Anyone running one of these yet.??

 

You are

 

Not as good as the SC billet GT35

 

Followed there progress on NASIOC and from what I have seen the larger 35 does not compare to Clinics/Blouch offering. I run a Clinic billet and it goes quite well

 

Bump anymore info?

 

My project build just completed - 647HP with a 2.5L on standard fuel. Minimal lag.

 

TX.

 

(Build by David @ API Impreza and Mapped by Bob Rawle)

 

spec please im after a 35/82 dont know whether to go for gtx or sc at mo? also what does it spool up at? judging by some post above, they have had one or just repeating what they have heard

 

Its a P1 with a full engine rebuild on an EJ25 with Darton liners, forged / balanced internals, 6 speed box, triple plate clutch, 1000cc flow matched injectors, etc, etc.

Turbo is fitted with 0.82AR housing, and full turbo / exhaust headers / downpipe are Zircotek coated.

Running 1.5 Bar for that power level.

I dont have RPM figures as i havnt picked it up yet, it was only mapped and measured today.

 

647bhp @ just 1.5 bar on road fuel ?
Something sounds amiss there ! I've mapped a GTX35/82 myself and it didn't make anywhere near that at that boost, in fact it took nearly 2 bar to crack 600bhp on Vpower.

 

You sure you mapped a GTX and not a GT? The GTX flows up to 20% more...

Thats the figure given by David @ API, and it was mapped by Bob Rawl today

It was pulling about 500 previously on a smaller turbo, so sounds about right to me.

Doing some quick calcs - 647HP requires circa 65lb / min of air - seems well within the spec:



Ratio of 2.5 = 1.5 BAR boost as i understand it.

 

If that is right then wow

 

good figures then

 

Wow indeed.
What is the spec of the heads, cams etc ?

 

Would be interesting to see which dyno this took place at! Mine did 600 on rcm rollers less than 2 bar but certainly not at 1.5 and you know what its like!

 

Certainly not a DD one Jag !

 

And who'd stop there ? If it does that at 1.5 what would it do at 2 bar, 700 on VPower ?

 

api has a dastek i think

 

Sounds like he is going to take your vpower record

 

More importantly what would it make on race fuel! Would be interesting if this were posted on 22b to see what the lads over there make of it!

 

Don't mind that....

I will upgrade to whatever he's got if I can get 647 @ such low'ish boost....makes your's, mine and other's look a tad "inefficient" on our 2.35s?

 

2.5? would that make a difference

 

Yeah, they don't like high boost or lbs

 

800bhp

 

 

Stage 4 heads with long duration cams and double valve springs.

 

It was on the API Impreza Dyno. I havnt picked it up yet so possibly the boost figure is wrong. I was previously running 2 bar on a smaller Turbo

 

whats stage 4 heads? just interested

 

It does have Darton liners like Oil Rig legs and forged, balanced almost everything on the power train, so hopefully it lasts a while.
