Seems most in this thread haven't figured it out yet, doesn't have to be as hard or expensive as it may seem.

Under about 800hp, $900 can get you a flywheel/PP/disc that can get the job done. Just as quick if not quicker than an automatic, while being easier on trans/driveline parts. The key is adding a clutch hit controller, which enables you to match the hit of that clutch to the engine. You will then be able to dead hook the launch without bogging the engine, which is far more consistent than chasing track conditions for just the right amount of wheelspin. And you will be able do it with an 833.

If you want to know what a clutch hit controlled dead hook launch looks like, check out the heads-up pro-tree NMRA Coyote Stock class. Automatics and trans brakes are legal there, but you won't find any.
