what pulleys are people using for their race cars?

is the standard A+ vibration damper pulley any good for high rpm?

what size pulleys do you use?

 

I use the large standard waterpump pulley, the standard A+ vibration damper bottom pulley and a 2.75" alternator pulley.

depends on how much money you have and what you want the pulley/damper to do.

don't have an alternator.

use the water pump pulley that gives the right required length for the belt. but soon there will be no water pump.

what do you call high RPM?

 

and I would be moving away from the cast standard dampers.

 

oh and there is no "standard" A+ damper I know of three (at least) different mass versions.

more than 7k upwards is what I call high rpm

 

why would you be moving away from cast dampers, weight?

 

this is what I call a standard A+ crank pulley/damper:
