We recently completed a Cummins 12V Sled Pulling engine for a customer. Can’t wait to hear it run. We are looking into the possibility of getting our own Engine Dyno! We could really use one and our customers would love it. Over the past several years, more and more diesel enthusiasts are becoming passionate about diesel truck sled pulling. Diesel motors sports is an expensive hobby. It takes time, dedication, knowledge, and good ole fashion hard work.
