Personally, I find the whole situation ironically amusing. Kinda the same as when I drove a '71 VW Beetle with a turbocharged 914 engine in it. If someone driving a musclecar beats a Miata / Beetle in a stoplight drag, they're going to sound a tad silly bragging to their friends about it. On the other hand, if they are soundly beaten by a sleeper Miata / Beetle, well, you pretty much have to commit suicide at that point.
I just love it when, after said exhibition, the driver pulls back up next to me and asks "what kind of engine do you have in that car?" (presumably expecting it to be sporting an LS1 conversion) to which I always reply "1.6 liter," omitting any mention of running it at 15 PSI. Or (from the ricer crowd, generally) "You got nawz in that thing?" which gets answered with a simple "No."
