Originally posted by Black Cottonwell, im neither here or there on it. of course every design is going to have its pros and cons and its fans and enemies. a lot of people feel that my plenum is too long and my runners are too long. you guys have shortened the runners, which in theory has been known to be better for boost, however isnt exactly true in ALL real life applications, consider buggatti and its intake design. the larger plenum is something i am a huge fan of, although looking back mine might be a tad too large at just +/- 5Liters what i would like to see, maybe is, which is hard when utalizing the stock lower intake, is a "velocity stack" style runner, along with an OFFSET TB opening location in reference to the positioning of the intake runners, so that as the intake runners draw air, they are not stuck in a vortex with the incomming air through the Throttle body opening. i would prefer to have the TB opening on the back end, with a slight taper at the back end its 180* shelf, to generate a vortex that wrinkles itself back towards the throttle body, thus generating an automatic swirl as the cylinders draw in the volume needed per stroke.
as you can see in the first pic i/we had offset the TB opening so that the runner provissions were not in the direct path of the intake runners making clear intake entry for less "negative" turbulance in the 2nd picture we used the "cup" style design to generate a float style curved vortex, to help enduce a swirl off the back side of the plenum to "in theory" help promote swirl through the runners. now i agree the intake work you guys are doing to the runners is amazing i wish i had the tooling to set up a jig myself and do such port work. A+++ for that, thats the one area i feel my intake lacks, even though i was able to carbide hone and mill mine by hand fairly evenly and accuratly across the board, the final product of that piece is top notch.
