Title: adding power to '03 f-7 actic cat with 153 track

 :banghead:

hi I'm looking to add power when I'm out west in yellowstone. I do very little riding while at home in MN. I seem to run out of power and speed during long climbs. I'm reving to a max of 7500rpm with 62 weigths and stock spring, along with recommended gear changes. I nervous about adding NOS but not adverse to it if safe. I have added a d/d pipe and can. but am a little disapointed I am unable to get over certain obsticles. I don't want to go out and buy a newer bigger sled. just add a couple surprises for one of my friends... :devilsmiley:


does anyone have some good information for me for a safe boost of power.

thanks, roy

I'd ask the question on Arctic Chat or HCS...or call Speedwerx or the aftermarket shops directly. There's a lot you can do to that motor if you want.

The power is there assuming there's nothing wrong with the sled.  Just find the right guy to twist the wrench.  This is my motto

I'd be looking at under hood temperature's and I would also check to see if your clutches are getting hot.  Don't use your tongue :biggrin: Touch the clutch surfaces very fast to see how hot they are and inspect for belt material left on the clutches.  Check your shift-out too.

Also tach's are wrong more than right in my experience.  Does it sound like 7500?  Tough question to answer sometimes.  7500 is going to sound VERY doggy.
