Chapter 10- The Importance of a Clutch Pedal Stop

If you want consistent results at the track, it's important to release your clutch pedal from the same point every launch!!!

Before you test your ClutchTamer or Hitmaster, it's very important that you install a clutch pedal stop and verify it's proper adjustment. By proper adjustment, we mean a setting that allows enough clutch dis-engagement to achieve clean hi-rpm shifts, also enough dis-engagement to be able to put the transmission into gear without grinding when the clutch is warm. Using a pedal stop helps ensure a consistent release point, which in turn helps ensure that you get repeatable results. If for some reason you have to change your pedal stop height after you begin the setup process (maybe you find the clutch isn't releasing cleanly which causes a shifting problem), you will need to go back to Step 1 and do the setup process all over again.

The best pedal stops are located up in the pedal box itself, much better than a flexible floor or firewall. If your pedal box originally came with a rubber pad to limit pedal travel, we recommend removing the rubber and replacing it with a solid aluminum block. Typical rubber bump pads usually just push into a slot, just drill thru the slot so you can bolt in a chunk of aluminum. A bolt-in block makes it easy to shim the block with washers if needed

Don't "pre-load" the clutch before launch! Letting the clutch drag before launch can increase clutch temp quite a bit, which will then affect how hard the clutch hits. It also puts one at risk of red-lighting if your opponent burns your clutch down by late staging. That was one of the big downfalls of the Magnus, as you had to pre-load the Magnus to minimize reaction time. With a turbo, sometimes it takes a while to get the car staged. There is no need to pre-load with the Hitmaster, as there is no fluid restriction to slow reaction time. Not sure why he still does it. Guys that want to go rounds with a clutch also pay close attention to clutch temps, especially with iron friction material.
