Here's the same bike breaking the dyno strap at 934 hp.

I've always wondered why motors are left to decel in gear instead of pulling in the clutch to let it free wheel. Does it have something to do with the dyno drum? Why always in the next to highest gear instead of high gear?

 

[Sputter]

Well, yes kinda! On a turbo you don't want to pull the clutch in at high rpm as the turbo is spinning at high speed. If you drop the rpm while the turbo is at boost and very hot the oil pressure drops, not a good idea. The last hear is overdriven and the gear below is usually closer to direct.

 

[WuzzaCBXRider]

I've seen the same procedure on non turbo engines though.

 

[Sputter]

Yes, on a non turbo it would just be an added operation to pull the clutch in, let the inertia bleed off, downshift, run back through the gears to get to where you already were.

I wonder if that guy would let me ride his bike.... I only want to take it down the block

 

[Sputter]

Sure he would! I think it requires a $80,000 cash deposit though.

They need to let the bike run down in gear as Dyno's measure 'Drag Power' which is the power losses through the transmission / chain etc... This gives the estimated power at the Flywheel.

As for the gears, it's always best to run a dyno run on the gear setup that's closest to 1:1 (One turn of the engine = one turn of the wheel) ... Most modern machines thats 5th gear.
