ALWAYS IN LUDICROUS MODE! P90D>P100D Upgrade
No drag strip yet... just over 200 miles on it so far
Ill have to look into one thats closest to a charger!!

Newer P90DL makes 662 hp at the battery!!!

Ill have to look into one thats closest to a charger!!Elon said 90% had the lowest IR. But that doesn't mean 90% generates the most power. The lowest IR just means there's the least amount of voltage drop, but your non loaded voltage is lower at 90% than at 100% so it's possible and even likely that the extra voltage at 100% overcomes the slightly higher voltage drop due to slightly higher IR.
No, because Tech_Guy still got 507KW at 92% which is WAY more (68 hp more) than my 456KW at 91% with max battery ready.
1/2 Megawatt will be enough to get a solid 10.9 second run. I have no doubts at all about that.
I'm also willing to bet that MT had an early version of what is now the current higher power P90DL.
If I were a P90DL owner with the older 456KW car, I'd be hoping mad right now. When these newer P90DLs start pulling down solid 10.9s, are you guys with early P90Ds producing 70 hp going to ask Tesla to make it right by upgrading whatever hardware needs to be updated to produce a 10.9 second 1/4 mile?

It's great that you are willing to test this so early in the car's life!
Going to be very interesting to see if these figures hold up after a few thousand miles. Most of the degradation on lithium-ion occurs during the initial charge cycles. I have been wondering if Motortrend got a brand new battery in their test car. Perhaps a 10.9 is possible on the first charge but after a couple of charges you start to see declining figures.
Auto Club Dragway in Fontana is 5 miles from the Rancho Cucamango Supercharger but they have a limited schedule for street drags. The next one is July 24th. Irwindale has 1/8 mile drags every Thursday between 5 and 8 and the cost is only $20 to drag and $10 to watch. I will be there June 20th. There is an Edison free charge point 4 miles from the tract but that takes a long time to charge so I charge first in Burbank to 100%.No drag strip yet... just over 200 miles on it so far
Can you find a drag strip that just has a public charger near it? It doesn't have to be a supercharger. How about a strip that has a 30 or 40 amp RV hookup? Or a dragstrip next to an RV park?
You could also haul one of these along:
Amazon.com: DuroMax XP10000EH, 8000 Running Watts/10000 Starting Watts, Dual Fuel Powered Portable Generator: Patio, Lawn & Garden
Continous output of 8KW, but the 30 amp 240 volt plug should get you 7.2 KW which should be good for about 15 MPH. You could stay 100% charged for all passes you run. Killer on the battery life especially baking it at Max Battery temperature, but you'd probably get multiple solid 10.9 / 122 MPH slips.

14 KW is more than a couple and certainly not a statistical error. I'm a data nut and have collected dozens of runs during the last 6 months. 453 KW has always been the max and that was achieved with and without Max Batt Pwr. I've also kept track of posts in the TMC of max power recorded and never saw anyone post above 456. Sorry that I missed yours, especially the 470. What software version were you running?
Anyway, I feel that there has been improvement in my car's performance associated with the Max Batt Pwr mode after the recent software upgrade even though it is much smaller than the refreshed P90Ds. I'm still interested in seeing the KW for 90% from a refreshed P90D with Max Bat Pwr OFF. So far, the only post close to that is Tech_Guy's refreshed 457KW at 89% for Max Bat Pwr OFF.
I just tried this method and got 452KW at a 95% SOC.
With about 1.5 hrs left to 100%, I turned max battery on and in about 20mins it was ready.
I charged to 96%, had some difficulty connecting, and then at 95% still with Max Batt ready, got the 452KW.
I might try a higher SOC, but I don't know how much if any improvement would be forthcoming.
I'm running 2.20.30 and my car is a P85D with Ludicrous.

You cannot, but you can report your post (bottom left of the post) and describe in the field that you would want to change the title. A moderator changes the title then if (s)he finds it reasonable.
I would not be happy right now if I owned a P90D which was putting down the same power as a P85D right now.
I'd want some answers.
From the looks of it, Max Battery seems to be offering significant benefit over the mid 450KW range for late model P90Ds with Ludicrous. A 10%-12% increase.
But at this point seems to offer less of a benefit for some of the older P90D Ludicrous cars as the one gentleman only saw an improvement of 14KW at 97% SOC over his prior bests.
It will be interesting to find out why.
Also, I'm going to do another log at 100% and Max Batt and see what it shows, but there has probably not been much if any improvement in the retrofitted P85Ds.

I charge to 90 nightly, ill take a reading tomorrow for you at 90% on Ludicrous without Max Battery Power.
I know you're kidding when you say "lowly 454kW P85DL"
But consider;
fiksgts has run 11.2 at that power level
real world all models 0-60 times and 1/4 mile times
And one other P85DL has run 11.2 as well.
And of the other recorded 11.2s, and at least one of the 11.1s, it's unknown to this point whether they were making any more power than your 454kW.
If I don't see 500KW, then I'm satisfied with that kind of performance capability.
But who knows? For a long time Max Battery really didn't do much. Perhaps now it will actually do more than what it did previously for all cars with the option to select it.

Thanks! You might want to charge it to a few percent over 90 right before going out so that the battery is at a good temp and you have enough charge to get where you want to test at 90%with Max Batt Setting OFF. Very much appreciate your efforts.
