The C32 dragtimes data is interesting - but if you just look at just the quickest times, it's a bit of a crapshoot. 7 C32 timeslips are posted that are 12.5 or quicker - of those, 4 are 178's (2 are the same car/driver), and 3 are 185's (2 are the same car/driver)... they seem to alternate back and forth a bit, and the non-nitrous runs all have very similar traps (109-110). Seems to lend at least a bit of credence to the hypothesis that much of the added boost of the 185 setup is negated by it's incremental heat production.

Agree with the sentiments above that 185's are likely to be torquey street monsters, assuming appropriate cooling upgrades have been addressed. That said, 178's appear to be better suited to higher rpm situations.
