Give it a try...can't hurt. My Willys responds much better to to a mash it and go rather than hold it against the brakes. The chassis and rear suspension gets loaded much better. I hold it at about 2000 and step on it. This is with only a 3000 converter and I see an almost instant 3500 before the car goes very far. It doesn't really spin the tires much this way either. If you hold it with the brakes it just blows the tires off. Can't wait to try it with the blower.

This is true w/torquey cars, in my experience. Or light, and/or traction-limited cars.

The last torquey engine I had was that 0.030 over Pontiac 455 in a 3750 lb. F-body, I left from an idle, matted it on the last yellow. It 60'ed at 1.7 seconds, so was hooking pretty good.

If I brought the RPM up against the brake, it would fry the skins.

On the other hand, if the engine has a ton of cam and lacks torque, you need to bring the R's up at launch, to as much as just under the torque peak if the TC will let you. A lot depends on the suspension, as well as tires, etc.

Ya, give it a try. Years back I ran a 68 Road Runner with a 440, tunnel ram, 4500 stall etc and it ran a 10.68 at max stall and a 10.69 leaving at an idle. The car was consistent either way so I always left at an idle and stalled it up if I thought I needed the extra .01
