Yeah I know......so what we do is remove the slipper for a more direct drive system so we can come off the line with some punch. However the Rally's drivetrain isn't really designed for on-road applications, although its been said that you can. So what you did was lower the car, removed or tightened the slipper all the way so that it didn't slip during the inital punch, then ran the car. I would have done it if I was running a rally onroad, so call me a noob.
Are you running a two belt system?
