hi all

just had my raptor on a dyno.jetting and airbox mods gave me allmost 3 hp extra.
take a look at the chart at http://expage.com/660r
ps--- i am at 5000 ft

The corrected HP is is just over what they are saying the stock Rapotor dynos at. Do you have any more details as to this and why?

 

in stock form at 5000 ft the raptor pushes 32.5 hp
there is a lot of people that talk a lot off sh*t.
i did the run on the dyno myself and i changed the jets and drilled the airbox lid .add 15% for sea level. 43.7 hp
the test is done in 4th gear from 3000 to 7500 rpm
ps-- it is rear wheel hp

according to your expage site all i saw was 39 hp.where did you get 43.7? i dont see how you can add over 5hp just by drilling holes and rejetting.i could be wrong,it wouldnt be the first time thats for sure.

 

the 38 hp is at 5000 ft. you add 15 % for sea level , that is where most pipe builders do their tests.

Hey Bash that sounds like alot less than CT was claiming, have you found out anymore on that?

 

Nope, I just thought I'd wait for someone to buy it and see what difference that there really is.

 

I think that CT was for the ENTIRE pipe, not just a slip-on. I heard that Yamaha f***ed up the header piped. Very restrictive at the 2 into 1 point.
