Kitcat,
Just to clarify, I'm not driving; not my car. The orange car from which the video was shot is a Stlaker with an L67 (supercfharged V6). I'm not sure of the HP. Before my own Stalker received its current LS6 powerplant, it had an L67 and made around 270hp at the crank.
The yellow car leading the pack is a Stalker with an LS3 (previously owned by John Meyer). This car, at the time, was making 530hp at the crank.
As for tires, I'm not sure what these guys were running in that day. HOTTTCAR on this forum could give you the specifics on the L67 Stalker as I think he built the car.
As for the other cars on the track, a handful were Birkins, one a Lotus Super Seven S4, and another a WMC Ultralite; not sure what else.
The video was shot during the Southwest Sevens Festival. To the best of my knowledge, it was a dedicated Seven event.
