I am going to see how durable this diffuser is and if everything works good I will make the middle one in about two months or so (Since that one is bigger and is going to be a little more, probably around $40 or so).
basslover,there is a section in Hucho's book which covers research conducted on bellypans and diffusers.The rear mods do not perform up to their maximum potential if everything leading up to it is not paneled.So the addition of the middle panel should improve what you have.-------------Also,Hucho reports that undercar flow will stall and separate if the diffuser rises at an angle steeper than 2-1/2 degrees,so your sheetmetal may be a little "fast."
