High boost is a lot less stress than with low boost and nos.crispeed

i run 20psi on pump gas. i have gone over as much as 1.6 bar on pump because of weird boost creep that just randomly occurs... not that my motor is actually liking that kidna boost especially with a 2 bar map sensor(oops!)... i guess my timing must be way back or i am one lucky mf'er.

Who's got the most psi using pump gas and water injection ?? , and has anyone tried to directly introduce "RAW" octane booster , using a WI type system, how'd it work ? .

Crispeed: Don't ask why but I thought you ran alcohol.....Now I'm even more impressed
As I've said before, as long as your timing is dialed in 20psi isn't hard to get out of a rotary...Thats one of the main ingredients

Come to think of it, I've run 26psi on my TO4. This was not intentional(setting up my boost controller), and it was on 103 octane with very conservative timing, and af ratios around 10:1. I've run 23 psi autocrossing several times with no problems. Ignition is 3-msd6a, NGK race plugs,stock FC coils. Carl Byck
