Repairs

Unsurprisingly, taking a production car and flogging it to death on a racetrack can lead to a few issues from time to time. Having said that though, this car has been remarkably robust.

Engine wise the car has been bullet proof. Do not let anyone tell you these Boxer engines are not reliable. If you keep up the maintenance, you will not have a problem. It should be noted though that I do run an oil cooler and I change the oil after each event. I also run an oil surge baffle in the sump.

Outside of normal maintenance, the only thing I have had to replace are the wheel bearings on the driver’s side. This side is usually the loaded side at the tracks I frequent the most, and even though the car only has 29000 Km`s on it, they were basically Catus.

Round 3

SMSP Amaroo South

Round 3 of the Prospeed Racing NSW Supersprints was held on the 26th of April and was a great day with a great turn out

The day started with a heavy fog with the promise of a nice day once it cleared.

The car was a Jet, and it was so much fun to drive it is difficult to explain it adequately.

I was happy with the time I managed although having not been there before I don’t know if it is good or bad.

I ended up pacing 30th out of a field of 70+ with a time of 1:05 which i think is reasonable for an NA 2ltr, it certainly felt on the quick side. Going back next weekend for the CSCA Round. Can’t wait for that.

Fuel Surge Progress

After some false starts and setbacks, I have a functioning Control Module prototype fitted in the car and it is working beautifully.

The basis for the unit is this Voltage sensing Relay Module I bought off AliExpress. Added to an interface with a Buffer OpAmp fitted.

I am leaving the home-made prototype board in the car for prolonged testing and should the results be as expected, I will have the above professional boards manufactured.

Check out the YouTube Channel for details.

Progress

Things are finally coming together with the Twin Fuel Pump Control Module project, with the new design tested on a Bread Board satisfactorily.

I have changed the MOSFET in the design to one with a drive voltage of 10V, which necessitated the inclusion of a 10V Voltage divider, other than that, it is the same as in the last post. Boards are being manufactured now.
