BRZ/86 – Black Dog Motorsport

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.

E85 Tune

Well, I finally bit the bullet now that I have a working twin fuel pump system and had the car tuned to run on E85.

HUGE thanks to the team at Parramatta Vehicle Services for their excellent service and knowledge. 145KW at the wheels. I`ll take 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.

Try Again

Having all sorts of issues with the Twin Fuel Pump Control Board, so I did the mature thing and threw it all out. Time to start again.

Simplified the whole idea, got rid of the op-amp, and I am just using a single MOSFET. Bench testing of a bread boarded prototype is showing promise.

I have some new boards on order which will be here in about 3 weeks. I have to order a new MOSFET as the ones I have don’t turn fully on until 15.5V which is too high, although they will do for testing purposes.

Stay tuned.
