  • Oil Cooled AC-34

Our new Stainless Steel Oil Cooled AC-34 Motor is a new addition to the HPEVS AC-3X family of motors. The attached graphs are the updated dyno numbers that we have attained in house. The peak horsepower has not changed. We have added the graphs containing the continuous data (3-6-15).

Your continuous horsepower ratings will vary based on the design and efficiency of the oil cooling system.
