i have only driven other racers rides w/ vspec and jx 21 , in doing so i realized that the p5xs in fact has more low end . not exactly "more" in every sense of the but different more
make sense
novarossi is a sort of guarantee you will get a great running engine that is easy to tune . the p5xs is "the engine" that i use in the truggy 95% of the time . just an all around killer engine , great performance value as it can be piped, clutched, plugged, geared to run so many different ways and responds well to all the changes . cant say that for some engines
i have been impressed w/ the jx engine but it is still not a novarossi
p5xs is better priced also
