hp guesses....

[yukon yamaha]

Every one here at the shop seem to have different ideas how much hp this sled will have, 2008 nytro w/
pc3, mpi muffler, and k&n intake, and a menztoy head light intake vent..... i am guessing maybe 140 +-2 hp
what is everyone else thinking....

Ive seen 5 hp swings posted from machine to machine...

if you have a good one yes..

if not could be around 135ish..

add a excell header and be much above those!

 

[yukon yamaha]

yes i think the excell header will be the next thing i get, i just need the funds now

Isn't stock around 138? With those mods he has to be in the upper 140,s. No???

Not going to disagree with your +/- and the Excel header with pipe.
The one thing I will add to the thread is clutching. If your HP isnt being put to the ground it really doesnt matter how much HP you have and even then the track is going to matter. So many things to consider along with the HP question.

absolutely...thats a given!

yes clutching will be todays game, i will be using all yamaha clutching and then a polar clutch and see which one works better....

yamaha clutching
8BU weights not sure what rivets
blue/brown/blue spring
and i think maybe a white/white/white in the secondary (maybe even a pink spring from epi)

as for the polar clutch well that is up to the tech, i don't know enough about the system to change things around

Mine made 146.3 at 9200 rpms with filters, plugs, Header, PC111 and an ignition module. the Best MPH I saw out of my stock was 102 the best I saw out of it modded was 113. When we added an after market muffler mine made 150 plus hp.


Here is a Dyno Sheet from dyno tech. the max HP made with a full system excel, filters, plugs, and a Pc111 was 147.8 on this particular sled.

Keep in mind every motor is different. But this is a base line.

Wow, The filters made power everywhere, especially down low. The headers really wake it up up top too. I would have expected the reverse from those two mods

 

[2008FxNytro]

guess i better order my filters and PCIII. Thanks for the info!!

Great info dirk, thanks! That is the exact setup i have on my sled. Always wondered what the dyno would read

Isnt that interesting..if any of you guys remember the recent debat with the cheap bolt on boost....you would lose the filters and add a restrictive plenum at least in the low to mids..telling!
