| I know that this may not be a setup for everyone because it would require the entire setup I have figured. The picture included is very basic (windows paint) but is included to give a general idea. I wanted to switch to a single intake setup with a map for the ability to shorten intake piping and lower the amount of weight in the front of the vehicle. I have actually taken the basic design of half the plenum and where the runners direct air into the lower intake added a second 3" tube. This would provide air now to all six cylinders and still have the longer runners that Nissan engineered for low end torque. Since I was going a single intake manifold route, I decided to go with a intercooler much like TOM's fmic but with a dual inlet and single outlet. I figure with the intake cone gone from the front of the engine and moved to both sides (thanks to the map sensor), I could shorten the intake piping by probably 5 feet. I could also run 2 1/4" before ic piping and 3" after ic piping with a 75mm tb. This would allow me to keep the proper velocity needed and flow enough cfm through a 8" x 3" x 24" fmic. I guess my main reason for posting is opinions, and to all the TRUE engineers on this forum unlike myself, I would like to ask if the open manifold pipe right before the lower intake will cause lots of turbulence that could cause a lean condition. Basically, is this going to be a problem and if so will it outweigh all the positives I believe this setup has. By the way, this setup would be used with a Sport 700 style turbo.
