Polaris RkTek 858 vs. Polaris Boondocker turbo

Quick drag between my RkTek 858 big bore, and a Boondocker turbo sled on 7psi. Both run straight pump gas. Big bore in the right lane, turbo in the left.
Not bad taking into consideration im still breaking in the kit, and missing 200rpms because my clutching isnt right yet.

Which snowmobile had the length at the end, the rk tek big bore?
