[Fot] TR4 crank

[tr4racing at googlemail.com]

Hi,

I run a stock crank too. I use revs up to 6400 (rev limiter) but in most cases I shift around 6200.
I got benefit of a light aluminium pulley on front and a 6 kg light flywheel / clutch unit. I found very tiny cracks at main 2 and 4 but we managed to grind them away. The crank is in my current race engine.

I would say a stock crank is a good unit when to keep eyes on cracks and stay below 6800.

Cheers Chris
