Formula 1000

Not to be confused with the publisher of services for life scientists Faculty of 1000.

Formula 1000 is an open wheel class of Formula car racing by the Sports Car Club of America (SCCA) where a 1000 cc motorcycle engine is used to power a single seat, open wheel race car with full racing aerodynamics and suspension. The F1000 class, also called FB, was created by SCCA in 2006. Similar SCCA classes include FA (Formula Atlantic), FC (Formula Continental), FF (Formula Ford) and FV (Formula Vee). Motorcycle power formula cars have been popular in the UK for many years and have been a very successful class.

Stohr F1000

F1000 cars can be purchased new and ready to race for $30,000 to $65,000. SCCA rules also allow for converting an existing Formula car (e.g., FC or FF) to meet F1000 requirements. Conversions using an older Van Diemen chassis with a used motorcycle engine are estimated to cost $18,000 to $24,000.

Formula 1000 racing is mainly an amateur, club-racing series attracting serious enthusiasts. The car can provide drivers with their first insights into how a racing car feels to drive and how to properly set up a car, or it can provide a relatively inexpensive way for drivers to campaign purpose-built racecars for many years.

Manufacturers

Manufacturers of purpose built Formula 1000 race cars and manufacturers of Formula 1000 race car conversions are listed below in alphabetical order. A Formula 1000 conversion involves the modification of an existing formula race car to meet current Formula 1000 rules. One of the major changes involved in a conversion is replacing the original engine and drive train with a 1000 cc motorcycle engine using a chain drive train. Other modifications may include chassis frame changes, suspension changes and the addition of an aerodynamics package consisting of front and rear wings with a floor pan diffuser.
