Fuel Injection Conversion


Why Guhl?

Don Guhl (#33) wins with the first ever methanol fuel injection conversion

In the early 2000s, Don Guhl started working on a project that was sure to change the world of racing forever. He was determined to be the first person in the world to convert his stock fuel injection to methanol. After lots of hard work and people telling him it couldn’t be done, in 2002, Don decided to finally put his invention to the test on the track. The very first race with the methanol fuel injection conversion was a success! We are the innovators of fuel injection conversion, and have been improving the performance of racers all over the world ever since then. Additionally, we specialize in electronic engineering, so we have a much deeper understanding of what goes on behind the scenes here than most companies.
