wat??

Because the cams spin at half the speed of the engine, so 1000rpm higher cut off = 500rpm more for the cams

wtf??

i think he means if the rev limit is raised by 1000rpm the cams will be spinning 500rpm faster then previous rev limit.

I thought camshafts rotate at half speed of crank? if at same speed then e.g. int valves would open everytime piston goes tdc?

Mocchi is correct.
