There has been great response to the MP 25% OD pulley combination that we used on the MPX blower test car but the pulley arrangement on that car is custom with a one-of-a-kind blower pulley, ESM JS pulley, and MP crank pulley. I have talked Charles into drafting up the design for a MP version of this custom setup. The only thing is we have to let him know that we really want this setup by placing orders before he can have production started.

Hadn't occurred to me initially but for those with an MPI, S-Port, or other ported blower, the 10% JS and 5% 10 Rib blower pulley combo would be an excellent combination with a stock or UD crank pulley. A great way to eliminate belt slip on that combination too.

Details on the pulley setup:
All pulleys will be made from 6061, sand blasted for adhesion, and then hard annodized for long life.
The crank pully will be the same as is currently offered from MP with stock acc. drive ratio and an 8 rib JS pulley drive. The JS pulley will also emply a 10% OD and will have an 8 rib driven side and 10 rib drive side to the blower. The blower pulley will be a 10 rib press-on 5% drive size.
The group buy will allow you the option to buy either all 3 pulleys or just the two uppers if you already have the crank pulley.
Included with the purchase is also both MP high tension springs for the tensioners and Gates belt (or belts depending on which package you get) which are known for having the best grip and longest life for this kind of application. This is a group purchase benefit only!

Minimum 15 orders needed to begin production.
If you have an MPIII or plan on getting the MPX you NEED to get in on this now!
