Please forgive the newbness... but I am used to the GM 3.8 Series II S/C motor - been running a modified Grand Prix since late 2002.

I'm a little confused about how the multiple pulley swap works... but not having a Crossfire, I've obviously never been able to dig into the engine, just look at one at a dealership with the engine cover on

With the GP's, the S/C has its own belt shared with just the crank pulley, while the accessories have their own belt on the crank pulley.

We just swap the pulley on the S/C itself to raise boost, but if I am getting this correct, you guys are swapping the crank pulley for more boost?

The reason I ask is, our pulley swaps cost us about $150 nowadays (closer to $300 back in 2003), and yours are costing nearly 6 or 7 times that much, because there are other pulleys you swap. Is there a reason that the supercharger pulley itself isn't swapped? The same system that is used on the GM motor should work for the SRT6 motor, just a question of finding the right pulley sizes. Just wondering why you don't do it this way... does it have to do with the electronic clutch engagement?

I couldn't find much relating to this via search, but if it's a common question feel free to private message instead of bringing it back to the top.

Just trying to get a technical grasp on the SRT6 mill.
