Willy’s offers a top of the line experience with our chassis dyno sessions. We have two types of dyno one of which is our Super Flow the other is a Dynojet. Our Dynojet features the latest version of WinPep software with O2 sensor technology. This is vital in detecting fuel and ignition problems as well as driving issues. Equipped with a unique starting system, our Dynojet will spin the rollers 18 MPH, which will start World of Outlaw sprint cars. Also, this helps clutch wear problems associated with super speedway cars with high gear ratios. Call to schedule an appointment, come spend the day with our staff of highly trained professionals and watch as they find hidden horsepower. Although Modifieds, Late Models, Sprint Cars, Midgets, and Mini sprints are of the common few we see, other racing styles are welcome.
