Crank pulleys
 

Havent seen anyone with one of these on their car yet. Worth it or not? I know they wont free up a huge amount of horsepower but every little bit helps right? :truestory:

I don't know what pulley your engine has. If it has a dual-mass (read: with rubber in the middle) pulley, don't go for a solid pulley unless it's a gen-u-wine race car with the attendant budget for engine work as needed.

i was thinking if fluidampr makes a crank damper but i guess it's for reducing NVH..



sometimes the oem harmonic balancer is best..if you want to free up power from the crank, invest in a lighter flywheel..especially a lightened and balanced flywheel,
