MoSaleen Idler Pulley Systems

Several years ago, I began experiencing problems with the belt slipping on my 2000 S/C Saleen Series I. 
At the time I had Chicane's 66mm pulley and his 110 inch belt, which was very tight. Despite this, while on the dyno, I noticed that the belt was slipping back and forth so bad it was hitting the radiator hose and a bolt that was holding the bracket on. 

In response, I created the MoSaleen™ Idler Pulley System. 

Following installation, the car saw a difference of 34 rwHP and 42 rwTQ on the dyno. This occurred at the same air to fuel ratio of 11.9 to 1. I began offering the pulley system to other Saleen owners and the results continue to impress everyone who installs it.

System for 99-04 Saleens

Compatible with Series I, II, IV and V Superchargers

This MoSaleen™ Idler Pulley System is made of metal using grade 8 bolts and a high performance sealed bearing idler pulley. Several different finishes are available for the bracket and spacers, including powder coating in most colors or ceramic coated (tumbled to look like polished aluminum).

System parts include:
1 black double bearing pulley
1 powder or ceramic coated bracket
4 metal powder or ceramic coated spacers
Combination of 4 8mm or 10mm bolts
4 washers

This pulley system is safe to use on a stock Saleen S/C, with a stock supercharger pulley and no modifications. It is HIGHLY recommended that you check your air to fuel ratio after installation to be safe. This is a MUST if you are using a smaller S/C pulley for added boost, or if you have other modifications. We do not recommend running more than a 12.0 to 1 air to fuel ratio on a supercharged Saleen. You should have a tuner device (like a X-Calibrator II) with tunes made for your car.

System for 05-10 Saleens

Compatible with Roush, Steeda, S-331 Trucks('06-'08), Harley-Davidson Trucks('06-'08) and Edelbrock S/C Mustangs

This MoSaleen™ Idler Pulley System is made of metal using grade 8 bolts and a sealed double bearing idler pulley. The system comes with a black plate. The CNC pulleys are available in aluminum or anodize black finishes.

System parts include:
2 CNC aluminum anodized pulleys

1 8mm bolt with 1 washer and 1 lock washer
1 bracket
1 spacer
1 10mm bolt

The sealed bearing in this kit is rated at 360 degrees and 12,000 rmp's. I use the system and to date my Saleen has 9000 miles on it with no issues.

You will need to provide a smaller belt for this system. Purchase one that is 1" to 1.25" smaller
than the one you are using with your stock pulley system.

This system is designed for aftermarket S/C pulleys, System 1, 2.75 to 3.20 - System 2, 3.40 to 3.60. You MUST retune following installation. We recommend having a dyno completed at JDM Engineering or Performance Auto Sport. They have tested this system and can set up your tuner device (like a X-Calibrator II) with the correct tunes for your car.
