Roush vs. Whipple Supercharger

Roush vs. Whipple Supercharger

Should I buy the Roush Supercharger or the Whipple Supercharger? This is a question we hear almost daily.

Before we put them to the test, we had to do a little research on the history of both companies.

Roush's history dates back to 1964. Jack Roush was a lead engineer for engines and powertrains at Ford Motor Company. Roush has now morphed into Roush Industries which is the overarching company that covers a lot of different things. One thing that people don't realize is that Roush's primary business is providing engineering services for the big three auto manufactures. In addition to that, Roush also has a leg of their company that designs and builds roller coasters for a large American amusement park! They've since taken their love of Ford vehicles and developed that into Roush Performance. A fun fact is that Roush Yates Engines makes the 3.5L EcoBoost that is in our Ford GT!

TCcustoms has recently become a Whipple dealer and we are very happy with their products and customer service. Whipple came to be when Art Whipple, a drag racer, teamed up with Sprintex to build his own supercharger. They are the only manufacturer to have a supercharger for the 2005 and 2006 Ford GT and now make the Ford Performance supercharger!

We took both of our supercharged trucks to the dyno to compare the horsepower and here's what we learned:

Whipple:

6th gear pull: Max Power = 517.02 at Engine RPM = 6.76, Max Torque = 458.09 at Engine RPM = 4.16

5th gear pull: Max Power = 521.20 at Engine RPM = 7.14, Max Torque = 4547.96 at Engine RPM = 4.15

4th gear pull: Max Power = 519.96 at Engine RPM = 7.11, Max Torque = 451.17 at Engine RPM = 3.35

Roush:

6th gear pull: FAIL

5th gear pull: Max Power = 519.84 at Engine RPM = 7.11, Max Torque = 451.15 at Engine RPM = 3.35

4th gear pull: Max Power = 488.14 at Engine RPM = 6.89, Max Torque = 411.94 at Engine RPM = 5.36

Keep in mind that we were doing these tests in humid, 84 degree weather so were not looking to make numbers, just compare the horsepower of each.

The difference between the two was about 31hp and the Roush was closer to its stated horsepower than the Whipple.

Another thing to consider is the pricing of each.

A Whipple will cost you $9,195 without a warranty. The additional warranty will cost $650 totaling $9845.

A Roush will cost you $8,749 with the warranty included.

So the question is...Is 31hp worth $1100? That's up to you!
