However the new plenum isn't bored out stock like this, he welds on a sheet metal style one. The resulting TB location is very close to stock.
He thinks that for most street cars the current SMIM offerings have too short of runner length, but you can't really get around it unless you use cast aluminum for a curved runner. So he's going this route for a more street-optimum RPM range manifold. I'm pretty excited to test one out on my car vs. the JMFAB intake.

That was tested, a while back too. I have no idea how much actual research went into it, but they did the same thing w/ an evo manifold. It fell on its face
Looked promising though
