Did I hit a nerve there? :) You're proving my point either way. The delta at LRP is similar to RRR in a lot of ways and that's not a track known for causing heating issues. Yes, you make 600 whp, we get that. I know the fuel requirements for that also. I have no clue what pump setup you...

Tracking in the SE is not like tracking in the NE. 80F+ ambient is late October to early November here. 147 in a straight also depends on what your starting speed was, because if you're referencing LRP then isn't the starting speed around 90ish? CMS has the entry to the banking at 40ish mph...

All nannies off every session. And the car is completely stock driveline wise. I'm very comfortable driving sideways and the car was quite happy to gently rotate if I squeezed throttle a bit too much so I know it was off. Having raced cars without AC in endurance series some years ago I...

There's a bit of math that would go into the sizing, but the simple version is what you said. The larger hotside of a larger turbo means less restriction. Boost is simply a measurement of restriction for forcing air through. Then you also get a turbo that's working in a more efficient area...

The fan also doesn’t run at speed. It will help with cool down if you come to a stop or are below whatever the mph is for full off, but at track speed it’s not going to help. I just did a day here where it was 88-91F or 32-33C and my coolant temp was pretty solid at 90C and oil temp never went...

The gearing you mention is what kept me from pursuing a 981 GT4. I owned a 981 GTS with the PDK and was able to keep up (until the straights) with a 982 GT4 manual. The PDK gearing and shift times made my car faster everywhere except straights. The owner of the GT4 went out and bought a 982...

If you notice, I said "has much overlap" not "has no overlap" ;) I know multiple people who have GT3's and Supra's both together or separately also. My point is the general crowd of people who are buying AND tracking a 3RS doesn't always pay a bunch of attention to the Supra. It also requires...

Either way, the path forward is go to the next event and see if it happens again. In the meantime I'll look at the module and see if there's any obvious issues with it. The print is "free" and I can look at a fan for it just in case.

I don't think the price difference is overlooked here... I also don't think the venn diagram of people who are actively shopping for a 3RS has much overlap with people who are shopping for a Supra. The few people I know with 992 GT3's or any recent 3RS have all either found them via brokers or...

Interesting! The fact it's called something else in BMW world makes sense why my general searches didn't pop anything up. I was planning on looking at the module to begin with, so knowing there are ready made 3d prints and plans to cool it are nice. A bit more looking, it appears you can...

I saw that as well after I did some more looking. I'm going to take a look at it and see if there's something going on that's obvious first. If it happens again I'll know I can clear it and continue on, but I'll also take it in to use the warranty. Depending on the part, I try to use the...

One piece that's really overlooked for the GT3/RS cars is just how good their gearing is. The downforce is bonkers and with the engine really adding grip to the rear it's a complete package, but that gearing means you really don't drop out of the power band at any given point and it's always on...

I have the KSP spacers off Amazon. They had a sale going at the time so they were $25/$30 when I got them, but they are well made and way less expensive than name brands. I've long used eBay or Amazon, or even made my own when I had easy access to a lathe...

I only felt the car stumble once and it was for less than a second. It would seem odd for that to cause it. The car had 5 bars of fuel still, but likely around 4 gallons down from full. I’d think if the pump and not the controller was overheating that we’d see other people with the same code a...

No different than NCM in my mind for walls. There are a few sections with basically zero runoff before a wall but it’s also generally not a place you should be out of control if you have any semblance of experience. NASCAR banking is always a hoot though, but can also be intimidating given the...

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.
