Tesla Model 3 - Making Power With Heat!
Вставка
- Опубліковано 17 жов 2024
- It's time for another MPP Tesla Dyno Test! Today we are testing to see what battery temperature is going to make the maximum amount of power from a Tesla Model 3 Performance. This will be very important for the drag racers out there who are looking to get the most out of the car. We also found that there may be some software limitations, but you can be the judge. Let us know what you think in the comments below - we are also open to more testing ideas!

Sasha: hmmmm 479.
MPP... where dyno pulls meet The Price Is Right :)
Thanks so much guys for yet another fascinating and informative trip into my car's brain!
good work, sasha! any plans to summarize all tests and charts into a single document? would be great even with a giant mountain pass performance watermark...
I wish you would add heating as an option in your party module as some of the tracks I drag race at aren't close enough to a supercharger to activate the heating 😭 please consider it help a brother out
Thanks for doing this Sasha. I can confirm that when the battery is hotter my elapsed times are quicker in eighth mile and quarter mile drag racing. And sometimes it's quicker for no apparent reason. :-\ typically only by a few hundredths.
I raced last night and supercharged before the event with preheat. The car ran it's fastest pass ever at 11.496 on the first of 6 passes. By the time I got to the finals some 4 hours later, it was running around an 11.60. The ambient temperature dropped around 30° during that time. Highlight of the evening... in the semifinals, I had a .013 light and went dead on with a 7 for a 20 pack. :-)
So fun!!! That's awesome to hear :)
@@otarpilot292 Did you try navigating to supercharger to preheat battery during finals?
I like my Ingenext Ghost mod because it let's you force the battery pre-heating on or off. :)
Nice dyno test!! Can you dyno test q2/21 sr+ LFP 55Kwh. It has perf rear motor to compensate the weight. Nice to drive when pack is warm.
Great work! We have found the best performance at the drag strip to be a hot battery!
Good info, thank you
Hi Sasha. It was really nice to finally meet you in person! Keep up the great work!!!! See you soon...
Is this a pre 2021 refresh car? It looks like it from the piano gloss center console. If it's a refresh car, it would be useful to know what the battery model it, with all of the variations now on the market, and with the refresh ones performing poorly in sub-zero temperatures.
If the M3P is making 487WHP what does that convert over to from the motors? What percentage do electric vehicles lose?
The battery is producing 408kW or so - which is 543 horsepower. There is approximately a 4-5% loss in the battery, 6-8% loss in the inverter and motor, and the rest in the drivetrain. From that you can conclude that our dyno is reading a little bit too high in reality, as the losses shown by our dyno are not large enough to be realistic.
I think ridiculous launch mode will be coming. The movie reference that plaid and ludicrous come from also has a ridiculous mode that slots below ludicrous and plaid. Would make sense for the 3 which at this point does not have a launch mode with preheating.
it's ok to peddle your products when you really believe in them.. Super interesting to see what the approach to tuning these is! Looking at how electric cars perform through their rpm range, it really seems like they would benefit from a gearbox? Surely they have a kind of opposite approach to gearing than internal combustion, high rpm for efficient cruising and low rpm for max power?
So what I've learned from this is I need to get a Motec. 😜 Great information guys. I'm curious how much this effects lap times around BRP.
Your can see this with scan my tesla and the obd2 adapter as well. You can use an old iPad or tablet too
We'll have to see if the power output truly is the same above 35C, in which case it wouldn't have any affect at all. You would already be above 35C by the end of your out lap!
Otherwise you can figure very roughly about ~1-2 tenths for every 10 horsepower.
A test right up my alley :) There's a Temp Percentage signal...power might climb till you hit 100%. Time for a bigger dyno?
How were you bringing battery up in temp? Pretending to drive to supercharger?
Exactly! It works up to 45*C.
Are you running a motec ecu?
Are you guys looking to other EVs too now? Polestar 2 for example, Porsche Taycan, quite a few EVs with plenty of track potential now
Is it possible to have one torque/horspower chart that goes up to 14,000 r.p.m. with the different overlays of battery temperature pulls. The chart you used was hard to understand.
Hi Sacha I wonder if you had a spool or a limited slip diff in the rear power train would the dyno result be more stable ?
Yes it would be for sure.
So battery temps play a huge roll into the over HP. Does the SOC effect that as well ?
Sure does, see our other video about that!
More graphs! More charts! :)
Hey Sasha my friend how you doing good job man keep it up and R&D also
for model 3 dual motor PERFORMANCE 2020 can your dongle or module can boost my tesla inverters by adding 50 or 80 hp OR more ??
I'll pay $1,500 dollars for that module that I can easy take it off and easy and fast plug it in an any time ??
OR even better can you add to your module some kind of switch that way I can power off or power on on demand and that switch will be locate somewhere around my steering wheel will be awesome to have that magic switch or button I would call that E-NOS on demand
PLEASE Let me know !!!
I got 2020 P3D
Very cool 😎
Moar powa!!!
I'd love to see a test where battery temperature is held constant and motor temperature is varied.
What torque numbers were you seeing at the wheels?
just about the limit of the dyno - around 3500Nm at the rear axles, and 2000Nm at the front axles.
Is there a golden ratio of whp compared to bhp?
12-18percent from engine to wheel loss depending on the transmission. For an electric car this loss is much less but I don't know the exact figure.
I know the answer but I want to know what you guys think between buying a P85D or M3P?
M3P from an owner.
Depends what you do with it. I wanted a car I could take on the road course that felt more nimble so I went with the m3p. If just a daily driver and some drag racing the model s has more room but the p85 is slower than model 3 performance unless you go to a p100d
Looks like u need a new dyno 😂 or Tesla needs to let you uncork it 🤙🏼
1000HP GTR, no problem. Model 3? OVERLOADED!
@@MountainPassPerformance new torque monster
The music is a smidge too loud.
