Can we have this for quarter mile drag racing only?

Post up your time slips, videos, and let us know any modifications you have on your Model 3. I would like to see the data from everyone's Model 3. Let us know what cars you take down or who beats you. Include track conditions, temperature, state of charge, etc

I'll start. This is my second Model 3. My first was a 22 LR and now I have a 23 Performance.
I have not had my Performance at a real drag strip yet but I have used my Dragy.
I'm completely stock. Less than 1000 miles on the odometer.
Temp was in the upper 40s Fahrenheit.
State of Charge was about 60 %

This pass was nothing special. Seems slow for a Performance. I'm guessing SOC was too low. I'll go again ASAP.

It is a bit hard to see, but follow the charts to see how much power you were losing with a ~10-15 degree battery and 60% SOC, compared to 95% at 40 degrees after a fresh Supercharge!

 

[sike-o]

I charged all the way to 100 % and by the time I made it to Mexico I was at 96 %. These numbers are a bit better than my original attempt.

I have been playing with my Dragy (first time today). Best 0-60 of 3.37 (3.15) at 90% SOC and 38C battery temp after preconditioning at home and then using the S3XY Battery Preconditioning function to get it from ~20C to the ~38C.

Given the results see from stripping ~200lb out I have to say I am more intrigued by weight reduction…

You will need to get the "Battery Mid" temp up to about 52 degrees C to get optimal performance. Try the "Navigate to a Supercharger" trick first. Then if it doesn't get to 49+ degrees C use the S3XY buttons preconditioning to see if you can get it higher. You really need to be seated in the car with your foot on the brake and the car not plugged into any charger for preconditioning to work fully. You can also precondition while driving but that is going to use a lot of battery. If you get out preconditioning sometimes stops.

Turn on "Beta" data in the S3XY buttons and track your "Max Discharge" value. You want to see 458 KW or more before you launch. However, that value mostly affects acceleration above 40 mph so it won't affect 0-60 mph as much.

Weight reduction is key as well. Change to 18" lightweight wheels and it will absolutely help. The best thing is weight reduction with a full and temperature optimized battery.

2022 Model 3 Performance with 10k+ miles on it. 8.5x18 T Sportline TS5 wheels and 235/45/18 Michelin PS4S tires. Front passenger seat, rear seat bottom, rear seat uprights, and Frunk all removed. Car weighed 4,110 lbs with me(190 lbs) in it and 3,920 lbs without me in it. 44 PSI in all four tires.

Perfect prep on the Dragstrip but cold 48 degree F temps(-498 DA). 100% SOC with 48.5 C “Temp Mid” and 458 KW “Max Discharge”.

11.17 @ 122.93 mph according to the track time slip and 11.17 @ 120.0 mph according to Dragy. This was with the old DRG69 Dragy. I have the new DRG70 Dragy now.

Here is a video of some of my best runs this summer.

Yeah, I actually got most of that from your YouTube video! I was indeed using the S3XY Beta page to see the 38C battery Mid temp, and seeing something like 448kw max discharge if I remember correctly. Unfortunately, I was only doing a few quick pulls during the long way to work, so I just started at 95% SOC from my garage and was down to about 90%, mostly from preconditioning, by this run!

Also, unfortunately, I am way too far from a Supercharger to activate preconditioning anywhere near my daily operating area. I have, however, seen 45+ mid temps from preconditioning after maybe 15 mins (with 20C ambient temps), with no indication it had peaked.

Today I got several 0-60 3.3s (3.14, 3.15, and 3.16) at 86-90% and 40-45C Battery Mid Temps, which seems about right. This was with my Dragy69.

It took 10 minutes of driving and another 15 minutes sitting in Drive with my foot on the brake to get this much heat into the battery, starting at 20C. (My battery reached 20C by the time it hit 98% and I had to leave). I used 6% battery to generate this much heat (plus driving about 8 miles).

Not going to lie, I am getting more and more tempted to lean into weight reduction…

If you really want to optimize it then charge to 100%, heat the battery fully, then charge back to 100%. That is what I do at the track. It really helps to do it when it is warm or after supercharging.

Heating the battery can draw as much as 11 KW. That drains the battery really fast but the heat really does help on the top end as you get close to ~458 KW Max Discharge.

Weight reduction is easier but both together really are the key.

If you want help removing seats I can walk you through it. It is actually easy once you have done it a few times and if you don’t have the seat covers I have.

Funny, they make those oil pan heaters for cold climates. A little pad you stick on to the oil pan and plug in to a 110 outlet to heat your oil to like 120F. I wonder if I could place a couple on the battery and pre-heat for a few hours to more than 20C in my garage .

Though, really, I will probably start with some lighter wheels and tires. I think I can drop another ~10lb per corner with some lighter 18x8.5s and 235s, which would be about like dropping another ~70lb total from the vehicle.

Then if I decide to go racing I could pull the passenger and rear seats, frunk lining, etc, bringing the total to perhaps 225lb lower than stock.

Beyond that, it is thousands in trunk / front CF, door and roof lexan, etc, to save another perhaps 75lb. I could also do an UP racing seat on the drivers side to save another 35-40lb. So… that last 100+ lb to shoot for a 10.99 is a good $10k .

How many other people have actually achieved a 120+ trap speed (without significant weight reduction)?

As far as I can tell no one else has even done 119 mph in the 1/4 mile on Dragy. People have done it with track time slips but those are rarely accurate for trap speed.

Races have been won and lost due to reaction time. Under .2 is great. For the weekend racer shoot for under .3.

Former motorcycle drag racer here. Kawasaki 900 Ninja. C/S in the now defunct IDBA. Interesting that a M3 is close in performance to my drag bike. 11.teens at very low 120s.

120s on a bike must feel like light speed compared to in an EV.

Oh yeah. At night the lights going by kinda reminds you of the Enterprise going to warp. It's nothing compared to the Top Fuel drag bike record set by Larry (Spiderman) McBride. 5.618 @ 268.38. Photo of the timing slip can be seen here. Check out those reaction times.
