how much hp??

[WB450r]

i jus got my 05 450r motor rebuilt as part of this winters rebuild..
how much hp u think i got out of this

13:1 cp piston
stage 2 hotcam
port and polish head
dasa full exhaust

also got a couple things updated

crank and bearings
intake and exhaust valves
exhaust guides
cam chain
etc

id say around 50 i dont know much about how much these motors are supposed to make with those mods though.

I would say 85HP to the rear wheel. and if you pump up the comp of the piston it will add 10 more. Also make sure your head is polished so you can see yourself in it.

Ha. Roostar 450, I actually thought you were serious till the last part.

45 to the rear wheels on our dyno is what most 05 motors with those mods produce. You would see around 50 hp on a dyno jet dyno

i was hoping to get around 50 hp

Why is everybody so hooked on dyno figures?I guess maybe it feels better knowing you have 50hp regardless of the fact most locals have their tongues on the crossbar pad after 2 laps on a mx track.But hey you got 50hp....:D

agreed suspension frist any day i'm not saying your dumb for your selection of motor mods they are very nice but dont be worried about havin 50 Hp dosnt really matter if you work hard on being a better rider. most of the times when I got beat i would of got beat if I had 70 Hp

I agree. Horsepower is just a number to me. My quad was recently rated at 42 hp. Its almost stock, 12.5:1 piston, Dasa, filter, but it feels like a lot more than that. I could hardly tell a difference between it and my friends TTM motor on his yfz-r

i already have suspension im not worried about that..i was simply asking a question and looking for a reasonable answer without a smarta** remark..

it seems every thread on here always has somebody being a smarta**

I'm not trying to be a smart ***** just giving an honest opinion. Plus your not going to get a reasonable answer anyways to many variables. you can take your exact motor set up and run it on 3 different dyno's and get 3 different answers what's size tires you run how much air pressure can make huge difference on a dyno and countless other things. dyno's are only really reasonable when some one is doing several different engine combos form a stock motor basline run and comparing the gains not the overall HP.
