Just speculation here, but I bet the F.I. version of our bike would easily pump out over 30 HP once a Power Commander (or similar) is released, if combined with a pipe and a big bore. But for us poor shmucks that bought the '09 with the carburetor I think 30 is about peak for a reasonable build.
Just my .02, as I said before, I'm a psychology major not a mechanical engineer.

While I agree with the point in general, what's with the math. The bike dynos at less than 18hp completely stock. Dirt Bike TV dynoed theirs at 17, so it's more like an 8 to 9hp gain over stock.
I know, EMS, it's easier to make a point if you water down the figure, right
You get 6hp alone from the 250 to 331cc increase.

And on the production Impala:
The car you see on the track Sunday has absolutely nothing in common with the car you see on the dealer's lot. It is a Chevy by name only, just as if you gave NASA your 249cc Kawasaki engine and they gutted it to the core, replacing every piece with their custom-made parts. No longer a Kawasaki.
