footbrake racers

We talked to our long time trans man and racer told me I was to bring it up as far as it will go to lock the converter up all the way. Then he would let it drop back down in rpm. He said the object was to use the sling shot affect as the lights were coming down the RPMs were going back up. He also said this is not for bracket racing just for his best E.T. ever. I just put the pedal to the metal!!!
