I heard somewhere that if you are using a large crank pulley to make high boost can cause damage to the front seal and harmonic dampiner because there is a lot of tension on the blower belt. Can someone provide me with info on this? Like i said, I'm not sure this is true, but I heard it somewhere.

 

anyone know? RSKrause?

 

I am running an 8.5 in (blower) crank pulley and am having no problems.
