im also of the opinion that a bigger plenum is better in a turbo app. and the design isnt as important as on an N/A app. u want a big plenum so as soon as the valves open u got 3-5 liters worth of boost waiting on deck to go into the cylinders. i really wanted to go with a design somewhat similar to the one above but we were worried about space and mark didnt want to go to big on the plenum (and i didnt have the materails to make it either). i actually thought it was going to be bigger than it was, but no big deal on my end and im sure mark was a little happier also.
