I'm not a newbie to the track, but I imagine running a rwd is just a tiny bit different. :)

What tire pressures/shock and strut settings am i looking at? I'm worried about that 3 bolt snapping, how do I avoid that? What do I look for to make sure the car doesn't break? For shifting rpms, I plan on 7200 in 1st, 7000 in 2nd, 6800 in 3rd...are these alright?

Any tips or tricks you can give me? What about launching technique?

Car will be full interior, also. any benchracing for what the car should be capable of?

Thank you for your help!
 
Well, I went to the track. First run I had the AGX's set at 1 in the front, and 3 in the rear. Full weight, 35 psi in all 4 tires. I launched at 4.8k and slipped. The 60 foot was only a 2.100, and I ended up running a 14.8 at 94. The car fell flat on its face in 3rd. Never even got into 4th.

I let the car cooldown, looked over the log for the run and saw that I had no knock, and injectors were at 19.7ms up top. So I leaned the AFC out 4% from 4k up. Deflated tires to 28 psi all around, put rear AGX's to 1. Launched at 5.5k, cut a 1.91 60 foot with no spin. 3rd gear felt better, but still fell on its face aound 6.4k, so I shifted into 4th and finished the run. Ran a 14.2 at 96mph.

Checked the logger and the pda screen died, so I have no idea if the 4% gave me any knock or not. Gained 2mph, and dropped 6 tenths, so that's good, but the trap speed for 18psi on a 14b on pump gas is kinda low for my mods, I'm thinking. I think that I'm running really rich, but I don't know until I go again with a new pda.

Any recommendations or ideas? Boost starts to fall off at the top of 3rd from 18 to 15/16 psi, then I shift to 4th.
