93FD

Not alot to report on the car recently. I’ve been daily driving it to work and getting about 16-18 mpg. Not exactly stellar. Unfortunately it’s the only thing I’ve got licensed and working. Odd eh? 3 cars and the FD is the only one I can drive.

Others in the garage have not been so lucky unfortunately… Ben and Damian both lost motors this month. Ben’s was not un-expected, since his car has done odd things since he picked it up. Damian’s car was running well, but he ate up another bearing, this time it was the front rotor bearing. Hopefully we’ll have that back up and running soon.

I still need to get some tuning runs done to verify my ~10psi (.7 bar) wastegate spring is ok to run with my current fuel maps. It more than likely is, but since the wideband overheats, it’s not easy to test. I have tried a couple different heatsink ideas for the sensor, but have not solved the problem yet. This may end up getting fixed over the winter, I might need to move the sensor into a better location.

Did get a bunch of other minor issues fixed, so that’s good, and the car generally runs pretty well at this point too. I do need to re-do pretty much the whole brake system since I’ve had lingering issues, and then ate up the pads/rotors at the FTL event. After that I just have a few things left to figure out and I will consider the whole project sucessful, even if it didn’t turn out exactly as I expected/wanted.

Finally made it to my first HPDE event on Saturday with Find the Line down at MAM. Car ran like a champ the whole day! I ran the wastegate spring (7.5 psi) because the boost control is still acting up. I’m probably going to just switch over to a manual system. I do also have a 12 pound wastegate spring on the way. Even at 7.5 psi though the car was making close to the same power as many of the others there.

I got close to 75 laps in over the day, and I skipped a couple sessions here and there so I could recouperate. Had a great time chasing Bryce around in his G35c and trying to follow Damian and everyone else around in group A. My best time ended up at 1:50.8, which is a couple seconds faster than my best time last year with the old motor and much better tires. The ones I have now are 20% less grippy than those (1G vs 1.2G+,) so my cornering speeds were down. On the plus side I can drive better. All in all alot of fun. Unfortunately Ben’s car did not do well, so he didn’t get to drive much. I did manage to give him a stomache ache on a ride along though…

I ate my brakes down to the squealers so I need to do something with those before I can hit another event. I really need to get some brake ducting going. I also figured out based on some track data that my injectors are at minimum duty for a bunch of the cells in my fuel map. I need to switch something up and start tuning again to get those back to a controllable range.
