If you or someone you know of is boosting with either turbo or s/c on pump gas, how much boost are you/they running and what kind of numbers are you/they getting?

Over at turbo mustangs they say 8-10 psi should be fine, but I'm sure there are many over that level of boost... what do you have to do to run more boost on a daily driver?

You would need a good timing controller (preferably) PMS or TwEECer, as the MSD boost reatrd is not accurate. A good tune, and 93 Octane. I have a firend that puts down 500+ RWHP on 93. IN his race tune on his PMS he makes 625RWHP. I'm not sure if that is with race gas or not.

This should be in talk, and ive seen 17 psi on pump gas on turbo cars. My combo makes 554 rwhp with the stock block ,and im currently having a race block motor build, which will be pumping out at least 600rwhp with about 12 psi
