I just wanted to chime in and say "thanks" to everyone for shifting the discussion back toward "healthy debate".

I don’t keep up with Plaid stuff all that closely, but aren’t there stripped Plaids running like half a second faster than stock? Every random 8.7x video I have seen was only accomplished with lots of weight removed, no?the difference is negatable on 0-60mph times. And you're also talking about an absurd amount of weight.
get whatever lightweight parts you want to, go to the drag strip, run a few runs in the OEM configuration then install the parts and do it again.
even when you cut an entire car apart, it doesn't make that much of a difference. boostedboiz removed 900 pounds from a plaid by even cutting off the body, and used a driver that weighed 80 pounds iirc (short dude) and still only got 0.02 faster in the 1/4 than Roy's plaid that is much heavier.

I was really just checking if the Plaid example was being cited as evidence that the cars are deliberately software-limited. Given the acknowledged traction limitations, and the significant improvements in measurable performance (both in time and in peak g) after modifications, I am not sure such evidence would apply.Completely gutted and the cars have been ruined in the process. The systems on the plaids are different than the 3/Y; when you add stickier tires and remove that much weight, you can see the G-forces increase on a launch with a plaid. With the 3/Y that doesn't really happen, everyone stays right under 1g, or like the 2019's I peaked a single time at 1.1g. The Plaids see +/- 1.3g, then upwards of 1.7g after gutting and tires.
They're software limited to a certain % of the battery pack's output. But that's no different than a car company putting a rev limiter on an engine.I was really just checking if the Plaid example was being cited as evidence that the cars are deliberately software-limited.

Honestly it sounds like the plaid example isn’t particularly relevant to the question of whether a Model 3 deliberately limits acceleration (whether linear or angular) to a fixed amount regardless of weight.They're software limited to a certain % of the battery pack's output. But that's no different than a car company putting a rev limiter on an engine.
Also a plaid has 400HP at 0mph for launching, and it does a mostly linear ramp up to 1000HP at 60mph. That's because of both traction issues on street tires, and if you put something like slicks on it and did a hard launch and it had full power at 0mph, you're going to start breaking stuff on the drivetrain. This is the same as a timing/fuel map on a gas car, except no one can seem to crack the system and modify it.
The thing that puzzles me is that a lot of people were saying that the software limits acceleration back when the quickest 0-60 mph was 3.07. Now, someone has gone 2.98 they are still saying the same thing but the goal posts have moved.Honestly it sounds like the plaid example isn’t particularly relevant to the question of whether a Model 3 deliberately limits acceleration (whether linear or angular) to a fixed amount regardless of weight.
It also doesn’t sound like anyone at this point is going to be convinced outside of their current beliefs.
Yes, I updated my wheels and tires in the configuration settings screen. I chose 18” wheels without Aero caps and summer tires. It doesn’t change anything for acceleration though.Did you change the wheel size in the configuration after changing over? I just put mine on
I tested this at the track. First two runs were with a 100 lb passenger. 0-60 mph times were within .01 seconds of each other. Same lane of the same track with everything else the same.Add 1 person and see what happens. There will be no difference in 0-60's
For sure. Was just curious if I needed to. I changed it to the sameYes, I updated my wheels and tires in the configuration settings screen. I chose 18” wheels without Aero caps and summer tires. It doesn’t change anything for acceleration though.
They won’t fit over the brakes, unfortunately. I am not sure if even 17s will fit.Just thinking out loud here (and sorry, I admittedly didn't read all 8 pages of this thread)... but how about slapping 15" wheels on a Model 3?
If the 18's are faster / more efficient than the 19's and 20's, I'd be game for 15's if it were possible. I'm less concerned with looks, and 15's would be cushier and less likely to experience curb rash.
Certain 17" might fit, I can check clearances. But honestly, I don't think there would be any benefit because there's not really many tire setups offered in 17" that aren't in 18" for the 3/Y.They won’t fit over the brakes, unfortunately. I am not sure if even 17s will fit.
What size tire did you try on the Plaid with the 18s?Certain 17" might fit, I can check clearances. But honestly, I don't think there would be any benefit because there's not really many tire setups offered in 17" that aren't in 18" for the 3/Y.
I was able to get an 18" wheel to fit a plaid OEM brake setup, but it's outside the certification parameters and am not going to do that.
Very few engineering challenges are linear and monotonic. The fact that (supposedly) 18's are "faster" and "more efficient" than 19/20's means that if you could just go to 15's that trend would continue is a very simple view.If the 18's are faster / more efficient than the 19's and 20's, I'd be game for 15's if it were possible.

I mean, brake rotors are about 13"- driving on those must be the most efficent, right?
I don’t think the acceleration benefit of 18s is linear. I think it depends on tire weight as much as wheel weight. After all the tires weigh almost the same as the wheels I have and ALL of the tires mass is outside of most of the wheels mass.Very few engineering challenges are linear and monotonic.

Remmeber that there is very little data here that it's just the wheel diameter that matters. Very few tests have been run using identical model tires in the same width and identical circumference.
