It could be tweaked Raven. May be they sell that as a track version of S - for $150kBecause to my knowledge the Raven still can't do track laps without throttling. Am I mistaken?

There’s zero chance he would announce this in advance, let alone IMMEDIATELY after the Taycan spec reveal, if he didnt already know for certain it could make it all the way around without throttling, and beat the Taycan’s time. IMO this implies something more than a mere Raven Model S.
I don't believe that is true of this one. 2 350kw CCS plugs IIRC. Ill have to take a trip and check again tho. It looked like this one:There is always one 50kW CHAdeMO plug at an EA site. (Shared with a CCS plug.)
When have you seen a Raven tested on a track like that?Because to my knowledge the Raven still can't do track laps without throttling. Am I mistaken?

The Raven probably has an upgraded cooling system. And as long as throttling is not significant it should be and issue.
Ooh I’m loving this:
Tesla Haters: “Yeah, but it’s a crappy track car.”
(Tesla beats Porsche at the track).
Tesla Haters: “ummm....fake news?”
Model 3 SRPMs are cheap now that they're in mass production. They've already installed one in the front drive unit of the Raven. The engineering for a dual drive rear powertrain was largely complete after the Roadster 2 effort.Why are people speculating about a new S variant? It's not effective marketing for the S if it's something you can't buy. Rather, it'd be osbourning the S if it's something that's not out yet.

This is actually a good question.
Raven might not have been tested yet, and actually does significantly better than past S variants.
New software update that improves track cooling?
With the new switched reluctance (front I believe?) permanent magnet motor on the newer S’s, there is less heat generated. So they’ve probably figured out how to balance the torque to minimize the heat and eliminate the cooling problems of the past. Raven probably has improved cooling?
And there MIGHT be a new hardware variant they’ll unveil, although I give this the lowest chance of being the case.
Primary propulsion is from the PM motor, which doesn't overheat. The induction motor provides supplemental power; it gets throttled back first. Even on the track, the pedal isn't flat down nonstop. In the old S/X config, there was no point in time when the induction motors weren't working, but in the new arrangement, they get significant "time off" for cooling on corners, chicanes, etc.
At least, that's been my take as to how it plays out in practice. There might also be other factors at play.
That's not the problem with the S/X AC induction motors. The problem is WHERE the heat is created: in an AC motor, heat builds up in the copper windings in the internal rotor, where it can't be actively cooled, just aircooled as it spins in already heated air. The resulting heat-soaking is the reason for the power roll-back with S/X hard usage.With the new switched reluctance (front I believe?) permanent magnet motor on the newer S’s, there is less heat generated.

In contrast, the SRPM motor has its winding on the outside stator, where they can easily be cooled (Model 3 uses a chiller plate with coolant circulating through it; there's a Youtube video by @Ingineer if you haven't seen it yet). The SRPM internal rotor is just a piece of steel with no windings, and so doesn't build up heat.
