This is how I had set it up:
I am disappointed and surprised that it did not work out as I had anticipated. The Sensors are in a 3" pipe, and the sensor bungs are extra tall. I guess having them in one pipe is the big issue here.
I am thinking that if these tall sensor bungs are used in 2.75" tubing, they should be good for 550whp or so wit these tall MAF sensor bungs, as this was good to about 550whp on the turbo kit with low profile MAF sensor bungs.
Ideally, I will try to do it with 3" pipes, but it will be extremely tough since the room to make a Y pipe is at a premium. May have to use some tighter radius cast pieces...we'll see when the car comes back I guess.
One way or another, I will make it work.
