Is the 6" crank pulley (vortech) good or will there be belt slip with it...looking for some feed back..

Most of the crank pullies are big enough where they wont slip.. its the blower pullies you should really be worrying about.. they have to go through such a tight turn and they start slipping..

Never had a slippage issue with my 6" Vortech pulley. I'm presently running the 7" pulley with the stock 3.3" blower pulley, no slippage issues. You will have an intake temperature issue if you choose to pulley up; I added the Vortech aftercooler.

Hmm, yeah i just looked at the site and it has the 6" and the 6.66". i thought they had 7" too.

what are the boost levels with the 6"crank pulley and the 3.33" SC pulley?

ive had some problems with my boost causing problems with my MAF and now probably my MAP not reading right.

im wondering if im running more boost than i think. i dont have a gauge. and i thought my kit was the 6psi kit and no one else running 6psi or less has had any problems with their maf or anything.....

have you changed to a 2 bar map sensor running as much boost as you are?

No.. actually im on the stock map sensor.. I have been looking into a 3 bar one. What problems with your MAF??
