Unbelievable.
nlzmo400r, I'm sure you mean well, but you can't say which puts more stress on a driveline without doing test after test. Cars are DESIGNED to be accelerated rapidly from a dead stop. Cars are NOT designed to be "powerbraked".
Here's the deal - Powerbraking an automatic has more to do with getting the car into it's powerband. For example: My Q has 278 hp. It's fast. And it's peak power is developed somewhere between 4-6K rpms. So off the line, it'll get eaten alive by a car with more bottom end power. So, by powerbraking, I get the car deeper into it's "sweet spot" (engine is already revving higher).
Big problem? Wheelspin. IF I can manaage to get the car to sit still at 2000 rpm's preparing to launch (usually it'll start spinning the rears), then even when I DO launch, I'm sitting in a cloud of my own back tires - TOO much power off the line.
R&T did a test a few years back wherein they observed 60' times for a few popular vehicles. Times were NOT significantly better for the "powerbraked" cars.
I'd prefer to get a good, solid launch, feathering the throttle to minimize wheelspin and take my chances on passing the poor unsuspecting basturd at around 45-50 mph...
Neutral drops are just plain retarded and anyone doing it should be forced to drive a Hyundai Scoupe with a misfiring #3 cylinder and white-letter tires for the rest of their life.
