I have a draggy coming in next week, i plan on doing some testing 0-60 from 95% down to 10% with my new M3P in 50-degree weather just to see how consistent it is. I'll report back after.

I wish I could find the link because it showed actually a different serial number for the latest version of the model y performance rear motor. May have had hairpin windings as well
Sorry yes of course I meant part number not serial numberSurely you are not suggesting that two motors aren't the same type because they have different serial numbers, are you? Do serial numbers on motors not work like serial numbers on everything else?
Stock or aftermarket wheels/tires?I have a draggy coming in next week, i plan on doing some testing 0-60 from 95% down to 10% with my new M3P in 50-degree weather just to see how consistent it is. I'll report back after.
2022 M3P stock wheels, everything will be stock. For added insight, i weight 190 and will have another 30ish pounds in the car from a car seat. Probably does not matter but figured i would add that in there. It will probably take me a week to do all of the testing. I figured it would be best to do 3 runs and Take the average at each state of charge?Stock or aftermarket wheels/tires?
Sounds like a reasonable plan to me. I’ll be looking forward to your results.2022 M3P stock wheels, everything will be stock.

Keep us posted. SB local here as well!2022 M3P stock wheels, everything will be stock. For added insight, i weight 190 and will have another 30ish pounds in the car from a car seat.

Did you mean tire diameter? I would expect wheel diameter only matters insofar as it affects the total wheel+tire weight.So I am also interested in another comparison: how would wheel diameter affect the accelleration?
People do compare the Y to the 3 and while Y is heavier, it also has a larger dia wheels.
And I remember seeing a video on youtube where the owner put light 3 wheels on Y and got better accelleration, but some of that effect might also have been down to smaller dia wheels giving better accelleration? Not sure how that would pan out over a 0-201 meter (1/8 mile) drag race though.
I do however rembmer the guy dragracing a S P100D Ludi and he put largr dia wheels to win drags, but I guess he ran 1/4 mile drags and I guess then the torque mighe be falling on the curve more...
I will! the draggy comes in Tuesday. When did you pick up your M3P?Keep us posted. SB local here as well!
Oops...I made the same typo. I meant "larger-than-stock diameter tires" (not wheels).Did you mean tire diameter? I would expect wheel diameter only matters insofar as it affects the total wheel+tire weight.
Given the top end power limits of the Model 3 (and most EVs), for 1/4 mile (or longer) I would guess larger-than-stock diameter wheels could be overall beneficial, even if they weigh slightly more and are slower off the line. This is assuming you find a way to fit significantly taller tires. I'm doubtful that adding the 0.5"-1" of extra diameter that might fit with the stock suspension would make a meaningful (consistently measurable) difference.
Actually taller drive ratios would be a neat mod to try. Not something I personally would bother with as a mod, but if I had the option from the factory for taller drive ratios that gave me stronger highway speed acceleration, at the cost of 0-60, I would have taken it.

I do not have scan my tesla; do we really think it is needed? I'm not opposed to getting it. Is the assumption possibly that they upped the voltage draw? Or do we just need as much data as possible? furthermore, the test is obviously kind of skewed because it will be done over about a weeklong and temps will be different every day.Do you have Scan My Tesla so you can measure battery temps and voltage? You can get everything you need for about $100.

The only problem i see is that even if we plot this data (Battery voltage & temp & whatever else we think is valuable) will not change the fact that they will be different with each day. Trying to get as close as possible is the best option i see? The 3 runs should up temp i would assume?To me it seems from reading this thread that if you don't have near identical quiescent battery voltage, battery temp and external temp readings right before each of your runs comparing with extra weight and without then one side or the other will complain that your test is invalid because the battery was in a different state of readiness for some runs than others.
I guess this is not the thread that maybe it should be posted in, although it will be. The test that's going to happen just sprung out of curiosity. I am neither going to reduce weight or add weight. Just seeing with the new 22 M3P if acceleration has stayed the same or improved in some fashion, either SoC or temperature. I see what you mean though.I'll also add that this is not really a valid test. If Tesla does limit acceleration than means that reducing weight will not make the car accelerate faster after some acceleration limit is hit which is the same as saying the car won't accelerate faster after some weight threshold is hit because lowering weight increases acceleration all things being equal. But that's not the same thing as saying that adding weight will have no effect. It really depends on where that theoretical weight threshold is and the car's tested weight relative to it.
For example, let's say the theoretical acceleration limit has an equivalent weight threshold of 4,500 pounds. (And let's ignore the differences that location/distribution of the weight creates.) What I mean by this is that at that weight if the acceleration limit were removed the car would sill accelerate at the same rate to 60 MPH as if the rate limit were there. If there were no limit then lower than that weight would be faster to 60 and greater than that weight would be slower. But if you go over 4,500 pounds the car will still accelerate slower regardless of whether there is a acceleration limit or not! Since we don't know where that equivalent weight limit is your test may be invalid because when you add weight you may go over it.
In other words to really test this you need to reduce weight not add weight.
I know it's truly not a valid test, but we will be able to draw some form a conclusion from these tests.I'll also add that this is not really a valid test.

All good, i should have been a little clearer haha.Oh sorry, Kaz93. I thought your test was to try to prove or disprove the argument that was happening earlier in the thread. My mistake!
