i might be out of line for even saying but i just want to know. whats such a big deal about dyno numbers? they are nice don't get me wrong but if you are drag racing dyno numbers don't mean a thing. your e.t is what should be more important. you could have 400rwhp and if you are getting beat by the guys with 370-380rwhp that have the better suspension and all that stuff whats the use. now if you are just shooting for the 400 mark as a personal thing for yourself then thats what you go for its always good to have some sort of goal.
