EVO 11.5 Hotside, anybody try it?
Here is this pic bigger so everyone can see it;
Judging from the pics I have seen, this piece looks very nice. Has anyone sent one into Forced Performance to have it cut for the Red, or Black's turbine wheel? Or has anyone had one cut for the HTA Green's turbine wheel yet?
I really like the fact that the flapper valve on this 11.5cm unit is larger diameter than the factory 10.5 single puck flapper valve. The factory flapper does not allow for much enlarging of the wastegate bypass ports.

larger flappers blow open easier than small ones. there is spool speed loss with early lift.
I would be worried about material . the divider wall breaking off will ruin your day.

Given identical wastegate bypass port diameters I would tend to disagree with this. In the first place the larger diameter flapper valve would weigh more than the smaller diameter valve, given the same metallurgy. Wouldn't it?
A higher mass flapper valve would be more difficult to lift given the same seat pressure.
