the 93/5 have the edge on top speed but many of the early 90 cars are a bit lighter and ran some fast 1/4 mile times.

general concensus is that the light weight of the 90's were the quickest, 93/5 the fastest. either way, the 30 HP didn't make as much of a difference as you would think!! cars also varied in performance quite a bit, which is odd considering the uniform manufacturing techniques.
