What do you mean by preloading the drivetrain? My car always seems to move when I let the clutch out. :screwy: What do you guys do on BFG's?pauls said:Rich you bought some real slicks in BG, didn't you? If you have M/Ts it should be no problem getting 60s. Get the good half shafts and preload the drive train with the clutch in the staging lights. That takes the slack out of the driveline and will save your shafts. Then wind her up like Wayne says. My best sixty was on the rev limiter at BG. But for some practical life of components plan on about 4800. Air the tires so their just turning over slightly (16psi for me). You don't want them to dead hook and bog the engine down. You have to be able to drive through the tires and clutch in first gear to get your best 60.

What he means is let the clutch out till it just barely 'grabs' something, I.E. the drivetrain. The clutch should be engaged enough to stop a car from rolling backwards-if someone were to push on it from the front (much the same as you would do while starting off going up a hill), but NOT enough to make the car go forward.BigCarrot said:What do you mean by preloading the drivetrain?

Great info! Doing this have you accidentally rolled forward a tad and red lighted? How far forward does one need to go to redlight?ROLLMODEL said:What he means is let the clutch out till it just barely 'grabs' something, I.E. the drivetrain.

Much like an auto it 'loads' the driveline much more, although not NEARLY as much. This keeps the tires from getting shocked on the launch, providing more initial bite, and helps out the longevity of driveline components.
