Wahoo, just got my new blower drive pulley extentions from the machine shop. Paxton accidentally sent me pulleys for the Mustang blower and refunded my money. I got to keep the pulleys and had extentions made for them.
The Dodge 4.7L supercharger pulleys extend out about 3/8 of an inch further than the Mustang pulleys. When I put the 3.25" pulley on, it sits way to close to the blower. I had to fabricate a spacer while these were made in the machine shop. They push the blower pulleys out far enough to line up with the motors serpentine belt.
Thanks man. The best thing is they ended up being free. Even the machine shop didn't charge me anything to make them. They had exactly the right size scrap material and did it for free. I agreed to give the machinist a ride in my truck, lol.
