The ClutchTamer gives you a way to control the pulldown rate of the engine, basically how fast the clutch pulls down engine rpm.

Here's a graph of a ClutchTamer launch with clutchless shifts, notice the difference in pulldown rate between launch with the ClutchTamer and the shifts without. There's adsolutely no wheelspeed after a 7100rpm launch, very radial friendly...



This was using a G101a, Ram diaphragm PP and Ram 900 series disc. The class doesn't allow radials (sealed engine class), so the little wheelspeed spikes after the shifts were not a problem for the slicks he was running.

If he were running radials, either more delay or a tap of the clutch pedal would have eliminated wheelspeed after the shifts as well. Not a problem for those using the clutch pedal to shift, they do it automatically.
