Keep in mind this is a brain that has been down the track maybe 10 times.
A while back there was a video of slow motion drag cars starting at the line. The hole way the tire would slip little by little. I know the clutch slips off the line also. This lets the engine rev and make power without the bogg.
If the tires did not slip any then the engine would lose power because of the loss of motion in the tires.
With the tires spinning the engine operates at the most power. Tires not spinning the engine has more load on it and will lower power until the rpms catch back up.
I would think the spin also makes more torque like a lower gear would.

No spin gets you out of the hole very quick but may bogg the motor some after the 60 ft.

My head hurts more now than before I had to get up for drugs.

I just have to add this, How much tire slippage does it take to acheive maxium accelateration, traction???

Slipping the clutch you can make more power and faster times starting out of the hole. I do anyway. I would think the same would be for tires getting power to the ground.
If everything hooked up, something would break or bogg.

Now I am going back to my autocross that I'm not much better at.

Another example, from 5.0 of MM&FF, was earlier last year on a shakedown run Tim Lynch at E-town ran a 6.6ish at 215mph, then on another pass went a 6.8ish 223mph and the article said it was due to tire spin off the line.

My question for everyone is back in november i saw a 03 cobra at steele that has the same mods at me. His 1st run was a 10.4 at 132 sideways with the backend almost on the wall the entire 1/4/ then he hooked real hard & didn't spin at all & ran a 10.3 at 132. He was on slicks & skinnies. I'm just tryign to learn as much as i can here so lets keep this goin.

was that car burgandy?
