Fonse Performance was established in 1975 by Al Fonse Sr. We are a family owned and operated business. Al Sr. and son Al Jr. run the shop and do all of the research and development, designing all of there “Dyno Proven” engines.

We are located in Southern New Jersey, 15 miles East of Philadelphia and 40 miles north of Atlantic City, New Jersey. We are conveniently located near the Delaware River, Atlantic Ocean, Atco Raceway, Englishtown Raceway, Bridgeport Speedway, East Windsor Speedway and Maple Grove Raceway.

For over 3 decades Fonse Performance has been building quality HIGH PERFORMANCE ENGINES for all forms of racing and pleasure use, including: pleasure and racing boats, street, strip and circle track cars. Our experience in racing came from owning race cars and boats we’ve have built for our own use and for our valued customers.

We take pride in our engines and parts, we only sell what we know and what we have proven in our “State of the Art” Machine Shop, which includes a Superflow SF-902 Engine Dyno.

Our primary focus is customer satisfaction. Creating and maintaining long term customer relationships comes naturally at Fonse Performance with our philosophy: “We are here for you when you need us.”

With over 30 years in the business, we have dedicated our company to top quality engine building services MADE IN AMERICA.
