Onsite Chargers For Track Days Tesla?

The problem is that you can't supercharge then go straight back on track and beat the car as the battery gets too hot from fast charging.
This is not accurate. The P has track mode, but even on a non-P, the car may limit max power somewhat but it won’t let you hurt the car or battery. You’ll be able to drive as fast as the car’s cooling capacity allows. b0rk said:

About 10miles if you head north on the A49, on the motorway junction.
Isn’t the instavolt in McD’s Winford nearer, 120kw so approx 80kw for a Tesla. About 6miles IRC.Ej1749 said:
I've heard Porsche owners say running as low as 26PSI (On Track) on the exact same tyre and size 20" as mine... and everyone else's I suppose.
What pressures do people recommend for track use on the Non-Tesla MP4S, lets say on a dry day at 15 degrees?
I have what everyone else has, apart from mine are the Non-Tesla Michelin PS4s (no obvious changes in road noise... Tbh, I didn't notice any difference), but for everyday driving. My on screen recommended pressure when I bought the car were cold 39psi rear and 41psi front. It has recently changed to 42psi front and rear.... any ideas why???
Does reducing down to 26psi sound a little excessive specifically for the track 235/35/20 Michelin P4S. I know that will heat up to about 30psi, but some have even said to heat them up and then re-drain them back to 26psi by doing a quick pit, to let the air out. I can see this making more sense on a lower profile tyre.
I wanna try it as standard as possible, the only variable being the tyre pressures. Then, come back with some track tyres that will fit 235/35/20, as I am limited with that size - and some uprated street/track pads .... Then, a 3rd time with non road legal pads or a big brake kit with metal brake lines etc, and maybe a suspension mod

26lb cold is to low for the car weight, it's just under 2Tons! Two things, with the tyre stretched on the rim in 235 size, its will roll onto the side wall in the
corners not good. Plus you would need to keep off the curbs, to prevent damage to tyre/rim.
I'd look to aim for 38lb hot on a dry day, I'm thinking of changing my tyres to a 255 or 265 width for road and track, to protect the rims from curbing and
stop them rolling onto the wall on track.
When I had my GT4 and CSL on track, Both much lighter car's. the hot tyre pressure was 30lb f&r.
I Fancy a silverstone this summer, are they their own chargers?

I’d start in the mid-30 PSI range and see how you like it. What pressures do people recommend for track use on the Non-Tesla MP4S, lets say on a dry day at 15 degrees?

Even on the P where you can leave the battery cooling on?
I hired the track prep m3p at the nurburgring. By the second lap (first was a slow one) half way through it was throttling power. After that I supercharged for 30 mins and left to cool for another 30 - about 1/4 way through third lap it had completely overheated and gave no power.
The garage was aware of this and refunded most of my laps that I paid for, they said the problem wouldn’t be adding extra cooling to the batteries but getting the software to recognise it as it automatically calculates what it thinks the temperatures should be - something a long those lines.
Edit: I should add that it was a Hot day
