There is no set psi. There is set # of degrees. IIRC it's around 15degrees Let me go search.

according to msd's site it is 15 degrees http://store.summitracing.com/...-8762

at 16 psi...with .5* retard per psi...that is a total of 8 degrees minus the total timing of 28 degrees. with 20 degrees, that is definatley enough timing, if not more timing than needed. you should probably even retard some a little base timing. i say base timing because at 16psi...with .75* per psi is quite a lot. unless you move it up slightly over .5
