How stages work

Three decisions.
One dyno sheet.

Pick the platform

Every Ford Mustang platform from the 2011 Coyote to the 2020+ GT500 has its own published menu, because a Stage 3 on a GT350 is a different parts list from a Stage 3 on an S550 GT.

Pick the power adder

Naturally aspirated stages stack bolt-ons, cams and heads. Procharger stages add a centrifugal blower. Twin-turbo stages use Hellion Sleeper kits or our in-house fabricated kits — and past Stage 3, built short blocks and transmissions come with them.

We install, we tune, we dyno

Baseline pull, install, Shoemaker Performance or Bumbera’s calibration, final pull. You get the before-and-after sheet, a Bumbera’s plate frame and a Bad Fast decal with every package.

Home of the record

World’s fastest N/A Gen-3 S550.

Built and driven by Bumbera’s. The parts that did it — the OTR intake, the RPG shortblock, the Frankenstein heads — are on the Stage 4 and 5 N/A sheets for the 2018–2023 GT.
