Kraftwerks sent it separately. There are two pulleys that are MUCH smaller.

The older kits came with a 100mm crank pulley and 75mm SC pulley. I saw ~11.5 psi on this one

The newer kits have a 128mm crank pulley and a 95mm SC pulley I saw ~9psi on this one. There's a high boost pulley that's 90mm and apparently a smaller one than that??

If you want the high boost pulley it's about $100 if I remember right, just call and they'll sort you out

Bought the kit used, it came with the used kit, but he said the pulleys were sent separately. He did not install the new pulleys. (Sorry I can't be of more help)

Talk to your tuber first and see what they suggest. A high boost pulley on a stock engine will most likely require E85

[rj101592]

There is a 95 mm pulley which is the standard pulley now, but the pulley has different numbers on it for some reason. The 90 mm is the high boost pulley and then there is an 85mm pulley, which is not recommended as you run the chance of over spinning the blower, so you must lower your rev limit. High boost pulley, you basically must run nothing but e85.. so it is not recommended on a daily. The high boost pulley is 100$, but if you speak with CJ I believe he will cut you a deal on it if you show proof you are indeed running their kit.

Jesus, very jealous at that. What numbers did you put down? You sure it's the 95mm pulley?

[Jusjones]

100% sure the pulley set up is correct I'm almost wondering if they shipped the wrong supercharger either way he said it was 2 much for this car lol

It's entirely possible. Unfortunately they are closed for the weekend. Hopefully it's drivable and you can have some fun this weekend

[Jusjones]

Yeah it's completely drivable he just said don't romp on it too hard throttle I'd very touchy almost like a root style charger
