Gen 3 2.9L Whipple S550 Dyno Results - Video -

Hello everyone,

We at Fathouse Fabrications recently finished up installing a Gen 3 2.9L Whipple Supercharger kit on our customer's 2016 Automatic S550 Mustang GT. The only other modifications to the car are Roush Axle-Back Exhuast and billet OPG's. We tuned the car conseratively on 91 octane because it was getting shipped overseas, and on 9 psi the final results were 673 rwhp and 559 rwtq.

Below is the dyno video as well as some photos of the install.

Thank you! we were pleased with the power as well for being on 91 octane.

Nice to see a base kit throw down.

Howdy boys! Thanks for compiling that video, it's awesome! And yeah it's my car

Am super happy with the car, now I just need it to dry up a bit so I can get on it a bit without fear of dying ha!

Congrats man! that's pretty damn good power for 9lbs. on 91 octane. You are the first Guard Metallic California Special I've heard about besides mine.

Stupid question, I know. What sort of highway mileage would one expect?

Less :cheers:

It really depends on driving style but if you drive it conservatively they still get mid 20's with a supercharger kit.
