I got to see a real race 348 with a special engine done partly by michelloto of course. One of the things I noticed was different from stock intake plenum that looked just like a oem stock unit but with longer runner and higher bulge over the runners consistent with a higher horse power modified motor. It could have been easily overlooked it looked so stock. We know what HR's do. Do you think for acedemic purposes you could find optimum volume and runner length to maximize HP/Torque at specific RPM's as in compute a curve? A clue of how to do this which is over my head is http://www.me.psu.edu/me415/SPRING02/intake/intake.html. What do you think? Also, how does such a curve get effected by variations in pressure from changes in ramair effects by different airbox configurations etc. upstream of the throttles? Mitch you did such a great job on the 355 suspension analysis how about taking an acedemic stab at this?
