That amount of boost just blows me away! How are the motors able to take that?

I mean relating to springs and seals? Pistons engines get Titanium valves,super hard springs and retainers, decked and O ring heads just to deal with the increased PSI. Outside of Xdoweling,rotor pinning and housing oil bypass how do the stock spring and seals last........ or.......they dont?

Are there harder spring sets for the seal sets out there?

Kind of defeats the whole purpose of having a printed rule book, don't it? https://www.nopistons.com/forums/pub...1047683785.gif

I heard that Rafaelito used to run around 40psi on his old webber setup https://www.nopistons.com/forums/pub...IR#>/blink.png

yes the 800rwhp was made at 32 psi. The car has been up as high as 46psi and stayed together somebody turned the boost controller to high by accident and I got on the transbrake for about 9sec's according to my data log and when I reviewded it there she was higher then ever. Needless to say this year 32 psi will be the low setting https://www.nopistons.com/forums/pub...IR#>/smile.png
