Crashnburn80's Tesla Model 3 Performance Longer Range Build

Well this is a morbid turn of events.

Tesla driver who plunged his family off California cliff did so on purpose, officials say:

Had an electrical contractor check out the house today. Looks like I can drop my 2x 20A unneeded electrical heating circuits (for an unused baseboard) and swap in a 50A circuit for L2 charging without replacing the panel. That would take me from 16A charging off my 20A garage outlet to 40A charging on a dedicated 50A circuit, a 2.5x increase. To get that last 10A for a 60A circuit to get 48A charging (Tesla L2 max) sounds like it may be drastically more expensive. So I'd be happy with the ROI on the 50A. But of course it isn't so clean. My house being built in the 70s has a now illegal power input to the panel with no residential main breaker. There is a main breaker to a sub-panel, but not at the main input. The panel is also buts up to the edge of an exterior wall, which was originally unfinished, but now is finished, and as a result one edge of the panel cover is covered by 3/8 drywall, so I'll need to do some handy drywall work to clearance the panel to pass inspection. No numbers yet. But I'm pretty stoked for 50A capacity on my existing panel without an extremely expensive upgrade. The contractor is reasonably confident I can be grandfathered in if not replacing the panel on the power input situation.

 

My panel was similar (cira 72) no main disconnect but a 60A sub main for the 120V breakers
It was 4k-ish to replace and get new ground rods
I feel better about it now

 

So new circuit to the 50A breaker?

 

Removing 2 20A breakers and killing those off and replacing with a 50A breaker to the new L2 charging circuit.

 

These are interesting, they look very close to Uberturbines but are lighter weight forged aftermarket. They do have more spokes than the Uberturbines though, 13 vs 11.

Zink Wheels


OEM Turbines


Teslas OEM 20" Uberturbines are rather heavy at 32lbs. The Zink versions are 28lbs for the 20s and 25lbs for the 19s. On this style wheel specifically, I do like how the OEM wheels have the center lug cap vs the aftermarkets exposed lugs.

 

See if you can get to 5 sets of wheels on this rig?

 

Fortunately I sold the 18s. So... there is room for more? Part of me is tempted to pickup a 2nd set of new OEM Uberturbine take offs. Slightly heavy but I do like the look and when I wear out my set of summer tires I could swap them with the other wheels already loaded with the summer tires and maybe use the worn tire units for new all season tires.

 

The odometer only goes one way. You’re on 2 threatening 3. I say you get to 5 before you sell for a Y. Decent bet on my end.

 

Sigh. Did a dumb thing while not paying close attention. Back to the wheel shop, good thing I have that extra wheel set.

 

Wow. As of August 2022, the Model Y Performance has fake performance calipers in the rear. It gets the same brake calipers and pad size as the long range, but a plastic red performance cover making them appear to be a larger performance caliper. Rear rotor size is still a little thicker than the long range. Fortunately the M3P did not get that treatment, when I pulled my rear calipers, they were definitely the real deal and not plastic covers.

Per the article:

So I wonder if it really matters for real world performance or not.

 

The article greatly oversimplifies the matter.

Rear brakes typically do less of the vehicle braking than the fronts yes. This is because deceleration shifts the load toward the front axle, but vehicle weight distribution actually matters a non-trivial amount here. The Tacoma is roughly 60/40 weight distribution, meaning 60% of the weight is on the front axle in a static state. In braking the vehicle load shifts to put even greater effective weight distribution on the front axle. A few sources I've seen put that load weight distribution shift around +10%. So in braking in a Tacoma or similar, the effective weight distribution goes from 60/40 to now 70/30. The brakes ability to apply stopping force to the vehicle is force limited at the tire to road surface, effectively meaning that the rear brakes on a Tacoma can only apply 30% of the stopping force. Hence the reason why drum brake to disc brake upgrades don't offer significant performance gains in a Tacoma.

The Tesla model 3 weight distribution is 47/53, and the model Y is 46/54, meaning the cars are rear bias. So for the model Y, if you apply the same 10% weight distribution shift, you get 54/46, aka 46% of the braking is done with the rear brakes. Those numbers are pretty close to half. It isn't like the traditional front engine ICE vehicle with the heavy engine in the front skewing the weight distribution forward like most people thing of initially. The big brake kit not only has larger calipers with greater clamping force, but they are forged which flex less than the casts counterparts providing further increases in braking performance.

The Model Y Performance didn't get track mode originally, and really most the time driving you use regen for brakes. It isn't unless doing extreme driving typically needing a track that you will test the Tesla performance brakes. I'm betting Tesla figured people are not going to track the model Y, if so they'd opt for a model 3 instead and thus removed the rear performance brakes as a cost saving measure on the Y. I wouldn't be happy if I bought a model Y performance and discovered I had plastic fake caliper covers on the rear of my $70k vehicle.

 

What in the actual fuck. That price drop pushes profit down to $0 per car, while qualifying all cars for the $7.5k tax credit, meaning Tesla cars today are now $15k+ cheaper than a month ago. I literally checked pricing this morning for an unrelated reason, and it was unchanged, but it now reflects those new sale values. Apparently Toyota is the only brand not fucking me over on equity any more.

 

Yeah, long term evens out some. I don't plan on selling mine anytime soon, in it for the long run or until a new 3 offers significantly better performance. At least I didn't buy a used Tesla at $10k over new like they were selling over the summer due to high gas prices and long lead times on new Tesla cars. But after coming away from well over a $30k+ loss on the Jeep I didn't expect Tesla to intentionally chop block at the knees for depreciation on pricing. We'll see how that plays out long term.

I definitely have faith in the brand long term and have been eyeing the stock price. This price drop wipes out the profitability of their vehicle sales and should send the stock into a steep nose dive tomorrow far worse than its already catastrophic crashing tail spin. Best time to buy is when stocks are on sale.
