 350 - 360 mark

 

Hey guys, it's all in the mapping

 

Fack Off! Maybe in the fuel though

 

I have never run anything but optimax.

Bang goes that theory!!

 

399/382 on plain optimax....on a 2 litre with a VF34/5 and std tmic

Must be bloody quick

 

When I fix my buggered 6 speed (4th gear) I'll do some quarter times and let you know. On the road though it certainly seems it.

 

Having a 'built' engine with flowed heads, better shaped piston crown, different squish and a nice big bore cold air feed can improve the efficiency considerably.

Andy

 

Built the engine myself. Although I did have the headwork done elsewhere. Its done 12k miles now and overall I'm pleased as I am no mechanic.

I bought a CD manual from E bay a shed load of tools and did it all in my garage and my driveway on my own. Yes, even the six speed box. It was heavy as hell. It involved a trolley jack, engine hoist, axle stands, weight lifting bar for leverage and erm quite alot of swearing and kicking spanners and the like around. But pleased with the rsults and it really does feel quick considering the turbo I am running. But like andy says. It's all in the mapping and he really did do a blinding job.

 

Didn't read the spec before posting, sorry. Still think that's a pretty major increase in VE to get those figures out of a VF34 - well done!

Richard

PS: Andy can still fack off though

 

As daz readily accepts, Well Lane can on occassion read high. I would however be surprised if it's more than 10% high which would put power around 360bhp.

Andy.

love you too Richard xx

 

OMG, some of you guys are getting very tolerant in your old age

Daz, apart from changing from a VF28, to a marginally larger VF34, what did you do, to go from the 330bhp/300ftlbs you got at ScoobyClinic, to the 399bhp/382ftlbs at Well Lane.

Mark.
