Im still new to all this rotary stuff and I have been looking around and still can find what I can run for psi.
How much can these motors handle with the right fuel set up and right motor work. Right now I have for fuel
Supra TT FP
850 prime
1600 seconds
Power FC
and the block is from pettit with street bore and 3mm
its got greddy tdo6 upgrades and other **** like exhaust to much to type right now. Its just a general question?

 

The limit is not PSI, the limit is your A/F ratio. Even with stock ports and stock seals, people have run WELL over 20 PSI on large single turbos.

 

your gonna need a big intercooler to go over 15psi safely i think.

 

Ok sounds good thanks
