"If we can measure it, we can improve it."

Data is the lifeblood of a Slakker rebuild.  From the biggest dyno pulls to the smallest deviations from bearing clearance specifications, we seek to quantify every single aspect of our engines. Our data obsession, along with our narrow focus, allow us to rebuild engines with the excellence that a Porsche deserves.  

Nowhere is this difference more evident than in our engine dyno room, where we test, tune, and break in every single engine that we build. While shops usually measure torque at the wheels, our engine dyno allows us to measure an engine's power output directly at the flywheel. This dyno method produces numbers that let us accurately measure — not estimate — our true torque gains.
