This section contains a lot of the technical information you will need to restore and maintain your Formula Ford. Remember, do not hesitate to ask for help! The two photos below show what a typical Formula Ford (this is a Crossle) looks like with its bodywork removed.

All Formula Fords are mid-engine, open-wheeled, single seaters with the 1600cc Ford (‘Kent’) engine. They are built to rigid class rules by specifying dimensions for all critical components. While engine modifications are limited by class rules, careful engine tuning produces power outputs up to 115 horsepower, compared to 86 horsepower for stock engines.

  • Top Speed – depends on gearing but can be more than 130 MPH (210 KMH)
  • Chassis – welded steel tube spaceframe – monocoque construction is not permitted
  • Length – approximately 13 feet (4 metres) overall
  • Width –  approximately 6 feet (1.8 metres)

 Engine Information

Pegasus Auto Racing (web site) is the exclusive US importer for FF1600 (‘Kent’) engine parts manufactured by Formula Ford International to original Ford Motor Company specifications. Click here for their technical specifications.

The KENTLives web site (here) has a lot of very useful information. For example, this page (here) has some detailed information specifically about the Kent engine.

You can see a a short video of a ‘Quicksilver’ Formula Ford engine running on You Tube here . (The video isn’t the best quality but you can at least hear what a typical Formula Ford sounds like.)

Gearbox Information

Hewland Engineering (web site) have supplied the majority of the Formula Ford gearboxes from the beginning. The Hewland Mk 8-9 was the standard gearbox on most Formula Fords up until about 1989, when the Hewland LD 200 was introduced. Technical manuals and other useful information is available on the Hewland site as well as on the Classic Formula Ford (UK) web site (here). Links to two of the manuals are available below:

  • Hewland Mk 8-9 Manual (here)
  • Hewland LD200 Manual (here)

Tire Information

Some race organizations permit full race (slick) tires while others require ‘street’ tires with some tread pattern. Tires are a very important factor in lap times. Usually, you will need one set of tires for dry conditions and another for the wet. There is a lot of tire information available from a lot of different sources. The following sites will give you a starting point but make sure to ask!

  • American Racer information (here)
  • Goodyear information (here) Note: When this page opens, click the tab for ‘Eagle Sports Car Special’ and then select the ‘Download Tire Guide’ button.
  • Hoosier information (here)

  • Dampers (Shock Absorbers) – coming soon
  • Springs and Anti-roll (Sway) Bars – coming soon

Set Up Information

No matter how good a car is, if it isn’t get set up properly it won’t lap as quickly as it could. There is no substitute for experience when setting up a racing car but even a ‘rookie’ can get close if they follow a systematic procedure. Dave Weitzenhof won the National Formula Ford title at the SCCA Runoffs four times and now races a  F2000 car. He knows a thing or two about how to setup a single seater, and make it work.
