Bolt-On Dyno Test - The Main Event
Battle for Bolt-On Supremacy
Making the Grade
As we explained, publishing dyno results has long been our bread-and-butter method of validating high-performance parts for late-model Mustangs. For this exercise, we decided to go a step farther with our data, quantifying total power and torque gains by their overall percentages.
In a nutshell, percentage change is all about comparing old to new values. To calculate percentage (performance) increase for the bolt-on groups we tested, we used a basic math formula, plugging in each package's baseline and final power/torque numbers.
Step 1: Subtract baseline power/torque value from final power/torque value
Step 2: Divide the result by the baseline power/torque value (it will be a decimal number)
Step 3: Convert that number into a percentage--multiply it by 100 and then add a "%" sign
As you see in the chart, top performance was split across two platforms when examined in this fashion. The Coyote proved to respond best from a horsepower standpoint. Surprisingly, the Two-Valve engine rocked all players by a ton in the torque department.
Despite the New Edge surprise, the data plays out the way we thought it would overall; we believe the results would be similar had components from other manufacturers been used.
Now when you're shopping for your next project 'Stang, you know how it will respond to its first round of mods.
|Mustang||Power Increase||Torque Increase|
|New Edge 2V 4.6||9.05%||8.32%|
|S197 3V 4.6||7.49%||4.21%|
