Vendor MPP At Global Time Attack Superlap With A P3D! Nov 8/9

[Perry]

We got track mode

Car is handling great on the MPP coilovers, and is even comfortable on the street. We have it charging at the track on a 50A circuit and Supercharged at lunch.

1:59 so far with Sasha driving. Faster than the gas cars so far!

What size wheels and tires are those? Include all sizes and offset, please.

More photos of the aero. Prototype from Maier Racing. It definitely improved the handling on track, and could have knocked off 1-2 seconds by itself.

Maier racing makes some incredible stuff. One of my good friends is pretty tight with the owner and his son. I did not know they were getting into the model 3 game.

These are the wheels I used, they fit well on a Model 3 LR, but on a P3D they need 5mm spacers in the front (and you can put them in the back too for symmetry).

So those are 18" huh? They look larger than that. What about tire size?

But would you say that for the P3D- without the thin rotors, or the MPP rotors, there would be no need for the spacers since our wheels are 3mm more out?

I also ran a set of 18x9.5 +35 and I didn't need to use spacer in the front with stock suspension. What was the spacer for?

What size PS4s did you end up using?

post #12 has a pic showing the tire size of 255/40/18

It would be cool to see the full build once you guys get a chance.

Here's the video from my fastest lap, Sasha and team will have their full event coverage video up soon!

Awesome! We've just finished the event recap post on the website, here's a link:

MPP Competes In Global Time Attack With Performance Model 3, Sets Fastest Time, Gets DQ’d For Being Electric!

And here is the full video. It's worth a watch!

I love it. Head down, humble, no protest to the last minute podium disqualification, come in next year with the EV rules "eased up" and show them THE FUTURE. Subbed and liked, you guys did a great job.

Thank you! Subaru guy may have won this round, but he only accelerated his demise. We bet there will be more Tesla's there next year looking to dethrone him.

 

[Oyster Bait]

Did you leave the MPP stability defeat magic in place with Track Mode? Does Track Mode do the same job - for the Performance model - as MPP's device does for the rwd model?

 

[Daniel in SD]

Well done!
So, any ideas about how to improve the car?
Any thoughts on how much time could be cut by having taller gearing? The market for that modification would probably be super small.
The rules for enthusiast class seem a little odd with regards to engine modifications. It says that the car must be a registered street driven car but I doubt any of those Subarus are actually street legal in California. Like you said they’re probably 500+ HP.

Running taller tires would effectively improve the gearing for high speeds. The 18" wheels would be great for a tight course or autocross but actually hampered us by increasing the motor speed by the percentage of height difference of the tires. We would have benefitted from a proper racing wing, once we added the front spoiler the car became loose at high speed. A wing would balance it out nicely, but it is Cameron's daily driver so that won't be happening. We are working on plans for a properly built race car to upset much higher classes than Enthusiast AWD.

So you switched to 18" from the stock 20" with the PUP, or did you order non-PUP?

FWIW considering switching my PUP 20s for something lighter as I'm not a huge fan of the ~17 extra pounds per wheel.

 

[gilscales]

he 18" wheels would be great for a tight course or autocross but actually hampered us by increasing the motor speed by the percentage of height difference of the tires.

I see that the Tire you guys ran is approx. 2% smaller in diameter, in hindsight would it have been better to go with a 45 sidewall for a 2% increase in size, do you think that a 4% motor speed reduction would have helped as well as the increased load rating of the tire?

A larger rear diffuser could also add some downforce at back. Agree a proper wing would be good too. I would probably use both, in addition to a longer front splitter.

Cameron went with a 18 to get the lightest wheel. (I think I don't see red calipers, so no PUO?) As Sasha pointed out, if you go with a wider tire it offsets some of the weight advantage of the smaller wheel. His 275/19 on Advan racing wheel came out about the same weight as the stock 235/18.

FWIW considering switching my PUP 20s for something lighter as I'm not a huge fan of the ~17 extra pounds per wheel.

Same. Long term I'm not using the heavy PUO wheels. Leaning to 19x9.5s for track use due to the largest selection of racing/soft compound 265-19 tires available.

(* PUP is confusing because many people used it to refer to the Premium interior option before. Also the correct name of the wheel, tire, brake, etc., upgrade on Model 3 Performance is Performance Upgrade option.)

A taller tire (or gears) would move more of the speed range of that track under the torque curve of the motors and therefore should be faster, everything else being equal.

That car has the Performance Upgrade Option/Package. You can see the red calipers when they pull in to the Supercharger.
