We took a NASCAR engine that had been sitting for 20 years and put it back on the dyno. Then we honed it, swapped the pistons and the rings and put it back on the dyno. Why? Because these are the kind of things we explore in the @EnginePerformanceExpo . In this video, we show you the results of this test and give you a taste of what's on tap on the Engine Performance Expo channel.
We’ve actually run this same test on two different engines, and the results were the same both times. With the old pistons, rings and hone, the engine made 730 HP with the baseline carb and fuel (32 degrees of timing). With the new rings, pistons and hone, the engine made 773 HP with the baseline carb and fuel at 30 degrees of timing.
