About Us

  • Dennis Knowles has been building, testing and producing the best durable race engines since 1975 and over the years has earned a proven track record of high quality performance built on knowledge, experience and expertise. Tell us what you need and we will make it happen. We know that hardcore, die-hard racers take pride in their cars, but most importantly their engines. No one wants to have the same engine power as their competitors. At Knowles Performance Engines, we can build you a completely customized engine, based on your specific needs. Every aspect of your engine is professionally balanced and assembled for power and speed. We record every detail of your engine from part numbers to oil clearance and we do all of our machining in-house to make sure that the work is done right every time. Knowles Performance Engines specializes in dirt circle track engine building. While some people may not many may not realize that there is a lot of technology and discipline involved in building and tuning circle track engines, with our experience, we know what you need to be on top of your game. Whether you’re looking for a new build from the ground up or a freshening your engine as an essential part of preserving your racecar, trust Knowles Performance Engines for a complete and extensive full engine check and rebuild. We're available Monday - Friday, 8:00 am to 8:00 pm. Our phone is open for technical support during race hours or you'll find a Knowles Performance Engines Rep at the race track.
