No, I do not Just dump it. I try to keep a little pressure on the clutch so the car does not pull to the right and just spin right off the line. I am going to start launching around 4800-5000 rpm when I get a new set of yokohama prada spec 2. But I need some more practice, I only have about 15 or 16 passes down the 1/4 mile
