How would you wire a 2 step into a car youre footbraking a who sells a transbrake for it? Been thinking about this for a while,I dont like watching the tach during bracket racing. Prblem with bad reaction times when I do.

only one i know that made one was Harlan, and he does not make them anymore, have to keep an CLOSE eye one the for sale section. ther trans brake would help but, you still only have RPM's not the instant power of a two step, the two step will alow you to be at full throttle, with the only limmiting factor being the spark witch as we all know is faster than any mechanical part. so when you hit it at say 1200 rpms at full throttle vs. just using the gas pedal to raise the rom's up with out spinning., its a major difference.

It could cause more tire slippage or spinning if you were on non track worthy rubber and dont have suspension. Most guys on here serious enough to even consider running a 2-step are serious enough to already have a decent suspension/tire combo going.
Harlan made a 2-step, synergy makes one as well for you LSx guys. For us LT1/4 guys we can just call summit and order an MSD piece for like $75

Yes the two step has major difference in paower. lets look at them two by them selves.
regular... holding brake and using gas pedal to rasie RPM's to 1200. your throttle body is probably open 10%, you injectors are only giving the engine X amount of fuel becasue it is readind the throttle position sensor, and the air intake. so then when you let off gas and floor it, the engine has to build up... throttle body open up, engine suck in air, injectors start pumping WOT fuel leves.
Two step... hyolding brake Floor the gas pedal and two step hold rpm's at 1200. the throttle body is wide opem, and the injectors are giving the motor WOT fule levels (this is why you cant use them with catalitic converters) the ONLY limiting factor the the spark, and once you let off the brake its instant, you motor does not havt to keep up. its allready there.
MAKE A HUGE differnece.
take for ex. dumping my car at 2000. in second gear, becasue first is two easy for test perpuses. the car will spinn bog down a little then the motor will build and spinn thew the whole gear.
set 2 step at 2000 and dumpo it in second and the car will act like you dumped it in wet mud in a granny low, just blows the tire off the car. the tack will go to red line like there is not driver tain.
