The manifold on the old school kits had the turbo blowing directly at the back wall of the manifold.
That is because the fuel would desperate and go to the outside of the scroll. The centrifugal force
will give you a stream of fuel on the outside of the exducer(?) It needed to hit the wall on the backside
of the manifold to break up and some what reatomize.

forgive me for being ignorant, but what is it that gives the plenum style an advantage (other than space savings and simplicity)? Thats the best thing about these projects, I can have fun with it and learn more for the next project.

A plenum adds to the volume of air that is being pressurized so that when an intake valve opens up to fill the cylinder, the pressure drop in between the turbo and the cylinder (manifold and plenum) is smaller.  It helps to keep the turbo from surging and provides smoother power delivery.

A plenum should be at least equal in volume to the displacement on the engine on a four cylinder engine.  Double the volume for a twin and quadruple it for a single.

heres how it sits now, hopefully i'll have some time to work on a seat this week. I originally planned on finding a sportster tank or some sort of peanut tank, but this big ol' blue thing is starting to grow on me. And its free, which leaves a little more cash for the necessities. I plan on building a springer seat and forward controls. I'm 6'3" and 210. I haven't really decided on bars yet. I like the look of clip ons, but i'm thinking they might be a little too low with forward controls. I'm thinking maybe drag bars. Any other bigger guys got suggestions? I don't plan on riding this thing across the country or anything, but I also don't want to look like a monkey bangin a football when i ride it.

yeah I think drag bars would be fitting..  and if someone says you look like a monkey banging a football,  remind them your motorcycle has a turbo... a turbo.  yeah.
