I'll be taken the beast to the drag strip on the 28th for the first time ever. I really need your inputs on what i should do and dont do!
I have put on a brand new set of BFGoodrich Drag radials, got all the bugs sorted out and will be running on racing fuel!
So.. the question is...
1.How to launch? What RPM and whether to pop the clutch or ease off?
2. When to floor it?
3. Shoudl I power shift or not?
4. Stick trackbite is gonna make a bog difference to traction?
5. Should i warm the tires up on the water box?
and any other tips would be appreacited!
I have seen vette C6's pop their differential, and drag cars break shafts etc etc... its the last thing i want to happen to the ///M!!!

1.How to launch? What RPM and whether to pop the clutch or ease off?
I think the best with stock tires is at or just above 1K rpm. With drag radials, you can launch at higher rpm. However, I wouldn't go to 4K rpm or you risk trearing up your rear or other damage. It's a delicate balance of not frying the clutch and getting good traction.
2. When to floor it?
On other cars (I haven't tracked the M yet) I've always genlty floored it right out of the hole while slipping the clutch a bit. Others will tell you differently.
3. Should I power shift or not?
I always use the clutch and make quick shifts by poping out the clutch very quickly. It's a quick 'stab' at the clutch. Just don't miss the gear and over rev the engine.
4. Stick trackbite is gonna make a bog difference to traction?
Probably but you must be careful. Too much bite will tear your car up.
5. Should i warm the tires up on the water box?
Stock tires = No. Drag radials/Slicks = Yes.

Take it easy on the first pass to get accustomed to the procedure. Don't ever worry about the guy next to you. Don't ever worry about the reaction time...it means nothing. You are trying to get your best time, not race the guy next to you. If you are comfortable by letting him get down the track 500ft. before you launch, then do so. Your 60' time is critical to a good 1/4 mile time. Every 1/10th you shave off the launch (60' time), you shave 2/10th's off the 1/4 mile.
Oh, and you'll need a helmet.

racing fuel doesn't equate with more power in most cases
Unocal 100 seemed to be an improvement but worked best when
blended with 1/2 of a premium 91-22 gas. Unocal 100 made for
better throttle response and only slightly greater peak power
I tried 104 octane and the car did not feel nearly as fast
