what color plastic does it have? red gives you 5 more horse
and if you have a sticker kit your looking at atleast 100hp to the rear wheels!:eek2:

Just get the purple powerband, easy 65 HP with stock pipe, don't listen to these guys, you can't get 80+out of the engines :rolleyes:

Just so you know though, with the purple powerband the reed valves tend to wear out faster.

forget about the purple powerband, get the flux capacitor, but you WILL have to get carbon fiber intake valves to handle the plutonium at 88mph. This should get 120hp to the rear wheels, i know mine is putting abt 110hp when i did a dyno run last night, but i havnt put on the k&n sticker yet

i have a few 450r that i have had on a dyno jet dyno 250 a stock 04 05 450r is around 34-36 on this dyno and i have a 450r with about the same mods and the head has had a little clean up on it from the local shop and it made 47.6 and like i said it has cam piston and pipe filter and the head work so 42-45 is going to be close on this dyno

yes this is what i figured 40-45 at wheels which is good and most people dont know that.. but you always have to remember that i'd say 90% of dyno's are different.. i have seen it with streetbike, one dyno to another can be up to 10hp different. i have even seen some guys use them wrong.. you have to use a 1 to 1 gear ratio to get the true reading, the main purpose for a dyno is to use the same one and as you make changes you can see your gains along the way..
