I had this question brought up to me this weekend about the Sno pro cam. I was asked if there was a difference between the sno pro cam and the F120 camshaft. I was told that the F120 had the sno pro camshaft in it. Is this true? :sos:
I'm pretty sure that is true. The SnoPro was introduced in 2001 I believe. You could buy that cam in the upgrade kit for the 2000-2002. In 2003, they went ahead and put that upgraded cam in all the motors to date.
The cams are different. The 2001 Sno Pro cam is part number 0691-922 while all cams from 2002 to current are 0961-914. The 2000 and 2001 standard 120s also have the "sno pro" cam, but that's not what they were called when in production. It's only been coined "sno pro" since the 2001 sno pro 120 was built.
I've also verified this directly through Arctic Cat. That's also why ISR has it specifically mentioned in the rules that you can swap cams to the Sno Pro cam. The rule wouldn't make sense if all the 120s already had sno pro cams.
Bottom line: If you have a 2000 or 2001 120, don't waste your money on the "sno pro cam" since you already have it. If you have a 2002 or later and racing in stock or improved stock, then you'll see a performance gain.
I guess I had it wrong all this time. I remember Scott at Recmotor telling me a long time ago that the 2000 and 2001 had a standard cam. They made an actual SnoPro model with SnoPro stickers on the side of the sled in 2001 (thought it was 2002 too but I guess I'm wrong about that also). The 2001 SnoPro had the better SnoPro cam and was the same as the upgrade cam kit for the 2000-1. I was going to buy the kit but Scott said my son's 2003 would not benefit from the SnoPro cam because my cam was basically the same. You learn something new everyday.
At least I know where that rumor came from now. I've had several people ask me this same question this year and I didn't know where they were getting their information from. And unless my 25 year source at the Arctic Cat factory has his information wrong.... and the part numbers are messed up, this information is correct.
And thank you very much for giving me the background on this.
