I believe the VIs in the same grade are very close between the racing and street labelled oils.
Actually, the racing oils have the same additive pack as the longlife oils (BMW LL04, MB 220.51, etc). TBN is reported around 11, though Polaris is coming back in the mid 9's with virgin oil. Tons of detergents. It is designed to be an endurance oil. Kind of like 300V or Amsoil Dominator. Good news is the NT more than offsets the affects of the detergents, as far as friction. Wish we could make some without a high detergent pack for some of the professionals. Our gear oils are being tested in Mooresville right now, by whom I can't say but it would surprise folks. I'd love to get some low detergent NT stuff into their engines for testing.
Anyway, we may actually have some good news for you, specifically, in a few months. Can't elaborate.
Molekule, if you are ever down this way, let me know and I'll buy you a beer. I've not been back here in a while, was searching for a link that I posted a while back, but can't find it, and saw that this thread was 16 pages, and had been somewhat active, so I checked back.
