177 in the 1/2 mile at 7 psi sounds doable. 193, not so much. Not saying it can't be done on race fuel if you jack the boost up high enough, but if it's being done on a stock engine, and especially a stock tranny, it isn't going to last very long. Would be interested in more details on the car that did 193--fuel, boost, and whether the tranny was unmodified as well, etc.
