I've recently purchased an SVT and am looking to make a few performance mods. The most glaring problem (PLEASE correct me if I'm wrong!) is the UIM. The airflow pattern just looks silly. Air goes past the TB and Imediately has to make 2 90' turns..then a bit furthur along the intake tract another 90' turn to the 2 main rails. Finally to get to each intake tract (all 12) yet another almost 90' bend. To me this is totally counterproductive to making usable HP. I know everyone wants to add all these special airfilter/intake kits to smooth airflow and gain massive HP ( what? 2-3 if that?) only to get it negated by the brick wall intake manifold. I think this is the main reason why there's such a small performance gain by adding any type of intake kit.
How to remedy this problem (besides muting the author)? Picture the TB about 6-12" closer to the drivers side fender. Then picture the intake stretched out to the TB. A couple of major bends just got smoothed out and a hell of a lot less turbulence in the UIM.
I think this would hell a ton in making HP regardless of it being stock or modded.
