EVOM intake power gain

[fredmeister]

Anyone have hard facts on the power gain if any from a EVOM motorsports intake manifold kit?
I know it frees up space in the engine compartment but does it really make 10-12 RWHP as the company claims as well?


Any dyno numbers would be best appreciated to back up this claim.

I have tried to get some of these companies to show dyno data on their products but they won't do it. Stephen at AI has offered to test some of these things if they will send him the item free for testing but they haven't done it to my knowledge.

Stephen has said he dyno'd those intakes and that they do work. On and off the same, the same day etc etc.

Here is a snippet from an email.
