We live in a pretty awesome day and age when a leader in the industry like Roush Performance is offering enthusiasts more power out of their Phase 1 supercharger kits. The early version of the kit for 2015 Mustangs was good for 627 horsepower, but Roush has upped the ante with an upgraded calibration – making your current supercharger capable of 670 horsepower.

Thanks to Brenspeed‘s video dyno testing its road race car, a Roush supercharged ’15 Mustang, we’re able to bring some additional details on what’s new with the calibration.

Roush recently announced that the company will be offering enthusiasts the opportunity to upgrade their current Phase 1 supercharger kit with an additional 43 horsepower. They’ve also greatly expedited the process for upgrading  by allowing everything necessary to get started available online. To get started, all you’ll need to do is visit this link and fill out a short form on the website.

Interestingly enough, the form includes a few questions centering around your interest in a 750 horsepower supercharger kit option – we know what will be on our list for the holiday season! If you’re looking to expedite the process even faster, hit up Brenspeed with a phone call about upgrading your current Roush Phase 1 supercharger kit. They can take care of everything in a flash – literally.

If you’re looking for more horsepower, without having to change parts on your current supercharger, you really can’t beat this upgrade.

For more information regarding the calibration upgrade and what it entails, head over to Brenspeed’s website or Roush Performance to get all of the details. Also all Roush Phase 1 kits will now ship with this calibration, so every kit Brenspeed is shipping to its customers or installing at one of its two facilities is the 670 hp package.
