hp gain with after market engine parts?

[alaskin 450R]

i was just wondering but how much horse power does my 400ex have. i no that stock it is around 27hp, but i have a hot cam stage 2, dyno jet kit, pro curcuit T-4 slip on, and a whitebrothers rev box and its also geard down? what do you think my horse power would be?

im GUESSING about 39hp??? maybe im wrong but thats what i think

39 horse is way to high:p , i'm gonna have to say its probably only putting around 29-30 horses at the rear wheels.
