Yep,</p>

I gotta agree, in general, (I don't deal in the HP calcs) with Dar on this one. Some folks are leery, for some reason, to get these 'long strokes' down into their torgue band of rpm. These engines are designed/timed to run there and the pipe/setting plays a significant role inachieving it.

Don't forget about the engine/prop unloading some in the air.</p>
