Default Is 14psi safe for 10:1 and 91 Octane?
Anyone running 10:1 and ~14psi on a supercharger setup on 91 octane.

My car is going to be my daily driver so I would like to know any long term reliability issues.

It is basically dependent on the tuning. I'm running a little more compression at about 10.4 to 1 and 13 psi with no ping. AEM tuning by Shawn Church.

if u take out a lot of timing, it might be

generally though, that sounds like too much boost for a 10:1 compression motor
