P3D+ Street/Track/Time Trial Build

[Clivew]

I appreciate you explaining it more in-depth. I will compare rotor temperature with and without the duct cover to see what (if any) difference it makes.

Again, I applaud what you are doing with the car, and the effort you are making to document what you've done, thus allowing comment and discussion on how to improve the car. I look forward to the results, and it may also be worth logging temps with the hose disconnected from the inner end, where it attaches to the disc duct.

Do let us know how those Federals perform please.

Do let us know how those Federals perform please.

I was quite happy with them last event. Ran 3 days and they only wore 1/32nd. Wear was even, ran a PB lap time, they're quieter and smoother than the Nexen's they replaced. For the price I think they are a great value. Take a lap or two to warm up but I never felt them get greasy.

 

[MasterC17]

Well my goal for the weekend was to hit 3:00 on VIR Grand, and I was able to obtain that! I set my PB with only 9 laps of VIR Grand under my belt. Being such a long track (4.1 miles), you have about 2 chances to set a PB from 100% SOC (you use 10% per lap). I started with 90% SOC, so after my warm-up lap I knew I had one chance to do it, and I managed to get it done. The next lap I hit traffic anyway, so it worked out.

The car performed very well. The only issue I had was brake fade into turn one immediately following my PB. I actually got the brakes over temperature warning and SMT showed temps over 1200f. Fortunately, I am working with Essex for a permanent solve for that issue. It seems the rotors are just too thin to handle the mass of the car, which isn't terribly surprising. That being said, it only became an issue when I started pushing 10/10ths.

Here's a video. I mounted an external microphone under the frunk. I didn't consider how much noise the tires would be making, but the motor sounds pretty cool. May need to relocate it to the rear drive unit area. Also overlaid the data from SMT which is pretty sweet!

Wow! That's seriously impressive driving.

Thanks! I only wish I had a 200kWh battery pack so I could stay out there longer

 

[Dangerous Fish]

That's great. You should try it in dyno mode next time.

Out of interest, what app are you using to record the SMT display?

Android App called Vecorder.

I'm guessing Dyno Mode would make me slower and more likely to crash lol

Impressive driving! Love the sound of the motor and tires.

Thanks, I'll try it.
Depends on whether you felt the TC was intervening much. Someone with a RWD Model 3 tried it on atrack and reckoned it was faster.

I definitely think the standard TC would be slower than Dyno Mode, but I don't think Track Mode intervenes in any way that would slow you down. If anything, I think it makes the car faster by optimizing cooling and power output. I spent all day working with an instructor Saturday and he was incredibly impressed with Track Mode and how well the car could put power down and pull out of corners. It will absolutely let you get sideways, but it will intervene if you're completely out of control.

The motor sounds very cool! It's kind of unfortunate you can't hear it much from the interior. I figured the video would be a lot more fun with something other than wind noise haha

Track mode definitely intervenes too much in some types of corner. I've experienced it and it's quite frustrating at times.
The problem is we can't have track mode and dyno mode at the same time (AFAIK) so what we might gain with dyno mode we'll lose as the drivetrain warms up.
What we need is Track Mode Plus with adjustable TC/SC.

I recall Elon had mentioned it would be user adjustable at some point, but it definitely doesn't look like they ever got around to it.

What types of corners do you feel it intervenes too much in? I noticed once the SOC drops and the motors heat up the car has a harder time putting power down unless your steering angle is straight, but I think that is a thermal/battery limit and not a traction control one.

There are corners where you may need to slide the car a little in order to keep up the momentum for the exit. This is where I feel it's holding back somewhat. Track mode allows some sliding, but not enough for some situations.

Track Mode V2 news just came out today actually...

I guess I just had to say nay and Elon blessed us with new software in response lol

Do you happen to remember what gopro settings you were using? The sense of speed on your video makes it way more exciting to watch than all others I've seen, including mine. I think I may also try to find a good external mic, in addition to turning the "hypersmooth" stabilization feature off. Solid laps!

Next event in less than two weeks. Preparation underway.
