Johnny's plenum looks to have alot more volume than the cast C&L unit.
Incidentally, I just went to the track with the C&L unit, but I also had a different program in the truck at the same time, so I know the comparison is off, but my MPH remained practically identical to the stock plenum.
I need to go back to the track with the prior program in the truck to make a good comparison. However, I am not encouraged at this time with the "indications" the C&L unit has given me, in that I am not confident there is really much performance in it. Yeah, I know it's supposed to be 14HP, but I didn't even pick up MPH and it was a cooler night than when I ran on the stock plenum.
Johnny's sheet metal piece looks like it may make a much bigger difference in HP than the C&L piece (from a volume perspective).

so...JohnnyLightning... any word on the hp yet??? i like the look, i was actaully thinking about getting a sheetmetal intake made, but it would just be for looks, im still stock (for now) I like the design, hopefully everything works out .... how far away is your shop from Pittsburgh???
It's all about delta P. The larger the "plenum" before the rotors the better. I would like to see what the inside looks like though. Assuming there is simply a wall thickness from the outside shape, I'd like to see this piece have smoother bends. And the angle at the rear is less than optimal. Is it hitting the cowl lip area?
