Just wondering what the top speed of a brand new ( broke in) 2010 800 summit is with a 154 inch? Today my dad and I raced several times from a stopped position and I can kick his @ss with my 700 summit with brand new short block. I mean right off the start he gets maybe a 2 sled length lead but at around 60 km/h I blow right by him like it is rediculous. He is topping out at 65 miles per hour, and my spedo reads just under 120 km/h.... He is pissed off and calling in about it tommorow. Any ideas? And yes I know they are geared for the mountains and stuff but still....
