IT ALL COMES DOWN TO RESULTS
We make sure we hit our target horsepower and proper torque with every crate engine. We use an advanced computerized balancer to get our rotating assemblies within two grams, ensuring silky smooth power over the entire RPM range. That's precisely why our engines sound and run better than our competitors.
BRAGGING RIGHTS INCLUDED!
A Comprehensive, dyno-generated printout showing these critical specs will accompany your delivered engine. No more guessing or wondering what your installed engine's real-world peak horsepower and torque ratings actually are. Any doubters in the crowd? Simply flash 'em your dyno results!
