What size is our crank pulley??!!!!???!
what is the size of the crank pulley? i need to know asap so i can figure out what size blower pulley i can go with for my vortech V2 SQ S-trim... i have a 3.12 on there right now that makes 14psi at 6500rpms.. i want 17-20 psi around 7200rpms without overspooling the blower... what would be something i should look at?

its ok man... i just read on kenne bell's web site it says the stock pulley is 6.5 inches... so that means if i put a 2.87 pulley (which i thought i wanted)... at 7200rpms (shift point), i will be spinning the blower 64000 rpms... that is 14000 rpms above what they say it can go!! dang. lol. keeping the same pulley i have, they say it will rev 53000 rpms... which is 3000 over... i talked to a vortech rep earlier and he said that it is ok to go up to 5000rpms over what they reccommend... looks like i cant get a smaller pulley for revving that high.. wonder what my power output will be now though?
