There's these things, I think they're called JATO units....
Yeah, you have 750 HP -- at 6500 RPM or so. The important question is how much HP do you have at 1000 - 1500 RPM which is the RPM that you'll be starting at most often on the street (assuming this is for street use)?. The benefit of a flywheel is that in situations like that, it stores up energy so that the engine doesn't stall when the clutch is dropped. One of the trade-off's of an engine with light rotational mass is that the clutch wear is higher. Now if you have a race car where the engine gets stripped every one to two seasons (maybe 100 hours of use), that may not be a big deal. But for street use, it can be a real drag replacing the clutch every year or more.
