750 Formula

Descriptions, regulations and registration for 750 Formula.

Raceparts 750 Formula Championship

A sports-prototype racing car with offset driver position and a small passenger space. Many cars have been individually designed and built by enthusiasts over the years but there are also some series production and limited production cars available as well as a good second-hand market. The regulations are designed to encourage close, competitive racing while controlling costs. Regulation stability means that cars hold their value well. The cars are lightweight (minimum weight of 375kg) with excellent grip and balance. 750 Formula is believed by many to be the ultimate in fun, low cost racing.


Engine

The formula uses the ultra reliable Fiat 1108cc ‘FIRE’ engine in fairly standard trim to keep costs down and reliability up and with a mandated cam to even out performance. Tuning is restricted to balancing the engine, lightening the flywheel and skimming the head. Induction is restricted to one carburettor choke while the exhaust system is free. All this gives a power output of around 95-100 bhp and a nice wide power band, which, combined with the light chassis weight, gives average lap speeds of 85-95mph, making the cars a second or so off the BTCC lap times at most circuits.

Suspension

Design is free, but cars must use a live rear axle, or a FIAT transaxle complete with the standard 5 speed gearbox and final drive and independent rear suspension.

Brakes

Choice is free.

Transmission

4-speed plus reverse or 5 speed if using the FIAT transaxle. LSD and all other traction control is prohibited.

Tyres

The formula uses control Yokohama slick tyres which tend to last the best part of a season and are also available second hand from the Sports2000 formula. Competitors at the pointy end of the grid will probably use 1.5 sets per year with tyres costing around £475 per set fitted. There is a Yokohama service truck at most race meetings. Wets are free.

Rounds

There are 14 rounds in the 2017 season, spread across seven 'double-header' race weekends. The best 12 results count for the championship.

Classes

In addition to Class A, in which all competitors compete, there are two other classes. Class B is for drivers who have not finished on the podium, in the top six in the championship or won the Class B Championship in the last five years. Class C is aimed at colleges who are encouraged to enter teams. There are trophies for the first three finishers in Class A and Class B.
