Wot u thoughts pros and cons on st3 saff 4x4
Thanks in advance

 

a t34 is a nice turbo for a road 330bhp

 

T34 = great spool, 400bhp potential and will bolt onto a std motor, cheap

T38 = slightly laggy in comparison but bigger top end hit , 480?bhp potential but will surge like hell unless you have a ported head, expensive

 

From what i know theres a few ppl who do there own kind off t38.

I had a T34 and found it ran out of puff about 6000rpm but my T38 pulls like a train i would never look back

 

Wot hp u running though pete standard engine?

 

There is the Universal Turbo's T38 that is based on a T34 frame with machined housings etc, meant to be good for approx 440ish with almost T34 spool-up

then there is the Turbo Technics T38 that is a T4 frame but slightly smaller housing a/r's and wheels etc. Meant to be good for 470ish approx with bit better than T4 spool-up.

Unless you want to push a genuine 400BHP +, and have the headwork to cope with it then stick to a T34.48

 

Is ur's turbo technics?

 

Nope UT

 

how do you mean

 

it will create more air than the engine can consume, so will cause back pressure to be felt by the compressor, and you get a horrid situation of the turbo speeding up and slowing down very quickly.

 

thanks for the explanation

 

Have to agree, i've had both UT T38 and a T34.48 and i must say the latter was awesome for a road car, peaking @ 32 psi it spooled up fantastic, where as the 38 was laggy in comparison..

 

Thanks 4 advise chaps stick with the 34 then

 

I have a UT T38 on my car just now im just running in so set to 12 psi max, its making posative boost around 2200 rpm and 12psi before 3000rpm.
