Have you ever ridden in a 350+ HP automobile? They are *exceptionally* uncomfortable (remember: performance and comfort are at two opposite ends of the spectrum). Cam action beats you to death. You have to shout to be heard. Scratch the word "idle" from your dictionary. Ever notice no one drives "high performance" cars on a vacation?(would be an endurance test). Horsepower is like everything else in life: best used in moderation. Why don't you settle for 200 or so and spend the rest of your development budget on an upgraded sound system YOU WILL STILL BE ABLE TO HEAR. Bill. >--- In dmcnews@xxxx, "C. C.
