NuJet impellers are precision investment-cast using aerospace-grade stainless steel. Each impeller is then heat treated, passivated, CNC machined to exact tolerances, and dynamically balanced. As a result, every Nujet impeller is designed and manufactured to be more precise, more consistent, and more technologically advanced than any other impeller on the market today. NuJet claims you can expect about 2 mph gain on top end with solid holeshot on all Nujet impellers.
There are three levels of impellers shown on the NuJet application chart located on every impeller info page...
- Stock: Being little or no modifications made to the motor.
- Limited: Modifications usually limited to bolt on items, slightly increasing horsepower.
- Modified: Limited bolt on items in addition to modifications including internal changes with considerable horsepower increases.
