You have no idea what you are talking about......

Dyno-jet dynos are mostly inertia dynos that calculation HP by measuring how fast a bike can spin a certain weight drum, up to a certain speed, in a certain amount of time. By tapping into the RPM signal on the bike, the dyno software can determine the actual torque of the engine. A DJ250i is a brake dyno just like a Factory Pro EC997a in that it also has a brake and can do fully loaded pulls. Usually though, for WOT pulls, DJs are run in inertia mode because its not as hard on the engine and tires etc. Dynojet 250s are the standard in the sportbike industry and they general numbers they produce are what most of the industry goes by....(rag mags, online mags, adverstisements etc) but it is true that numbers can vary greatly for many different reasons....

The reason I mentioned Johnnycheese as well as Tejas Motorsports, is I have been on both dynos with the same bike in the same day and made within 2hp of each other....I have done this same test twice with both of my bikes. Thats close enough for me.

If you dyno that new honda 1000 on Metric's dyno, expect 140-145hp, on a DJ250 it will show 155-160hp. Nothing wrong with either one...... Thats the reality..

319hp@14lbs(pump gas), 435hp@29lbs(race gas)
