Rusty, here is some interesting stuff from down under.  Stock wastegate ported to minimize boost at low rpm and bring it on at higher rpm.  This is the route I am planning on going whereever I get this 4th manifold done and satisfied with - probably way in the future {:>).

Hi Ed,

Thanks for the info.  I think I've seen those ads before, but seeing them again give me an odd idea.  Notice how they changed the compressor wheel to give more flow.  What would happen if I very carefully removed half of the blades on the compressor wheel?   There would have to be an even number to stay balanced, and even then, you'd have to worry about imbalance. 

Rusty (starting to scare myself)

PS- I won't be at Shady Bend this year.
