my car is going under major changes in Aug big turbo, big cams and a standalone, but i want it running at peak power for the time being, so if you guys could tell me what i should set my boost at it is at (20psi) now but after the O2 housing i might have to change it.

 

you should ask Al. I think he recommands 20 psi for his flashed car on 91 oct.

 

20 sounds about right

 

My car spikes to 22 and drops to 19 by redline 91 oct.

 

The IX's are doing like 22-24lbs on 91. Apparently we have a higher knock threshold thanks to revised coolant passages.


The VIII's are doing around 20-21lbs on 91.

 

thanks for the input i have it set at twenty now it will drop to 18 somtimes i just want to get the most power out of that crap gas as i can

 

22 peak will be fine.

 

when you guys say peak, do you mean the pressure it reads during the boost spike or maximum boost the turbo holds before tapering down?

 

This will also depend on timing. I'm assuming your talking about a stock ecu?

 

well it is a flashed stock ecu, mail in flash.. so you think i could dial in my boost controller to 22 and let is taper to 20 on 91?
