How high Rpm should I launch

Hey guys I'm wondering with my new tire set up what rpm I should launch at the track? My first and only track time was in October and I could only manage a 60' time if 2.14, 1/8 of 9.5, and 1/4 of 14.6@97mph. This was with my 2002 GT very 5 SPF with the following done.

1. Mac LT, prochamber, and SLP LM1 weld ins
2. JLT ram air intake.
3. Steeda springs. MM sf connectors, tokico blues
4. Stock 3.27 gears and Crappy Nexen all season CP672 245/45/17.

Only new mods now are the massive 315/35-17 Nitto 555 (non DR), 3:73 gears, and a SR performance plenum and some lightweight front seats.

Basically I want to try to get sub 2 second 60' times and get into the 13s when I take it to the track in March. At the same time I don't want to kill my TR3650 or the other than gears stock 8.8. So what Rpm should I launch at? I was going at about 2k and slipping the clutch so as now to spin too much, but also to not kill the tranny. Also what tire pressure should I run the rear an frońts. I'll probably do a short 2nd gear burnout just to get them clean and a little stickier. Thanks.

For my 03 gt it depends on the days temperature, and the surface your doing it on. but for my car, I usually do it around 2.75k or 3k. (i have 245 nitto nt555 in the back as well) But you have to remember that every car is different. So you have to find the sweet spot, to where it wont bog down, and it wont burn out too much. good luck man.

I have the subframe connectors and a MGW shifter, but yes will need to slam the gears a little better. I went with 373 since most of my driving is highway (and yes I know the debate rages on to the day of 373 vs 410). I will put some MM LCAs on later this summer and look into differ stirs and shocks. Skiinies would be nice for the track but why should I remove the front sway bar? I've heard this before, just didn't know why? Thanks for the launching rpm tip I'll try a few diff spots. What about tire PSI? 20-22 for rear 315's?

Ohh gotcha...wouldn't think that since it weighs maybe 5lbs, but probably due to the rigidity then.

My car was a 3.8 up until 2012 when I swapped it over. They are the Autometer Lunar series for a V6 (120mph spedo 7K tach), but they do the job just fine.
