So tough, when are you going to start building it for us, haha j/k. But your right, whoever this guy is layed a good foundation for us to build off of. Just for the heck of it, I'm going to go see what kind of quote I get from the local machine shopThe overall idea is sound, but the runners are too short and the spot on the front that's dented in (his is made to face rearwards w/the TB) is obstructing that runner's flow significantly. It would be fairly easy following his basic idea and doing it in aluminum with radiused inlets inside the main plenum. That should pick up mid to top end hp tremendously w/a 90mm+ TB hooked up to it with some proper cams and headers to back it up.
