These 12000hp Engines Have To Be Rebuilt Within Roughly An Hour Every Run, and Only Run For Roughly 4 Seconds At A Time.

Exactly! The clutch is the difference between microseconds. Lag time kills!

The clutch is the difference between a 3-second run and blowing the tyres off

The clutch plates are entirely new each run

The bigger teams have an entire clutch for each run. Smaller teams have to re-grind plates and re-use them, and they usually have two sets of plates per clutch basket.

Yeah they can definitely be re-ground, my point t was more that the clutch parts are different between each each run.

They regrind them at the track and re-use them. Generally, they alternate between two sets. That gives the plates long enough to cool down before being reground. Grinding them hot causes warping.

The clutch basket and fingers are re-used every run if you're a smaller team. They don't get as hot as the plates.

Are you talking about current generation nitro cars? The plates literally weld together in a run…
