Couple of SCCA SM racer friends I sent the video to commented on how NASA SM is known for "inventive" car/engine prep and suspected that the guy's SM may have been somewhat "juiced up". They both pointed out his >7500rpm shifts shown on the video whereas the SM rev limit should be at 6950.
Good point. I've heard that the likelihood of a teardown is low at the regional NASA and SCCA races. The stakes get higher at the SCCA Majors, and at either of the org's championships. At the NASA championship last year the winning SM driver was disqualified for an illegal modification to the CV joint cage. At the SCCA Run-offs at Laguna Seca in 2014 (IIRC), something like 7 cars were DQ'd for illegal head modifications. But at the local level these kinds of tear-downs are unlikely, and inspections usually don't extend beyond simple compression ratio tests, maybe a dyno run, unless another competitor files a protest and puts up money to pay for it.
