| It is my pleasure to right a letter of endorsement for Hagedorn Racing Engines. My family and I have been involved in the Truck and Tractor Pulling circuit since the late 1970’s. I got acquainted with Terry and Sheila Hagedorn through local events and competitions. I found Terry to be a man of great knowledge as well as a fierce competitor. Hagedorn’s were always the competitor to beat. I started doing business with Hagedorn Racing Engines in 2008 when Terry built the engine for my Hot Shot Pulling Truck. I found Terry to be an amazing workman with great craftsmanship. The products and services you get with Hagedorn is surpassed by none other. You get a one-on-one personal service. It’s pretty rare to actually get to talk to and communicate with the man building your motor, which is exactly the case with Terry Hagedorn. Hagedorn Racing Engines will customize your engine for your personal needs and the needs of your truck. Nothing is “assembly-line” work with Terry. Hagedorn tries to match your motor with your truck, the driver and what works best for each. Every engine built is one-of-a-kind custom made, and built to customer specifications. You will find no exact replica of it anywhere. Terry Hagedorn also makes himself available for questions. He always welcomes my phone calls with questions, information seeking or simply asking for advice. The Hagedorn engine in my Hot Shot pulling truck took points championship with Outlaws in 2009 and again with the X-Caliber Association in 2013. |
We have been pulling since 1998 and met Terry in 1999 when we had questions due to being new pullers. We needed to know how to set our fuel so we pulled a plug out after our run. One of our competitors said to take it to Terry Hagedorn he will help. When we took the plug to Terry he read it and told us how to adjust our fuel. We have been going to Terry for the last 15 years. He has helped us set up our fuel at the track, set our truck up, build our frame, refresh our motor each year and build our motor bigger and better.
He has also, helped set up our clutch, rear end, front end, tire pressure, and assist us in choosing just the right gear to run on the different tracks. There has been many phone calls over the years late at night with, “What do we need to do?” Terry replies “Well,” and fixes the issue at hand over the phone. Terry has lead us to championships over the years. He keeps his phone close after every pull and is excited to hear how we finished. We have been very pleased with the vast knowledge of our motor builder and would highly recommend Terry in any motorsports arena.
