I will agree there. I was running 19 PSI with the usuall chip, exhaust, filter and -31. The only thing that kept letting go was the clutch. The rest was standard.

would any of you believe me if i told you my mates S2 1.6 made 230bhp on totd rollers a few months ago and that was on a std turbo peaking @ 18psi! without nos![/QUOTE]

Yeah i'd believe you...don't know whether or not i'd believe the rolling road tho lol! Don't take alot of notice of them anymore, seem to chuck out such varied results it's unreal so tend to go on performance of the car now rather than just rr figures. For example i had mine rolling roaded at one place where it made a dismal 199bhp and directly after a mates mi16 pug on jenvey's etc etc made 145 bhp pmsl! Now i know for a fact there's no way those figures are anything like true.......

std t3 will hold 15psi easy,how long no one knows,but it wont flow the same air as an uprated one would so expect a drop in horsepower,not by much i would reckon

i got 157BHP at 15 psi and 168 at 19psi on a std T3 so it must flow ok

B16CVH

Back in the day, i had a 1.6CVH running a standard T3, made 200bhp (at Interpro) and 222lb/ft holding 15psi all the way to the redline.

adam.d

Well I had mine on the rollers and it made 197 bhp hitting 18psi and holding 15psi. I've now put my origional turbo in to be reconned with 360 deg thrust bearing. I asked the question because I don't know what spec my turbo is and it needed replacing. I didn't want to loose any power by buying a standard turbo if mine was stage 2, if that makes sense!

JamboRS

and thats ur back up to prove it must flow ok,,yeah i can see how 11bhp form 4psi of boost is really flowin well lol

is evey one running 360 bearing over 14psi.also i would say 18psi top's
no point running more as the comp trim is out of it's comp map and just heat up
air temp plus the small .36 turbine housing is restrictive and wount flow the air
go for a .49 housing

well it flowed more didnt it,not less

mikemcc03

are you saying a standard erst T3 turbo has .36 housing? im not having a go or anything im only sayin because when i looked at my 2 i think standard turbo's they both said .42 on them so are my turbos standard or not?

JamboRS

has it,11 bhp from 4psi is really flowin well,ull be well onto 200bhp with a gazillion psi of boost lol

seriously mate 11bhp from 4psi is not something id risk on a std turbo,is 10bhp more important than a reliable motor,do u think cos u can squeeze more boost out it its flowin better

oh forgot to add,was on std intercooler to
was a few years back mind...he finnished with 168 at 16 psi,keep me happy for a few weeks,

i'am talking about the exhaust housing side mate

IIRC exhuast is 36 and compressor is 42 on a stock T3.

ah ok thanks..

Lets get this thread up again. I will map my erst next week and wondering how much boost i put. Now there is 13psi (0.9bar) max boost. I have totally standard T03 with .36 exhaust and .42 kompressor housings. Where goes std turbo limit that boost raising wouldnt give more power? I have been thinking something like 15 psi. I have bigger ic and mappable efi managment too. I must have reliable setup, because i cannot afford new turbo in this summer i think. Have you looked your exhaust manifolds and exhaust housings after driving hard? Mine std turbo glows red even 10psi..

Depends 100% on what cam you are running, what port work your head has done, what exhaust you have etc.. the engines Volumetric Efficiency.
If you are on a standard head, standard cam, etc. then maybe 16/17psi.
If you have for example a big valve head, big ports, Piper 285T2 (or any very high profile cam) etc. then maybe only 10/11psi, you will peek higher midrange but not hold it, and if you force it to hold using a EBC then the turbo will not last long at all, and you'll just generate a lot of heat and no extra power.

The easier your engine can get the gasses in and out the less resistance it will put up (less boost pressure will register) to make your target BHP, the harder it is the more resistance (more boost pressure) to make the same target BHP.

If your manifold is glowing at only 10psi then perhaps you are lean or your timing is retarded too much.

Antti O

I have ported efi head, 285t2 cam timed properly. Matched inlet and exhaust manifold, pipercross big filter and 2.5" mongoose exhaust system.

standard ERST T3 18psi peak. i run 12psi through mine,cuz i have a few mods,and it boosts up fine at 2k and holds power all the way through the range.its obvious the more power u run through it the less time its going to last,as its a standard item,some of you boys runnin 20psi thru em or even 16psi without a intercooler,are playin a risky game with your engine.also one of the reasons i run 12psi as no ic yet.
