Do not slip the clutch you will burn it out in 1 run, four and a half k is a good starting point hold it there left foot off like a switch and your off on yellow, if it dies take the revs higher next time if it bogs down let some air out of your tires 25-26 psi works good{tyres stand up on launch and doesnt cause too much drag} good luck its addictive and more expensive than drugs.
