Power?
I think everyone has their own opinion on hp with boost. No doubt that you need to have respect for the #'s but to be afraid of it is a little off base. The power is linear and does come on very quick(that's what it's supposed to do right)but you have control over the time you hold the throttle open and how much you open it in the first place. You also get use to it just like the first ride on an 800 vs the 500 you traded in, it just takes a little time.
I know of one '09 PL Nytro for sale in the Sicamous area and I know the owner of that one is NOT afraid of the power.
These sleds clutch out fully and reach about 100-105 if the belt is good.With stock gearing it really does not go much faster than a stock sled, it just gets there really quickly
What does a Low Boost kit cost, complete and installed? What is max-safe boost level on 91oct?
I know that not everyone is interested in big hp on the Nytro and that some just want a bit more punch but I don't think 280hp is something to be frightened of unless you gear it up to run 200mph on a lake or something. If you know 180-200 is all you will ever want then the low boost is likely the way to go but if you ever think you may want a crack at more hp then do it the first time cause the hit your gonna take on the cost of the build at resale time is huge either way.
So there you go, now you have one more opinion.... for what it's worth. Good luck no matter what you do and I'm sure you'll enjoy it either way.
