I’ll even help you swap em over… meet at my house your house or the track plus slomarro going real soon saturday wont happen he didn’t put his car back together yet but maybe this coming wednesday or the next saturday. > > Launching, I’ve found it works pretty good to slightly engage the clutch at the sign of the first yellow light to put load on the drivetrain and then as you engage the clutch 1/3 of the way let rpms drop and start feathuring the throttle (giving more gas) after 1/3 thru engaging the clutch so you get going before the the tire have a chance to spin.:ohnoes Confusing yet simple.:eek > > RPM’s : using that procedure find the highest rpms you can start at with out kicking your car sideways. spinning them for a 1/2 sec on launch is a necessary evil on street tires, drag radial that wont happen though. I would just swap them there. I would like to see what I can get on street tires and then drag radials and swap back over to streets for the way home…I wont be able to get out there prolly until a few wensdays from now… also that clutch thing…Im not sure if you are familier with the ram powergrip clutch’s but my clutch is a bitch. It engages fully if you just tap the damn thing, and if you try to feather it…it heats up and grabs harder and harder and usually chatters. It was designed to where the hotter it gets, the harder it grabs and I havent found that happy medium yet when launching. --- _[View the full topic](https://forums.speedlife.net/t/the-official-callout-kill-thread/244455)._
