Re: intake manifold design
The reason i suggested a small plenum was looking at a few examples of factory turbo motors.
I'm thinking of two specific examples. The 405 T16, which is the production version of the pikes peak car. It has almost no plenum and short runners in a 1-2-4 design. I've seen this plenum cope with 400+ hp
The other being the ford cosworth, again, short runners, small plenum. Packaging concerns probably played a fairly large part in this. Either way, both cars have great tuning potential and rarely do owners change the inlets.
You can correct flaws with cylinder trim and to a certain extent charge robbing will occur with any design, but i still don't see the point of a large plenum on a turbocharged car.
