I'm running 40-45 psi with my timing to the head. If that helps you.

 

i ran +1 tooth, the timing spacer, 42 psi i think, and stock bolts untorqued for a few months last year.

 

Was just curious, the s300 does 35 with ease, was going to get an adjustable elbow and get it up to 40-42. I think I'd be happy there. I don't believe it'd be out of the s300's efficiency range, just no map to consult.
