That sounds plausible. Thanks!

Mr. GMoney....would you like to enlighten me as to what the proper launch technique is....it seems as though years of engineering studies and automotive technology design classes have not hightened my understanding of automobiles....perhaps the professionals are wrong and Mr.GMoney is right!

Cheers,

Kamil

P.S. i wouldn't sell you my tip if i had one!

I have no idea what the best technique is. The post was to be taken lightly, humerous even.

For the record years of engineering studies and automotive technology did not dictate the power brake launch technique, its been around for a while, as in since torque converters / slush boxes were being installed in cars.

I don't think you want to tell me that understanding how automobiles work and engineering have nothing in common....Anyways, i'm assured it was humorous and so, no offense taken..

Cheers,

Kamil

jlee, Kamil is correct. Putting the car in neutral allows you to apply more brake pressue thus allowing the car to stay put so you can build boost and take off HARD. Try it both ways and you will see what I mean. Without the quick stab in neutral and more brake pressure the car (at lest mine) will creep foreward long before boost is built = slow take off's. With the neutral, more brake pressure deal it = FAST take off's like a bat out of hell I tell ya.
Good luck. Oh..... my tip. is not for sell.

A quick google search:

If your car has power brakes, you could apply the brake-torquing technique even better. At the starting line, shift your auto gearbox into neutral and floor the brake pedal with your left foot. Rev the engine once and quickly get off the throttle. You will feel the brake pedal sink further to the floor. This greatly increases the braking force. Now shift back into gear. You will now be able to rev up the engine even higher against the torque converter.

I'd imagine it's because the power brakes work with vacuum, and the engne will create more vacuum at decel than at idle.
