I was wondering how much boost i should be running at stage 3?
I have an rs500 intercooler and a t35 .63. when i had it set up it was just after the engine was rebuilt so they said I could turn it up after I had done 3000 miles but never did.
What should it be ?its at 19psi at the moment

 

Think most stage 3 setups run 21-22psi, so you're not far off now. What injectors have you got? they'll be the limiting factor.

 

depends on what the chip has been speced for

 

We're running 25 peak, 22 held on our 2wd with a T34, greens and a 4x4 intercooler. Assuming your injectors are up to the job (and the fuel pump and rewired), you should be able to put a little more boost through seeing that you have an RS500 intercooler.

I asked Mark (MAD) to set it up on the safe side, was done in July on a hot day and we were getting early signs of det with a touch more boost than that so he wound the boost down, and a little more

Make sure you get someone in the know to set it up for you as you want it

 

Don't tamper, get it on the rollers for a setup, just to be safe.
