Thanks everyone for contributing to my education.. It seems if you want to move up in the drag racing world, delay boxes, auto shifters and throttle stops will be required and so... I've started my learnin on these now..

I have a PPP shifter, so I will simply order their auto shifter kit.. however I do have one more question about the throttle stop..

How important is disc style throttle stop compared to the standard blade type? The disc type sounds like its more adjustable, but is also twice the price..

Thanks
