Description

Since the Hellcat first hit the market, it's been debated as to how much safer a clutched pulley just like the OEM decoupling 3.35" would be on modified IHI Hellcat superchargers. Litens comes through with their high quality heavy duty 3.17 pulley upgrade. Using the OEM design developed specifically by Litens this pulley will reduce stress and associated wear on your supercharger's bearings and rotors.

Kit Includes:
1 - 3.17" Litens Supercharger Pulley
1 - End Cap (dust/tamper shield)
1 - 17mm Install Tool
1 - HD Belt (10PK1470)

Litens testing shows that this pulley makes approximately 45 HP on 93 and 65 HP on MS109 Race Gas for Demon/Redeye Superchargers at sea level. Litens testing shows no tuning is required with this pulley upgrade.

Note 1: Pinning of the crankshaft pulley is not believed to be required with use of this pulley but no liability is assumed or implied by High Horse Performance, Inc. due to any damage that may occur due to unpinned cranks.
Note 2: Litens highly recommends against the use of additional idlers or heavy duty tensionsers and HD Belts with their pulley due to the higher risk of internal failure.

Please see this manufacturer Tech Bulletin to help ensure you get the best results from your Hellraiser pulley purchase.

To make things easier you may also purchase the (Pin Holding Tool) to secure the pins on the back of the snout.

Product Guidance 

Pulley RPM Chart

A great many owners of Hellcat-powered vehicles from Dodge and Jeep have learned that swapping to a smaller pulley adds gobs of power (with the necessary supporting modifications). The problem with the pulley swap options on the market over the past few years is that they lack the internal decoupling and isolating assembly found in the stock Hellcat supercharger pulley, but that has just changed.

Litens High Performance – a division of the same Canadian firm that produces the stock supercharger pulley for the Hellcat Challenger, the Hellcat Charger, the Trackhawk, the Hellcat Redeye and the Demon – recently introduced the first decoupling pulley for the IHI superchargers on the modern Mopar monsters and it has a fitting name.

 

Development Details 

For those wondering, the HellRaiser pulley from Litens High Performance was developed with some very well-known members of the Mopar Performance community. Rob Laing of Litens (High Performance design team, and a drag racer himself) and John Lussier of Tendeco presented Hellcat and Demon owner Paul Georges with the idea.
