Sorry Joe and FirestormTT, I was just being sarcastic because these guys ignored my advice. I stuck in the rolleyes smiley, but I apologize nonetheless.
If you'll read my first post in this thread, it tells all you need to know about launching. My launches stick so hard that the windshield wipers come on (no joke!). If you have drag radials, which I'm itching for badly, you can launch higher, but 3K is the highest I've been able to launch with 29psi in the Khumos. What's crazy is the more these tires wear the better they grip.
Shift at 7200-7300 rpms. DO NOT hit the rev limiter because it takes your fuel injection a split second to recoup from the fuel cut, and you lose a few horses (I learned this from a Super Street dyno of a Focus where they lost HP when they hit the rev limiter).
