600 horse power...very good. Lifetime of 1000 miles...not so good. Thanks Jerry. That is a little better than the drag motors that make 1000 horse power for about 1 minute. But...not much. When I was making hot rod motorcycle engines the first question I would ask was...How much money do you have? Still valid today. I like the idea of balance in the intake. I do. But so many things come to play. Can you make it better? Yes. Will you notice? Maybe. To get an engine to work very efficiently at a single RPM is not so hard. To make it work over a wide range of RPM is much more difficult. So many things change as RPM changes. That is the reason that compressing the incoming charge works so well. Boost makes up for lots of issues. Right up to the point the parts leave the engine. Then out put equals 0. Gotta love Hot Rods!
