Roush M90 Brenspeed 490R ROUSH M-90 Supercharger Upgrade Package 

The Brenspeed Calibrated ROUSH M-90 Upgrade Package can upgrade your stock 435 HP ROUSH M-90 Supercharger to 490 FWHP.  Using a 2.49 Supercharger Pulley, Cold Air Intake, and Brenspeed Custom Claibration you can see an extra 40+ HP to the rear wheels.  Plus you can keep your stock Roush belt because of the supplied larger idler pulley.

Please select your pulley type from the drop down menu above.  If you dont know what type you have thats OK.  Brenspeed will contact you after your order is place for your tuning information and we will help determine what style you have at that time.


- Brenspeed Highly Recomends that you upgrade your spark plugs to a One Step Colder Plug because of the increased boost.  Please choose your Spark Plug Style from the drop down menu above.

- You must use a Fuel System Upgrade with when installing this Brenspeed Package if your Mustang has other modifications such as headers, cams, etc  because of the extra demand placed on the stock fuel pump.

Ordered the cold air and tuner combo. Best tune I have had. Really woke up my 5.0
