From a roll: M6 or Stalled auto?

I ran a mild cammed TA M6 with my Z28 A4. We both had all bolt ons and free mods. He had the cam and I have a PTC 3500 stall. My fastest track time was a 12.3 @ 110mph with a 1.68 60ft. He ran right about the same but his 60ft. was around 1.98 and trap speed was around 115. I beat him from a dig 2 times in a row. We went from a 45mph roll and he would walk me every time by about 1- 1 1/2 cars to about 120mph..

The key is the stall and the more power that the 2 cars put down the worse the beating will be for the stick car. The key is getting that stall to flash around 4000-4500. It will be lights out at any roll speed for an equally powered 6 speed.

please explain why a device that, inherently by design, eats more power as it makes its way to the tires (don't good converters have a max efficiency of around 90%?) can pull a car putting more power to the ground in a purely roll racing situation? I could see taking a jump on the hit when it flashes (ie getting into the powerband faster), but after that its just robbing power and I would suspect the 6 speed car would come inching by given enough room.

The only thing I could possibly think is the shift extension holding right in it's power while the M6 moves through it. I don't know how far an M6 drops with each shift though.

Ok. That makes sense. I only dynoed 313 the other day with full bolt-ons 
. My graphs looked funny though... I still wonder what was up.

My car made 335rwhp (it made 309 stock with exhaust and a lid and ran 13.6 @104mph) with all bolt ons and free mods with a PTC 3500 stall and I had trouble breaking 12.3 run. You just have to find that sweet spot to leave on.. The same night I ran 12.6 @ 108mph, 3 times in a row. Then a friend of mine that has a 95 ss that is fully built for the track ran my car and it went 12.48. I ask him what he did to get it to run faster. I was stalling the car to about 2200rpm and leaving it in drive. He said he was able to stall it up to about 2800rpm and was shifting the car himself.. I tried the same thing and thats when I ran the 12.32 @110.2 mph
