Drag Launch Techniques for 512whp C6 M6
I was hoping for tips and techniques on launching. I can't get this car down the track without breaking or the clutch pedal sticking. I've broke the rear case, output shaft, two half shafts and the bellhousing, I made some changes and now ready to test & tune. I swapped the drag radials for MT streets, lightened the car 200 lbs and put a remote bleeder for clutch valve.
CARTEK TUNE
Drag radial runs.
Half dozen runs with severe wheel hop and breaking parts.
QA1 Adjustable shocks eliminated wheel hop.
Best ET 11.04 @ 130.41 mph 1.75 60 ft 3500 rpm launch.
2nd ET 11.14 @ 131.00 mph 1.78 60 ft 3200 rpm launch.
3rd ET ? 1.57 60 ft 4100 rpm launch clutch pedal stock 3rd gear.
4th ET ? 1.54 60 ft 4200 rpm launch clutch pedal stock 2nd gear.
MT ET Street
200 lbs lighter
No track time yet. Thanks

I posted a reply suggesting you go to an automatic, I think it would be best for a high HP car that is breaking parts..I also had some other suggestions that were from VERY knowledge sorses... But some here "Think" they know MORE than race shops. & deleted my post last night...
Really pizzz me off.. not even a PM explaining WHY... Maybe he knows more than the NJ Tuner shops??
Did Some Moderator remove my reply without the courtesy of notifying me

you sound like you're doing what i would be doing, are you side stepping, popping or easing off like your taking off normal from a stop? i would try the latter as it will maintain traction and is easier on your drive train, on the shifts maybe slow the clutch release to be easier on eevrything.
How i launch:
1) get up to an rpm (depends on power/ tire)
2) let off clutch as if your just at a stop light only faster, adding gas to keep the rpms constant to the value in step 1
3) keep increasing the rpm in 1, and the rate of release in 2 until you spin
4) if you spin initially your rpm in 1 is too high
5) if you spin a second or two after moving your rate in 2 is to fast
6) if you bog add rpm to step 1
it seems elementary but you cant run before you can crawl

I would like to put it on the Z06 topic. Does it matter if i'm running a C6 non Z06?
I decided to try the Nitto NT05 335/30ZR19'' street tire, it has a more forgiving sidewall and their similar to the Toyo R888 but not as sticky. I didn't think it was a good ideal to have the stiff sidewall with the wheel hop issue i was having. Thanks good advise
