SCCA regulations are very restrictive in some ways. For instance, I'm limited to 40mm carbs to supply an engine capable of 180+ HP, and certain mods aren't allowed. However, getting them to breathe is only a matter of being creative and spending lots of time making tiny improvements.

These pics show some of the mods I thought up to increase the Weber 40IDF flow capability.
Stock secondary venturi on the left. My ultimate mod on the right.

I found some tiny airfoil tubing at the hobby shop. It took some work to fit it to my setup though.
Attached Image
Keeping the venturi in place is a bit more challenging now.
The long bolt holds it upright and against the fuel inlet on the other side.
I turned off the threads so the airfoil tubing will fit onto the bolt.
Attached Image

Every surface/obstruction in the throat has been altered/filed/smoothed to increase flow.
The throttle plates have the edges re-worked to prevent turbulence.
Even the exposed pump jet tip has been file down.
