Thread: One Way To Build A '32 Hyboy

ah heck, Ken... Just get the aluminum out.... Heads would look better polished then painted anyway........

Dave-You are probably right, but I want to explore all the avenues first. A few years ago I decided to go Harley Davidson Pro Stock racing. So I built my own engine for that, so this project won't be as difficult as that.

Hey Ken, I did some research on the Ardun, since I had no idea of what you guys were talking about! Funny that one of the links was right back here in 2004, where Bob provided the following link to Ardun. http://www.ardun.com/ardun_histrory.htm
Very cool project idea!
Great idea for the power behind the truck too!

Ken, I was watching some car show last week and they had some clips of the Pro bikes running.............and wrecking!!! One guy's bike went into an uncontrollable death wobble, and he flipped off the bike. Some of the other bike wrecks weren't quite so bad, they simply laid them down.

There isn't enough money in the world to get me on one of those things.

Did you do the driving yourself?

Did you ever see E. J. Potter make a pass?

This story is good for sitting around and having a beer. I will be as brief as possible. When NHRA decided they wanted Harley Davidson to win Pro Stock it was too tempting for me, I had to do it. Ever since I was in my 20's I have built H.D. I knew all the short comings of all the engines produced by them. I was making some products for the EVO motor when this came about. I knew if it was going to be competitive it needed a new dry sump system and cylinder heads and intake manifold. When I was running pro stock cars I new the benefit from building my own manifolds. So we went to work.
I had a LS2 motor in a Corvette and for the life of me couldn't figure out how Chevrolet could get the kind of power and mileage out of it. So I took it out and pulled the heads off, and there it was, the way they made the runners and the swirl port design. So I made a intake manifold with 12" runners with a plenum so both cylinders were tunable the same and whittled a set of heads out of aluminum and made some roller rockers that bolted to the head instead of the rocker box for stability. (there is a lot more to this but, as you can imagine)
It worked perfectly the very first time
We did some crazy stuff trying to make more hp. Once I thought I was pretty smart on what was going on inside the plenum, but it wasn't responding the way I thought it would witha cam profile change. So I cut the face off the end of the plenum and screwed a Plexiglas cover over it and I was only 180 degrees off of what was really going on in there. I bought a chassis dyno and I beat that thing to death, for months. This is all normal behavior for someone who has ever run a pro stocker
I will finish this later here are some pictures of my beast with a couple of different manifolds.

What kind of HP did it make Ken? Very impressive bike mill.
