[QUOTE=ZZcamaro;157303]But what do you think would be the most reliable?
I would also think the N/A motor would be more fuel efficient....you are making the HP with less air since there is no forced induction.
I am considering building a motor next winter, or I would buy a blower this spring, and maybe forge the internals next winter.... Can't really decide, but I must say it would be SICK to put down over 600 at the rear all motor[QUOTE]
Didn't see your post til after I posted mine.
No. A NA motor with big displacement and high hp would not be more fuel efficient. The motor is having to work harder to flow the same air. Which it would still have to flow lots of air to make good power. And modern superchargers are efficient at low rpm so there wouldn't be a lot of drag forcing your engine to work hard at low RPM.
Not to mention that the cam that would be needed to make 600 hp at the wheels would be rough and make your car idle really crappy and possibly not even make great power off the line.
Trust me. For high horsepower daily driven cars, FI is the way to go.
