I forgot how much I missed doing pulls and hearing the blower scream. Update on the rear mounted boost reference fuel pressure regulator is that it seems to be working fine. The way it came from ZZP it was producing about 40 psi fuel pressure. We ended up having to crank the differential fuel pressure up to 60 psi because I was running out of injector. This is interesting because before on stock ECU with Trifecta I think we only got to about 80% duty cycle and I was running stock fuel pump with stock fuel pressure regulator. As far as power adders the head is the only difference and it shouldn't be real significant IMO because my last head was port matched as well. I think between the L61 ECU and the wasted spark ignition with two cylinders sharing a coil something wasn't quite keeping up. Be interesting to get it on a dyno.

1300 cc injectors are ordered. Hopefully get here this week. It may be unrealistic but there is an autocross event this Sunday I would like to make it to. Just need to get the larger injectors installed, car aligned, and the tune dialed in enough to rip around on it. I'm thinking I'll run around 40 psi differential injector fuel pressure. At what point does pressure get too low for injectors to spray properly?

Just read this again, 40psi differential pressure would be 55ish psi, thats more than enough. Ive heard of people running as low as 35psig.

Just installed a Haltech HT-010204 intake air temperature sensor yesterday evening. My PLX SM-AIT sensor with DM-6 gauge seems to have turned into a POS for some reason. At first I thought I just had sensor noise but now that I have installed a second air temp sensor I've also discovered the PLX isn't reading correctly even though the reading stays steady with ignition-on/engine-off. I would really like for my temp gauge to work but it's not really necessary now because the AEM is getting a accurate temperature signal from the Haltech sensor and I can see the temperature that way. Instead of buying new parts trying to fix my IAT temp gauge maybe I should just save that money for one of these bad boys down the road.

Wallet homicide, but in your case, it was murdered a long time ago.

Second autocross of the season but first autocross that I didn't have problems. First event I had issues with the AEM killing power to the engine because I had my oil pressure sensor calibrated wrong and it thought I was dropping to 20psi at 4k rpm in a sweeper. All fixed now. Haven't done it yet but will be interesting to pull the logs and see what the oil pressure did in the corners. As even though my sensor was calibrated wrong my oil pressure was still consistently dropping in the sweepers just probably not to dangerous levels. Running a quart over now so maybe no drop at all but we will see.

Had a hell of a time getting a clean run today. Kept hitting a cone in the turn around slalom.

That trailer is perfect for my car honestly. The single axle is a 5,000lb axle. Being aluminum it is also light enough to wheel around by hand. I really only notice it is back there if I am trying to maintain 75mph up a hill on interstate. Pulls easy and is maneuverable to get around hotel and fast food parking lots.

I had multiple camera issues so ended up only with my phone footage which I really only had setup for audio. Drove alright though. Only got beat by 1 other car that wasn't a Formula Cart. Disclaimer though the first heat had to deal with moisture on the course.

Were all those FSAE guys sharing the two karts they brought? I just checked out their website, pretty sweet cars.

They brought 3 carts. 2 were running. One of those two ran the course once and quit working. So everyone who drove actually ended up running the the Lynx 2.0. I think that timing sheet above is showing Lynx and Lynx 2.0 but that is probably because that is how they registered even though everyone that ran ended up using the 2.0. They were just hot lapping the thing lol. And even it they broke the starter somehow so they had to push start it though they tried to keep it running the whole time it did not like to idle.

Almost makes me wish I was on FSAE but all that work and never getting to drive the car doesn't seem right to me. I dont think my school ever took theirs to Autox.

I kind of wish I would have joined ours back at KU but they were always working in the lab on Saturdays and hanging out with a bunch of enginerds on Saturdays was not my idea of a good time in college.

At smaller schools, it seems there is usually just 1 or 2 guys who do the majority of the work on the car and then 30 students will show up for picture day to prove they were on the team. I've seen this at three Michigan universities and they weren't named U of M or State.

I was off by a semester so I missed out on the SAE projects. Biggest disappointment of college.

I would do it in a heartbeat now. But at the time I was more concerned about having spare time to party.
