m6 launch, tire spin vs feathering clutch? Should net same 60ft times without bogging
Alright my best m6 60ft time dumping the clutch was 1.57 on ET streets(non-radial) last night but I bogged after not having any wheel spin(I might add tire pressure next time). Anyhow I kept reading people say to keep from bogging you need a little tire spin(add tire pressure) and others said to feather the clutch. I think they should net the same 60ft times without bogging using both methods.
Think about it both methods keep the rpms up to keep from bogging. Dumping the clutch w/ some wheel spin method will keep the power to the wheels, but have just enough spin to keep the rpms up. Feathering the clutch method you lose power to the wheels, but keep the rpms up since you aren't dumping the clutch on tires that you could not get to slip. Except the feathering method will burn your clutch out faster. Is this not correct?
Also do you think if I up my tire pressure to get a little wheel spin I can still get a 1.57 60ft but not bog?

I'm an auto guy so I can only guess. I'd say you would be better off with a little more air pressure and a few revolutions of wheel spin. Seems to me it would be easier to have more consistent launches if you dumped the clutch at a certain rpm every time your at the line. Of coarse the track could change and you'll have to adjust, but that's just part of the game.

Unless you have an adjustable clutch to control clutch slip, you need to spin the tire.
Like he said, feathering the clutch in a quick car is a crap shoot and very inconsistant.
Use the 2 step feature on your 685 Mallory to control rpm's while the clutch is depressed.
I think you need consistant launch procedure before you can go about trial and error with air pressure, shock settings, and rpms. Goodluck!

Launch higher.
Feathering a stock-style clutch on a high-rpm launch with a sticky tire will eat the clutch and be very inconsistent (as stated above). Launch higher, instead.
Put as much gear in the rear as you can stand. And launch higher.
Good luck.
