wasn't there just a post here recently about how you actually GAIN hp by REDUCING flex of the crank? I don't know, initially I noticed the bog, but you'll notice the engine struggling less above 5k, which is where all of our power is. . .I'm coupling my DMD'ed engine to a fidanza, so I would assume you'd be able to ge to the sweet spot faster and smoother with better power delivery since your crank isn't whipping everywhere. . .eh, to each his own.
