12-15 PSI is a good range to stop at.

the blown jspec engine i had was hitting 15psi..... it won't last long at the pressure but the car should be pretty fast https://www.nopistons.com/forums/pub...IR#>/smile.png

Yeah, 12-13 PSI is a good limit, but you'll need the "appropriate" mods.

my car has the mods it needs to run high boost on a small turbo...... just waiting to get turborotor's turbo and swap them. i might be swapping back to the stock radiator. the car runs to hot with the griffin with no shroud. so my griffin might be for sale soon https://www.nopistons.com/forums/pub...DIR#>/wink.png

On a related note... what is the full scale reading on the stock boost gauge in PSI? I think the factory gauge reads mm of mercury? I notice my gauge gets pretty much all the way up when I dog it. I was wondering where it'll end up when I free up my exhaust.

400 mm of Hg is about 7.6 PSI.

It's actually 7.7 PSI at 32 degrees F. http://www.megaconverter.com/Mega2/index.html is a good site for stuff like that.

Cool. Thanks! :bigok:

You're welcome.
