A friend and I were just talking about riding down from southern NH to see the museum sometime soon. Lots of cool stuff in that motor. Can't wait to see it.
Stop by anytime! Friday is the best day as all the techs will still be on duty.

On another note, the ignition was the problem. I just threw a dyna s ignition on the bike and it made 106rwhp @10krpm 6lbs of boost. Going back on the dyno to dial it in more this weekend. Going to turn it up to 12ish pounds of boost and aim for that 130 number on pump gas. Video coming soon!
Getting there. ;) As Scotty so eloquently put it....The Power Arc should be named Power POS.

The PA POS required a smaller spark plug gap than stock, due to less spark energy, even when they worked. Once the engine got into boost, the added pressure "blew" the spark out; the RPM wasn't as much of an issue as the amount of boost.

 Dale Walker mentioned the Zenith carb on his turbo drag bike running the float bowl dry.
  I've been watching to see how this project shakes out.
  My bike has an ARD CD version mag but I noticed how far it hangs out in the wind. An electronic ign. has no wind resistance penalty.
 If it ever gets an engine built, I'd like to put my bike on the mile/2K somewhere. Arkansas probably.

Looking for the AF. Power line for 500+ bush's is nuts. Funny thing is all turbo's produce that real smooth mountain side of power when running right.....doesn't matter what they make for final power.

Hello, is there anything new about the turbo kit conversion. It would be really interesting to read whether the engine runs on the road.
