New Carb Big Bore Horsepower ratings from C.A.R.B.

Here are the current HP ratings for the Big Bores. The info is from 2008-2009 certifications in CA.
These numbers are measured at the crank, not the rear wheels. If you would put your machine on a dyno, you would get a lower number due to losses from the tranny setup. Rhino numbers are the same as Grizzly, Brute are the same as the Teryx.

Good info Marty

Interesting stuff. Note how the Brute 750 Carb has more HP than the Brute 750 EFI motor.

Not according to the carb stuff i read on the new teryx, efi listed at .4 more. I think these specs are for atv's, the sxs motors are set up different in the way they are tuned. So they could have different readings.

Also i think the EFI's are very limited in there stock form.
once the ignition and fuel map is changed the EFI's make extream
increases over the carbs.....

I have rode both carb and fuel injected teryx and i can tell you there is no comparison
