Yes. I am looking at making a pattern for just the bottom 90
degrees.
If I could only figure out how to get the cores in the mold.

I now understand core boxes, core prints, drags and copes.
I still don't fully understand curved parting lines.
I need to take a trip up to the foundry and have a look around.

What about something like this Paul, from the Mazdatrix site

Not tight enough. Won't fit the stock turbo or my cowl.
Actually that is the top 90 degrees and adapts a weber
carb. Looks like it is tuned for 8500 RPM to 9000 RPM.
Might work pretty good with a 2.85:1 gear box.
A lot of the gyro guys use these.
