We’ve been working hard. Not very hard at updating the website (though I still tweet occasionally) I admit, but in the workshop we’ve been busy.

  • The floor has come off, been cleaned properly, slightly modified with a belt sander and refitted. The bulge seems to be better now.
  • The camera was tested, sent off and testing by DogCamSport, and is now back with us and working. All fitted and ready to go.
  • The silencer was inspected, and the new packing is holding up well. Hopefully no noise problems at Snetterton!
  • We have had a chat with Specialist Components (the ECU people) with datalogging and video evidence of the misfire, and we think it’s more likely a mapping issue – the fuelling going rich or lean at various points. So we’ve fitted a lambda sensor, and will be able to log the throttle, RPM and fuelling to see what happens. Hopefully this will help reduce any misfires. We’ll also make sure the battery is fully charged just in case battery voltage is the cause.

The car is a Formula Three car from 1998, manufactured by the Italian company Dallara. As such it is referred to as the Dallara F398. As with all F3 cars from the last twenty years it is a carbon monocoque car, using a stressed engine on which the gearbox and rear suspension is hung. At both ends of the car, suspension is double wishbone, using slick tyres to provide grip. A full aerodynamic package, with wings, diffusers and airflow conditioners is used front and back to enhance the grip of the tyres. The rear suspension uses three springs (one in roll, two in ride) and two dampers to provide compliance, but at the front a single damper and coil spring is used for ride (a monoshock arrangement), with roll stiffness (compliance?) provided by the monoshock assembly sliding laterally against a stack of belleville washers.
