Two step and a stock crank?

I'm on the 2-step for less than 1.5 seconds on the launch, don't like washing the cylinders with a 3-step in the burnout, plus, my car won't hook dead on the converter, or I'd not be using the 2-step.

Well, good points. I am with you on the 2 step on the leave. I hate to see someone stage & got W/O on the 2 step, esp when their opponent hasn't lit both bulbs. As far as the 3 step on the Burnout I have always used it as a safety. I use it as a catch point, not the RPM of the burnout. I use the throttle to control tire speed & if I happen to hit the chip it is usually just for a split second at the end of the burnout. I'm a firm believer that engines need to be kept below an RPM that causes vlave train damage. This is especially true in FREE Spin RPM's. I also like to keep the RPM of the burnout at or just below the stall of the converter to build a little heat. I'm not sure about the Washing cylinders you mentioned, but long periods of time "ON" the chip will cool cylinders. I have studied those effects with several engines on the dyno. As far as Dead Hooking these little engines I run, That's not an option when you want the best E.T. I have always tried make the converter have max torque multiplication. You can kill that leaving at max stall. That's why I feel a 2 step is best used to control consistant leave RPM's.

I am so with you on the free rev RPM thing, destroys more engines than anything right there!
Using it as a limiter is great, but I see so many people in the bracket world that just put it on the chip for the entire burnout.....
I just view the two-step as a necessary evil......for sure wouldn't run anything other than the MSD soft touch setup.
