Brad is at 6,000 and above...and your HP isnt going to drop but maybe 10-20hp depending on supporting mods.
You are delusional.
Quite seriously... you need to read up on how altitude affects horsepower.
I live here, I'm not dancing with some theoretical hopes & dreams, I deal with it DAILY, from sleds to cars to trucks, jeeps...
Nobody claims HP at their altitude, as that would be a disrespect to their product, since everyone else uses standard corrected numbers,
BUT...
Let's say he did, just for fun, cause I like fun stuff.
So, at the top of the climb about 8 miles from my house, you'd then be at 175 hp... which is what a PUMP GAS turbo dyno'd at, at elevation, 5 years ago. And I know Wyo isn't going to put in a PG setup, neither would I.
Add a head, or whatever mods you think would get you to that "only 10-20 HP down" and you'll gain maybe 10-15 hp of that back... MAYBE.
but, since that was just for fun... the reality puts you back at less than 160 hp, max up at my altitude.
There's a reason so many of us ride boosted machines around here... they just make up for what we lose otherwise. You still lose some with boost compared to down low... but not even in the same realm as N/A.
