On The Dyno

Dyno pulls for the ’11-present Mustang’s manual six-speed transmission are made in Fifth gear, which is the 1.00:1 rev ratio for engine and trans.
As you see in this graph, Sinister Mustang’s ’11-’14 Mustang Performance Kit clearly delivers. Ultimately, we saw solid rear-wheel horsepower and torque gains from each upgrade piece that we installed on Victor’s ’12 ’Stang.

Regardless of engine platform, basic bolt-on performance parts are timeless upgrades for V-8-powered Mustangs. In this exercise, highlighted by loading Victor Becerra’s ’12 GT with Sinister Mustang’s new Performance Kit, we once again see how well the Coyote adapts to enhanced and improved intake/exhaust airflow from literally the simplest of do-it-yourself upgrades.

The 30 peak-horsepower gain we saw (at the feet) on GTR’s Dynojet chassis dyno really says a lot about the pieces that Sinister has grouped. At the time of our test, only the last of the late-model GT engines (Three-Valve 4.6 and Coyote 5.0) were covered in all-inclusive package form. However, we understand the company is looking to expand its lineup, and may have hop-up parts for pushrod, Two-Valve 4.6, and Four-Valve 4.6 engines by the time you’re reading this.
