How much boost does a stock 1100 make?

[Bkinz]

Anyone actually know what psi they make on 100%stock form?

Just curious

There is no right answer for that because they compensate for elevation. That is how Arctic Cat keeps them at 177HP from sea level to 10,000 feet.

For example at around 5000 feet they are running 15 to 16 psi stock, and at 8000 feet I think it was around 18 psi. This is a guesstimate because it has been a while since I have ridden a stocker.

Mine ran 15 psi at 3300 ft.

Around 18 above 8,000 feet.

Does anyone know the hp as it relates to boost eg 150 hp @15psi,200 hp@20psi ?

Are you asking if you stay at a set elevation and increase boost what hp it increases by? This would be somewhat dependant on the elevation. The higher you go the less headroom the stock turbo has. The stock turbo realistically can handle a constant 17-18lbs. If you are at an elevation that requires 10lbs to make rated power you could in theory add 60-65hp till the turbo runs out of the ability to compress air past 17-18lbs. If you are at an elevation that requires 15lbs, say 5000', you only have a couple pounds of potential boost left. This is why something like a BD 2.0 becomes less effective the higher you go. You can't get around the fact that the stock turbo physically can't produce more than 17-18lbs at elevation which is why something like the Evo mountain reflash uses the elevation maps in conjunction with timing to make more power with better fuel, and not go past the max useable boost number.

Otherwise boost lbs are irrelevant, stock or not, it makes whatever its rated power is all the time by controlling the boost electronically, until the max useable boost is reached then it just makes heat after that.
