Default New setup: Tire pressure and launch RPM?

Over this never ending winter I've had UPR uca/lca's with spherical bushings, a Baseline ARB, and Steeda FLSFC's installed. I also put an MSD 2 step in last weekend and have a set of M/T 315/35-17's sitting in the garage. What tire pressure and launch RPM would you guys recommend using? I'm thinking 18psi and 4000rpm is a decent point to start from, but I'm not sure.

That sounds good....you are probably going to bog with 315 dr's and a 4000rpm launch but who knows. Just start from where you are at and slowly move down....there are tons of variables that only you can feel out when you are on the track

15-17 psi
Start with a 3k launch and go from there

Pray for decent track prep, without it there's nothing you can do to get a DR to hook.

And that is why I'll never have DR's on a stick car again. They seem to work much better with Auto's.

Atco's pretty good, especially on gambler's nights, that's usually when I go.
