Thanks for the feedback – I may really be nit-pickin here. I’m just used to getting a quick drop in the revs and more engine braking. If the idle adjustment is turned up it really exacerbates what I’m talking about, and brings up another Q. The only manual I have is the Haynes, and it really doesn’t go into how the mechanical governor works. When the idle adjust is turned up, and the engine has warmed, when I back out of the throttle the revs hang for a couple of counts before slowly dropping to the higher idle speed. This is in the carport, under no load, and say from about 2500 rpm. When the adjustment is turned back to normal it drops right off – just not as quickly as I would expect. I suspect this has something to do with the governor, or maybe the difference in the way FI works vs. a carb. The change in adjusted idle speed from fast to normal seems only about 500, and I can’t understand why it would cause this effect.
The weight of the flywheel just seems like the logical answer – it would also seem that the turbo motors should have a lighter wheel in order to get a quicker turbo response, but I am only speculating
