Hi Dick,

My only point is, that I also made earlier, if these engines are of such a superior design, they should be putting out significantly more power than the Taurus. Even if we even things out and say the Taurus is equivalent in power to the ZDZ40, where is the advantage of the superior design you suggest? Like I said, I too think rotary valve motors have more potential than a piston port motor, but at least from the data I've seen on the ZDZ 40, it hasn't realized it. One element of a design will not make a superior motor. It not only takes a good design, but flawless execution(precision). You're not going to ever get the maximum potential out of a motor from a mass-produced engine. A hand massaged (blueprinted) ZDZ40 will be better than 98% of the stock mass-produced examples out there. Ok, ok, I'll shut up on that.

>>The realized stuff tho is pretty good!

Agreed.

>>My new Rear Exhaust is on the way

I've very interested to see how that performs.

>>My own goal is a 6000 rpm setup-

A Zinger Pro or Menz S 24X8?
