Im putting a Vortech sc trim on my 92 and I have BBK underdrive pulleys on it, do I need to put the stock pulleys back on? I thought the kit comes with a seperate crank pulley that bolts on to the exhisting crank pulley and runs the blower off of that, so how would that effect the blower if it basicly comes with a new crank pulley (or is it a crank pulley?)..Im confused....what does the seperate pulley that comes in the kit go too?? please help

yeah, I believe it is a two piece pulley set up that bolts to your stock crank pulley with a spacer, so yes you will need the stock crank pulley.
If you don't have yours, go to a junk yard, 10 bucks.

There you go, my bad.
I thought it was just like the Powerdyne setup.

so I can use my underdrives?? I heard using underdrives would give you less boost...how is this possible if the blower belt runs off of another pulley that is just bolted to the existing pulley??

the old N1ks ran off the stock crank pulley. the new ones and all the vortechs use a dual crank pulley system, so it is not an issue
