Putting together what we are hoping will be the ultimate tree hugger! 13 Pro RMK chassis, 2008 nytro motor with 1900 miles on it. Going to try the tunnel dump exhaust, and doing a air box mod that would locate it in front of sled in nose piece. Going naturally aspirated, shooting for 465-485lbs and 150hp! Here are a few pics of the dry fit and small issues we have found so far.
