This is not a stupid question- the V-band 44 flows more than a 46 due to the difference in technology- Tial only makes the F46 (our Porsche waste-gates) only for the Porsche market, no-one else really uses the F46. The V-44 has a much better design then the original type.

James- this is because my turbo is bigger than yours and also has a T-4 housing with tiny little stock sized primaries. Because my hot side flows a lot more, the stock waste-gate setup is in-effective because the turbo is even easier of a path for the exhaust gasses than the waste-gate is. This is also a product of the ridiculous velocity I had with the stock sized primaries.
Your turbo (35R w/T3 hot-side) is the last step before really having to do something creative with the waste-gate/ primaries/ turbo flange/ etc.

Next time around I'm kicking boost-creep in the face with twin V-44s (over kill, but I got a second one for cheap)
