The transition casting can be swivelled a bit before the bolts are tightened. It helps to fit the rubber sleeve and tighten the clamps, before the casting is bolted down. This can improve the alignment. If this is not enough, the two bolts that secure the tube can be tackled.
The big end of the casting can be smoothed, but probably should not be enlarged. Study the step detail of the trottle body to see how it mates up. You are looking to get a surface match. The small end needs a great deal of metal removed, up as far as you can get. The only limiting factor is the wall thickness after the hose retention bump.
Have you seen the pictures of my reworked casting?
I am glad that you are happy with the result. It really is amazing how two different teams in Saab engineering could create such collective stupidity. Better gas mileage? Neat. This implies that the turbulance was affecting the engines efficiency off boost. This may have affected AF mixute via uneven air charging of the cylinders. The pressure drop of the stock casting would not be an issue at these speeds, as the trottle is almost closed, and the manifold is going to be pulling about 10"HG anyways.
Now we need a throttle body rework exchange business.
