All depends on how much time you want to put into chassis set up. theres no one size fits all combo I could give you to work.
However I can tell you I've had 30psi on the street rammped in by 3rd gear. I'm sure I could of gone more but fear held me back from pushing further. You can get aggressive with ramp rates, and you'll be surprised to find that going plus or minus 5 May be the diffrence between blowing the tire off, or hooking and booking.
And if your setting up to do it from a roll always brake boost when figuring your base numbers. It's easier to combat wheel spin due to the rear shock already being loaded before more power gets added.
