What boost at what RPM

Postby Jur on Sat Jan 04, 2003 12:41 am

I've changed my actuator to give peak 0.75 bar (sorry .. don't know the psi value)

But what boost does the engine normally generate at what RPM
considering the engine is as standard and Turbo is a standard T02 and the actuator is setup like mine to peak at 0.75 bar

I'm suspecting my actuator doesn't hold boost.

im guessing that it would peak at about 3500rpm then drop 2 or 3psi by 5000rpm
i havent driven a standard RS for 3 years so cant remember exactly
0.75 bar comes to 11psi, sounds like actuator is an uprated one
you should have a chip for that amount of boost
hope this helps

I don't know if it's an uprated one.. for all i know it's a standard one screwed up a bit to peak around 0.75 bar.

And of course it's chipped with this boost .. i use a superchip 165 (sorry .. didn't mention it.. but it's in my siggy right now)

so .. will peak aroung 3500.. and will drop around 5000.. ok .. sounds like mine is doing the same..

I'll take it on a rolling road this spring .. to fine-tune the engine.... so then i can tell my exact power.. last time (it was standard) my (now replaced) actuator was leaking .. but still gave 132BHP.. but the torque was a wee bit on the low side... but then again .. it was standard... so no real fuzz..

now it's tuned all over a bit.. so i'm curious what is does on the rolling road..

i'll let u know what the results will be (-:
