Cross posting here for visibility. https://www.supramkv.com/threads/fuel-pump-control-electronics-internal-fault-error-at-track-day.32039/ Seemed like an odd issue. I was expecting it to complain about fuel starve or something, but a controller overheating was odd.

I ran the car for the first time on track yesterday and had an odd error pop up. I was in the 3rd session of the day and 8th lap of the session on a 1:40ish lap average when the car stumbled slightly coming out of a corner. I felt no real loss of power after, and everything seemed normal so I...

CMP being my home track means I'm also going to say it's rough on brakes. If your car can do 20 minute sessions and not cook the pads at CMP then you've solved any brake problems you'll have going forward. The wear rate is roughly double that of VIR or Road Atlanta. I took my Supra to...

I've been in a few car fires over the years, so I generally wear a fire suit even during HPDE. That plus a hybrid S is my usual attire. Of the last 5 cars I tracked only 1 had a real harness/harness bar and the rest had 3 point belts. The hybrid S works with any of them and was a pretty easy...

Seems like a good candidate for buying quality bolts from McMaster or similar and never having to worry about them again.

I'm assuming you guys are reusing your brake caliper/bracket bolts? I finished my swap to premium rear brakes yesterday and torqued them back down only to realize after they were marked as TTY fasteners. Since it's only for rears I'm not worried, but thought I'd ask as well.

Key word 😅

How bad would you like to get rid of it (aka, what price shipped to 29033) 😅 ? Also, rough guess on what it weighs?

Back in like 2009/2010 I used to know some of the HART guys. They would rent out NL for a day to test various cars and then reach out to their friends asking if they wanted incredibly cheap track time to help offset their rental costs. I would take them up on it every so often and it was...

I would agree with this. It's a good testing track, but as power increases it gets a lot more boring. RRR is a great track for sub 400 whp with aero, or sub 300 whp without aero lol

Having close to 1,400 laps there now vs a single day at RRR, I'm obviously going to be biased lol. There's a lot of tracks I really enjoy, and very few that I wouldn't go back to. Like, I wouldn't travel back to Grattan since I live in the SE, but it was fun to drive while I was there on One...

I would argue CMP is more of a drivers track but I think it's 6 of one, half a dozen of the other.

Get the little rubber caps meant to cap off vacuum lines and put them over the end of the brake line. Zip tie it closed to prevent any leakage, then set them generally upright so any bubbles stay at the top. I've done that method a lot on my cars when they would have to sit for more than a few...

Give Zebulon a call about their various endplate options. They have some fun stuff that works well. The splitter comments are true that a fixed splitter would cause more concern during transit to/from the track.

Zebulon is one of the gold standards (to me). I've looked at AJ Hartman, Ciro, Zebulon, Verus, and others. Consistently the cars with Zebulon aero seem faster. Anecdotal, but if I was building a TA car I'd be calling them for a splitter/wing/side strakes.

I have to imagine in either the Supra or C5 it'd be more fun. Probably more so in something like an EG. Any car you're doing something in the turn would be more fun than the C8Z given it was more of a blast down the straight(s) and then just kind of pedal it through the never ending corners...

Like others, I've told myself not to modify too much and haven't always kept that promise 😅 I'm prepping mine for S2 in SCCA TT which is basically camber, wheels/tires, drop springs, oil cooler, and maybe an exhaust down the road. Picking that class means I get good bang for the buck in...

290F is "fine" in the sense that the oil will do it, but I agree that it's a good idea to fix now before there's an issue down the road. This car does put some heat into the oil (makes me think of the C5 Vettes) and the one kit on the market is sized for the average track day enthusiast vs...

What temps are you seeing for oil?

I haven’t, but it wouldn’t be hard to do. I printed similar ones for my FR-S prior. The price would keep me from buying it since I’m not changing the tune. Im sure the amount of time that went into creating it is worth $65 to someone though. If you buy it/print it let us know. Or if you need...
