1. The intake on the SHO is one of the nicest intakes every created for any engine ever. Period.
2. From SHOtimes.com "Because the engine is not boosted, it runs cooler. It supplies a smooth flow of power right up to 7300 rpm. At this point, a rev limiter starts cutting out cylinders to hold the rpms steady at 7300. This technique for preventing over-revving is the result of Ford's Formula 1 racing experience. This rev limiter is not designed to protect the engine, but to protect accessory drive components. The engine itself has been tested at rpm's greater than 8500." - The engine makes power well past 9k rpm, but it starts blowing accessory components.
3. Yes, the klze revs that high because it makes power like a 4banger. It has to rev that high.

I love both engines, but the SHO engine is nicer in every way imaginable... except for price on performance upgrades.
