Re: Went drag racing - major break down
I did stick shift drag racing for several years, using a T56/LS combo in a 3500lb raceweight Camaro running high 10's.
I broke enough parts I think I actually learned a few things!
1) Tires are everything. A stiff wall slick (MT3055S 28" slickis what I used) is the main component to keeping parts alive. Drag radials are brutal on the drivetrain.
2) The posi won't last. I had to go to a spool early. But that twisted the axle splines, so had to upgrade from 31 to 35 spline axles. Problem fixed.
3) Don't fear the gear! Went from 4.11, broke that. 4.30, broke that, then finally a 4.56. The 4.56 worked so much better and was so much less violent on the launch.
4) Suspension bushings need to be "solid". Maybe not rod ends, but certainly not rubber. I actually broke suspension parts and bushings wore, causing a yaw moment in the rear end at launch. Put things in a bad position.
5) Don't dead hook. A good stick shift launch should turn the tires a couple of revolutions as it moves forward. This keeps the engine RPM up and the car moving. And unlike a Drag Radial that doesn't recover while spinning, a slick will. I usually had 1.45-1.47 60' times one the car was dialed in.
