This snowmobile is reported to be about 98 hp.
In the trunk at the back of the sled.
According to what my Cat dealer informed me of, the 2010 TRV 1000 H2 EFI Arctic Cat has about 77hp. It can show that the TRV 700 H1 EFI is more aggressive from idle, that would be due to a shim to the clutch that Arctic Cat has installed to make the TRV 1000 a smoother ride. "Unshim" the clutch to deliver even more power out of your 1000 TRV.
Are the battery and charging system in good shape?
That would depend if you are asking about the 550 ATV or the 550 snowmobile. Stock HP (have no idea what you have done to "turn it up") 550 Pantera Snowmobile 80 hp 550 H1 EFI 4x4 ATV 39 hp
140-150 depends on aftermarket parts, miles, use, so on.
By the vehicle's nomenclature, it would seem so - "EFI" stands for "Electronic Fuel Injection", and usually implies a direct injection system (as opposed to indirect injection or common rail injection).
Actually, snowmobiles run on fuel so it's fuel power. Although they are working on it, they haven't made the snowmobile that runs on horses yet.
