Dynojet’s mobile dynamometer and support center was on-site at the annual motorcycle rally in Sturgis South Dakota.   We love measuring and making power, it’s in our DNA, and this year there was a particular 2010 Fatboy Lo that we wanted to show off.

Touting a Sean Ray Turbo System with stock 96 Ci pistons, CNC ported heads, SE cams, and 20 psi of boost on race gas this bike is capable of 250+ rwhp!!  The long block is all stock and this bike isn’t just a dyno queen, it’s designed and built to be ridden…..hard. The best part is that it’s seamlessly smooth, pulls like a freight train, and utilizes the stock ECM safeguards like knock protection and temp vs spark advance compensation.  At the event, the bike was run in “street trim” and burning pump gas to the tune of 140 rwhp. Pretty nice for a fairly stock H-D 96ci engine!!  Oh yeah, most importantly the EMS system is a stock Delphi ECM with a Power Vision flash, Power Commander 5-PTi with integrated 3 bar TMAP sensor, and custom high flow Delphi fuel injectors.
