Some of the modifications we are making to our Ginetta to compete in the I/FMS Class

The Record

During the 2008 Speed Trial Season we will try and set two records with our Ginetta G4:

- I/GT (1L Grand Touring) - currently standing at 121.779 mph

-I/FMS (1L Fuel Modified Sports) - has an open record.

In 1964 Graham Hill, two-time Formula 1 World Champion, test drove the Ginetta G4 and reached 110 mph with a 1.2L engine, barely tuned, with a single carburetor. This, together with the input from several G4 owners and specialists, gave us the initial confidence that our Ginetta G4, with a finely tuned race engine, set up for top speed, would be capable of pushing through the air quicker than has ever been done before!

Different Car Classes

The Southern California Timing Association (SCTA) and the Utah Salt Flats Racing Association (USFRA) recognize an astonishing amount of car classes, ranging from Streamliners to Production Pickups to Highway Haulers to motorcycles in various shapes and forms. There is a further breakdown depending on the type of fuel used and whether or not the car is turbo/supercharged.

The classes are named by abbreviation, eg, /GS (Gas Streamliner) or /BFR (Blown Fuel Roadster).

Each class is then divided by engine size. The engine size is defined by a letter ranging from K (500 cc / 30 cid and under) t

o AA (over 8210 cc / 501 cid) and some vintage engines like pre 1953 V8 Flatheads.

For example: F/BFS stands for Blown Fuel Streamliner (/BFS) with a 2.01 to 3 Liter engine (F)

Have a look at the SCTA website for a list and description of all the different car and engine sizes.

Our Classes

I/GT class:

SCTA defines the GT class as follows: “Series production sports cars and coupes, as well as limited production cars by a recognized automobile manufacturer, which are primarily intended for comfortable high speed touring.”

The GT class falls under the Production Category. This means that there need to be at least 500 vehicles produced and GT means it needs to be a 2-seater sports car. The class rules also state that no aerodynamic improvements can be made (the car needs to have the original head lamps, gaps, air openings,...) and if the car is a convertible it needs to run with the top on - something we will need to do.

Although engine tuning is of course allowed, the engine needs to be of the same configuration as the original.

I/FMS class:

“This class is intended for production sports cars as accepted for GT class which have been modified to such an extent as to make the vehicle illegal for the Production Category.”

The most influential factor in land speed racing is aerodynamics. Competing in the Modified Sports class gives us the opportunity to optimize the already very aerodynamic Ginetta G4. Body modifications are allowed are from the firewall forward only, but additions like tonneau covers, air dams, head lamp covers, spoilers, head fairing (rear fin) etc are permitted… effectively turning our Ginetta into a wide-bodied streamliner. Doing this should allow us to go quite a bit faster then in the GT class and we hope to set a competitive benchmark for the I/FMS class.
