To the guy with the snowmobile...NO ONE CARES ABOUT YOUR SNOWMOBILE RUNNING 10s. We don't live in Alaska.
V8s aren't inherently balanced.
Are you sure? Typical American V8s aren't, but the European ones are. American V8s put two pistons on each crank whereas Ferrari splits the crank and has each piston on its own..
Umm...the physics of a American V8 is the same as the physics of a European V8. It has to do with physics not country of development. And yes Ferrari uses a flat-crank V8 in their 360 Modena (and I beleive older 355s) which is where they get that distinctive sound from. The engine still isn't naturally balanced, they use counterweights and other stuff to get rid of the vibrations.
Most modern engines are artifically balanced (as the excerpt about the Caddy V8 you posted above), but only inline 6s and V12s are NATURALLY balanced. There is a difference between artificially and naturally balanced engines. Mainly that artifically balanced engines use counterweights and other oddities that sap power. Granted when your making a healthy 400hp, the parastic losses of the counterweights are neglible.
note that when I say artificially balanced I don't mean that the engines are completely balanced, however the NVH is still reduced substantially to the point where its hard to feel the unbalanced-ness.
Btw, you have a 95 240 with the KA24DE, that engine is not counterbalanced <as far as I can tell>. Drive a 98 Altima (which shares the same engine which seems to be counterbalanced) and compare the way the engine revs to your 240SX. A world of difference. You can feel the harshness of the motor in the 240, but not in the Altima. However, I enjoyed the harshness so it wasn't a problem to me.
