8.5 PSI works for me

I'm running 8.5PSI with a Vortech V3 supercharger on a stock engine with a secondary control computer. Since it's a supercharger, that boost is only developed above 6000, so its not boosting that high during normal driving. My guess is that you can go at least that high, but insure you get it tuned properly.

Dude you have a built motor so yes you can turn the boost much higher then you are now...just remember to have it retuned before you mess with the boost settings.I am at 9 psi on a stock block so you have a ways to go.

Nothing but a turbonator.
