i decided to write a program from scratch using visual basic and this is what i came up with.
the program is a horsepower and torque calulator. all of it is estimation based upon forumlas, so its not to be mistaken for a dyno run (obviously) but its pretty nifty to mess with.
the torque is most accurate if you enter 4500 as the engine rpm...
