Efforts to equalize blown and NA engines in the same class have been pretty much a losing proposition ever since the Duesenbergs first ran at Indy in the '20s. In the case of an SCCA National class, where people pretty much make decisions about "competitiveness" from just one race each year, this will never be adequately resolved.

But at the end of the day, the dumbest thing that i can imagine doing in this situation would be going 4 seconds faster than the competition...
