Funny as I actually disagree, loading a bike on the dyno is creating an artificial situation, almost any load you apply to a turbo bike on the dyno to slow down its acceleration rate is a situation that will never happen in real world usage. I am not saying that loading the dyno is not useful, but you refer to loading it more on the dyno to match its load at the track, the acceleration rate at track is extreme, it has no real time to build the type of load you are trying to explain as it is accelerating, apply more load and it will make more power and spin the tire or wheelie. You make mention that it is only a 3 second pull, cool, its a single gear pull, 3 seconds, these bikes run down the track in under 8 seconds, using all 6 gears, 3 seconds in one gear seems like a fair amount of time to me, detonation on a kit like lzbrown is controlled with cool intake temps and is virtually non existent, which allow us to run even more timing then a non-intercooled system, and typically leaner air/fuel ratios.

Typically we will always pull some timing on a boosted bike. My 600 hp RCC Ultra has NO timing pulled . . . because of the low intake temps, I do not have to retard the timing at all. . . .the bike is a monster both on and off boost and even though I have been riding turbo bikes for over thirty years, this one still can scare the crap out of me when I turn the throttle . . .:omg:
