Front Drive Reconfiguring
 
Here is what we are working on right now to achieve the most performance from your Eaton and TVS superchargers.
*** Eaton & TVS GT-500 Front-Drives.

Stiegemeier's is widely recognized for the 500-RWHP SVT Cobra obtained with a simple recipe of:

  • Ported and Polished blower combo
  • Cold Air Intake
  • NGK Plugs
  • 2.76" Pulley
  • Single Idler
  • Belt
  • Custom Tune

Stiegemeier's proudly offers the 600-RWHP 600-RWTQ Stage 5 Shelby GT-500 "MSBK" kit which consists of the above, PLUS the reconfigured front-drive options which includes the 3 pulleys, custom machining, and new seals and bearings. The pulleys are easily interchangeable for up to 18# Boost!

The "MSBK" kit is also available for the GT-500 TVS supercharger units (shown below).

Please Note: This kit requires the adjustable idler pulley bracket above.
 

600+ RWHP and RWTQ?   YOU BET!! Read on...

Our hottest new development is a new configuration and set up for TVS and GT-500 front-drives. Here are the details:

On arrival the 2007 Shelby M/122 Eaton supercharger was fitted with a 3" pulley which delivered 10# boost. The first pulley we installed was a 2.6" which delivered a respectable 14# boost. We then went with a 2.5" pulley which yielded a slightly higher 15# boost.

Not satisfied, we wanted enough boost to crack 600-RWHP and 600-RWTQ with a ported blower combination (Cold Air Intake, stock exhaust, new NGK plugs, and a custom tune). We wanted this thing to scream!

The Stiegemeier team took a Stiegemeier ported blower, reconfigured the OEM front drive to accept a 2.2 pulley which in the end delivered 18# boost and an incredible 605-RWHP and 621-RWTQ !!!

All of this testing evolved into an interchangeable kit that comes with 3 pulleys: a 2.6" which delivers 14# boost, a 2.4" delivering 16# boost, and a 2.2" giving you an outstanding 18# boost. This allows you to choose how you run and make changes quickly and easily. The same belt tensioner pulley is used with all 3 drive pulleys simply by switching to optional mounting holes on the tensioner bracket. We call it the "Multi-Stage Boost Kit" (MSBK).






Option 1: We highly recommend Blower Case Blueprinting and Radiusing. Add $300.00
Option 2: Blueprinting & Radiusing, TB&PL, plus Blower Case MAX Porting. Add $600.00
