ASP pulleys with superchargers

I don't have the pro-charger but I do have a supercharger and am in the same boat. I would like to used the ASP underdrive pulley but would need to put a smaller pulley on the charger. Once I get the LS1 edit it will be easier to try it. Anyone done the pulley with a mangacharger?

I also want to know this. Does the ATI or MMS crank pulley hook up properly to the ASP underdrive crank pulley? Somebody has to know.

I have always wondered this too. The way I see it, you would have to "overdrive" the SC to get the imput shaft speed back up to where it should be (ex: 9 lb pulley would give you 6 lbs boost). Dont some SC companies have a new crank pulley in their kit. I though the Votech did this (or am I wrong?)

I dont think the ATI supercharger kits would be slowed down by a different crank pulley since the supercharger crank pulley mounts on the existing crank pulley. It would still be spinning at the same rate. Only the accessories would be slowed.

I had an ASP underdrive pulley installed B4 my Blower. I had to remove but thats because I went with an 8 rib drive system.
But b4 I had gone with the 8 rib I did research to see if I could keep the ASP. I was told that I could keep it but I would have to go with a smaller blower pulley to see the same amount of boost. I was also told that I would have a greater chance of belt slippage because the belt will have less surface area to grab onto the pulley.
My advice, If you go with a blower just upgrade your belt system to an 8 rib and be done with any future belt slippage problems. You dont want the headaches. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

If you run a smaller than stock crank damper you'll see less boost with the ATI Blower pulley. If you compensate with a smaller ATI Blower pulley, you'll get the boost back, but you'll have less belt contact on the smaller blower pulley and may have belt slippage problems.
Not worth the headache. Sell or don't buy the ASP. Also, you want a superior damper for a SC, not something worse than stock chewing up your bearings with the rotating assembly not dampened properly.

An ATI F-body supercharger system will not be affected by crank pulley size since the crank pulley that turns that charger remains the same size. The question is will the supercharger crank pulley mate together with the ATI underdrive crank pulley? I would prefer to use a fludamper but who knows if that would work either.
