I do not know. Do you have flow bench data, comparison dyno data, etc to support it?
Extrude honed manifolds have done pretty well lately on Evo 8's because the R&D wasn't put into alot of the manifolds sold -- they were just copies of old DSM manifolds that were modified to fit the Evo 8 when it came out so people could make money. Lately, more companies are actually spending the R&D $$$ to make better manifolds for the Evo 8 setup. Wilson's V2 Extrude honed Evo 8 Intake Manifold is a nice piece. Unfortunately, it is not usable on our platforms, or engine layout.
The manifolds that the Beyond Redline Performance SMIM was tested against were current production SMIM's that are proven also -- they made good power in relation to the stock intake manifold on Car #1 and #2 in the past. The Beyond Redline SMIM put down very nice gains over the other SMIM's, and it made a serious improvement on my car. I think that my old SMIM just couldn't keep up on a 2.3L with the GT40R, and was choking itself. When we put on the Beyond Redline SMIM, I was completely shocked that we gained that MUCH HP!! I was hoping for 30-40AWHP over my old SMIM, and was not expecting 100+AWHP at the same boost levels and same ignition maps, while reducing fuel injector duty cycles, improving efficiency of my fuel maps -- heck, this manifold flowed ALOT MORE AIR than the old SMIM.
