Desk top dyno 2000,any body ever"check" with real dyno pull after building engine?

YES... I have used Desktop DYNO 2000... I built my motor about 2 years ago, and then after it was in and running I got DD 2000... (last Christmas no less...) a little bit late at that point, but I wanted to check my #'s anyways... so I played with it for a while and then plugged in ALL my specs... DD 2000 said I should be making about 330 HP at the fly and when I had it dyno tested this summer I made 267 RWHP... if you consider the 18% loss through the drivetrain I make about 320 flywheel HP... that means with my application DD 2000 was only off by about a 3%... so it worked for me, but we will see... I am almost done putting together my brothers 350 and DD 2000 says he should make about 375 HP at the fly... but it will be a while before I can have that Dyno Tested... just remeber that computer simulation like DD 2000 assumes IDEAL conditions for a lot of things...
