Meet the Owner
Hey! I’m Don Guhl, the owner and founder of Guhl Motors. I have always been interested in racing and improving performance on the track, and have been doing this kind of stuff since the early 1980’s. I hold a B.S. in electronics engineering from DeVry University. My proudest achievement in the racing world was when, in 2001, I developed the world’s first methanol fuel injection conversion system for a 600cc micro sprint. Outside of work, I have a wife and two kids who I love spending time with. I am very passionate about what I do, and I hope you’ll consider doing business with us!
