While Supplies Last

This Mustang Supercharger, from ROUSH® can add some serious power to your 2005-2006 Mustang GT.

This Ford Mustang supercharger kit brings the total power at the flywheel to 435 hp / 400 lb-ft, adding 135 hp and 80 lb-ft over the stock Ford Mustang GT 4.6L, 3-valve V8 powertrain system.

The Mustang supercharger works with both manual and automatic transmissions and comes with all needed instructions, fasteners, hardware, and brackets. No supplemental kits are required with this system.

The heart of this Mustang Supercharger is the M90 ROUSHcharger. This line of ROUSH Mustang Supercharger kits has been thoroughly developed, used, and proven by ROUSH over thousands of production vehicles and has had several years of life out in the field. Not only is this Mustang supercharger a great value for getting a bump in performance, but it is virtually bullet-proof as well. That's why we stand behind this kit with an industry-leading 3 year / 36,000 mile drivetrain warranty or one year on ROUSH® components for vehicles already past their warranty expiration date. Please see the ROUSH warranty for more details. This supercharger is legal for use in all 50 U.S. states.

This Mustang Supercharger kit includes a roots-style ROUSH M90 supercharger, 73mm supercharger pulley (generating 5 PSI of boost), air-to-water intercooler system, intake manifold, and high-flow fuel injectors, induction system and fits 2005-2006 models. Another key element of this system is the special ROUSH calibration. Not only is this element instrumental in maximizing performance, it is also key to protecting the engine from fuel mixture problems, such as burnt pistons, over the spectrum of environmental extremes.This part now utilizes the ROUSH Flash Voucher card to be calibrated using ROUSH Diagnostic Tool (RDT) software and pass-thru device. If you do not have access to an approved pass-thru device, you can send your PCM back to ROUSH to be flashed for an additional $100.00 fee.

Roots M90 Supercharger

Rating of 5 out of 5 stars 5 / 5

By   November 9th, 2012

I had installed on my 2006 GT mustang, automatic, the roots m90 supercharger. I had no idea that the performance would be as great as this supercharger has developed. The automatic comes with 3:31 gears, i had to put 101/2 tires on the rear wheels just to get on the interstate. I know there are faster cars out there, but if it is apples to apples my mustang will run with the best of them. I am very pleased with what roush's supercharger has done for my car. Look out 5.0 !

I just installed this kit on my 2010 mustang gt and wow what a difference! I was considering trading my car in for one of the new 5.0s but there's no need to do that with this blower. The car runs great with the Roush tune and the car feels like it has a completely different engine under the hood.
