Jan 22, 2011 / Increase Horsepower on Branson 3820i? #1 D dc1w1951 New member Joined Jan 22, 2011 Messages 1 Tractor 1997 Branson 3820i By looking at the specs, the 3820i and the 4220i are identical, even the engines seem to be identical in respect to the displacement, etc. Is it simply a matter of timing to gain the extra 4 HP? If so, does anyone here know how to do this?
