Just wondering what the max bhp on a T34 is,that it can sit at comfortbly and at what stage do ya upgrade it? and to what turbo for next step?

 

Upgrade ya car before you spend THOUSANDS on it.
Nah joking aside i think there good for 360ish?

 

.63 housing probs 380-400 bhp,after that a t38 or t4,or go the gt turbo route.

 

do a search mate (top of the screen)......t34's come in different forms......

 

I,d say for reliability around 360-380 on a T34.63

Your next step as said maybe a T38, this is capable of 440-460

But another option is a GT3071, this again 450 turbo..

 

is a T35 just a T34 with a 0.63 housing?? or a different turbo all together??

 

same

 

Got T34 on it dont know what housing its on like, want to get car faster just dont want to ring the neck out of the turbo,its been live mapped at between 350-370 bhp so think it might be on its limit now at 1.6 bar so think it might be new turbo

 

Is that peaking @ 1.6 bar?? 370 seems alot for that..

 

see the thing is u could run 2bar through it with no problems, people have and do....but it could shit itself aswell.............(i'm not helping am i......)

 

Twat Pedro..

I was going to tell him this too...

 

You are NOT making that power on a T34!!!

run it at 2 bar and you will be though

I just bought a brand new T34.63 yesterday for my Westy.... was almost a grand!! OUCH!

but it will be running 2bar on an MSD chip and make around 380bhp and make my little Westfield SOOOO FOOOOOKING FAST!!!

can't wait, PROPERLY excited!

 

....change ur sig then.........

 

I want a spare on the shelf....

run them at 2bar and they can be unreliable.... ACCORDING TO YOU!

 

mines hold's 30 psi and peaks at 34.2 psi so you should have no problems with that power

 

My old 3dr is still running Lee @ 32 psi holding 28 and that,s near on 2 yrs now..

That,'ll be proper mental in the Westy..

 

It does depend on what exhaust housing you have.

You can get 3 different sizes, .48, .55 and .63, you will get the most power out of the .63.

T34 with .55 housing

 

Just had my car rollered and it made 325.5 BHP 312 FT/LBS torque @21 psi max boost, T34.48

A bit disappointed


Luciano

 

....maybe just a "real" figure.............

 

Surely to be expected with only 21psi boost? I'd have guessed around 330bhp...

 

sounds spot on!

 

T35 is a DIESEL turbo



T34 comes with several housings

they include

.48
.55
.63


remember a T34 is always a T34 regardless of the rear housing


a T35 is a DIESEL turbo

 

i very much doubt it is making that power with only 1.6 bar!

as said, exhaust housings come in .48, .55 & .63

i had a t34.55 and i ran 2 bar (peak) and hold 1.8 bar, so providing its in decent condition to begin with, 1.6 bar is piss easy, 2 bar is common.

i´ve seen as much as 2.2bar ran through a t34.63, but how long it will last is another story

 

the t34 on my cars got a .55 housing and has seen 353bhp with 323lb/ft tourqe at 20 psi on the dyno

 

You arent making 350 let alone 370bhp at 1.6 bar

Charlie - get some PROPER boost ffs

Porkie - T34 becomes unrelaible with 36 psi spike and 2 bar held

 

i've got a t34 .63 exhaust and cutbackblades on it. Does the cutback do any good, or just cutting back in power?
should have a proper remap to know what the engine does

 

Will cut power

 

hmmm, thats a downer. i want more . What reasons are there to put a cutbackblade type on a engine? ( i'm not in touch with the former owner anymore to ask)

 

cut back blades are to help spool up are they not?

 

my old 3 door made 402bhp on a .55 t35, its upto you to decide if thats bollox or not

 

To be honest think if ya read what a put a said it was live mapped at BETWEEN 350-370 a neva once said it was running 370 bhp. In response to staffi it peaks about 1.9 and backs off at bout and holds 1.6 bar wiv a safety cut off at 30psi mate.which was all done wen it was live mapped

 

Nope... they do the opposite!

their aim is to stop overspeeding of the Turbo...

 

I wouldn't have thought so considering they reduce the effectiveness of the turbine wheel

 

exactly what i had - but then be prepared to change the turbo at almost every service

i went through 4 in the 5 years my car was on the road

 

race fuel?

 

mine was 410bhp and 406 lb/ft on t34 0.63 but the engine obviously had other mods too

 

on stardard pump fuel - optimax.

 

Rubbish, it cuts response but improves air flow.

 

Just consumeables then.
