2 step and Procharger?? Just wondering who on here is using one at the track and how much it helps. Will it build boost to whatever you have it set at correct (engine rpm)? Just like a turbo? Car is a 6 speed too.

no, it wont help build boost at all. a supercharger is driven by the engines belt, the only way to build more boost is with more rpm's.
it'll help you be alot more consistant though, launching will be alot easier.

Prochargers need engine load to build boost, not just rpm. I'm guessing that since your a 6 speed car it will not build boost because you will have the clutch in and the motor won't be against a load, no matter what the throttle position is at. Procharger and 2 step on an auto trans will build boost given enough rpm because the motor will be fighting the tq converter.

Yea it would but that has nothing to do with a 2-step. Which is what the original poster was wondering. If he is looking for consistancy then yes the 2-step will help. But, regarding boost, whats the difference in droping the clutch with or with out a 2-step given the same rpm? I say nothing, as your going full throttle immediately anyway.

Superchargers dont need load to make boost, thats a turbocharger. The bypass has to be closed though, with a M6 car at WOT the bypass should be closed if its adjusted properly.
At 2800rpm on the 2 step with the D1SC I see 2-3psi, with the F1A I used to see around 5psi at 3000.
With a manual trans drag car its a bitch to hold it at a certain RPM pre-launch. 2 step is a must have if you drag race a lot, I run the same off the foot brake and 2 step so having that little bit of boost doesnt make much difference in ET really. But its a lot more consistent when you just have to hold the pedal to the floor at the line and not look at the tach.

Another good thing about a 2-step on a manual car connected to the clutch is it makes powershifting easier/safer. You can hold your foot on the throttle, press in the clutch, and shift without worrying about over revving the engine. The 2-step will stop your rpms from constantly redlining while the clutch is down. It also takes torque load off of the drive train allowing the shifting to go in easier.

Cool, I see you did get a new Shelby Mustang! Bob
