Launching a 6-Speed LS1
Re: Launching a 6-Speed LS1 Aaron said he had a 12 bolt. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
I would not dump a 10 bolt more than 3,500 to 4,000 rpms. <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />

Re: Launching a 6-Speed LS1 This technique will get you good 60's and also save your drivetrain.
at the line rev the car to your desired launching rpm. (say 5000rpm)
When the third yellow lights up lift your foot straight up off the clutch as fast as you can while flooring the gas at the same time. (One fluid motion) This will load the drivetrain and greatly reduce the shock on parts. you will still cut great sixties with this technique. It takes a little while to get used to but works awesome.
Cheers,
Chris

Re: Launching a 6-Speed LS1 Aaron, I've broken a few parts just as well. Just a fact of racing. However, once you get where you are now it should be a lot more fun. I basically start with my tires a little hard and then work my way up the RPM's. When it begins to bite good then we work on the tire pressure. I'd rather blow the tires off the car than to bog the motor and driveline down. Less stressful.
Once you get a comfortable launch RPM, mine is currently 5000 to 5500 on 26" x 11.5" Hoosiers then you can work on dialing in the tire pressure a little better. It's just a lot of experimenting with launch RPM and pressure at this point! But if all this is too scientific, just bang her off the revlimiter and hold on! That works too, lol!

Launching a 6-Speed LS1 I have a 98 TA with complete BMR suspension and Hal Struts and Shock, exhaust (complete), 4.11 gear, Moser 12 bolt rear end, hypertech PP3, and E.T. Streets. How should I launch this thing? I keep breaking parts. Rear end, 2 BMR Torque arms (now have extreme duty torque arm) pinion angle is set at negative 2, and I've broken one driveshaft. How should I come out of the hole?
Re: Launching a 6-Speed LS1 Wow, Sorry for the bad luck. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
I have 196 6,500 rpm launches on my M6 Hot Rod and have not broke anything in the drive train. I had everything BMR has for our cars with no braking with 4.56 gear for 1/2 the season and now I have 5.13 gears with 30x9x15 slicks. I now have a Madman tq arm and solid motor mounts. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Start out with 4,500 rpms and work your way up. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Launching a 6-Speed LS1 What pinion angles are you guys running at with manuals? Right now it's set at negative 2.
I will see how it works this weekend at Morocco with the new BMR Xtreme duty torque arm it's much more solid than the other BMR trak pak torque arm.
