Okay so here we go I am just about done building my intake I know it's been forever but you know how life gets I the way
So at ross machine racing the D shaped plenum I Extrusion I bought they sell a throttle body for it but it's 90 mm
Its a ford 5.0 l throttle body that bolts up to it that they make in house now I am only going to have 2 1/2 intake piping from the turbo through the Internet cooler and to the intake that's a 1 inch jump from 2.5" to 90mm
Will it loose noticeable velocity at that throttle body into the intake I found d a calculator and it was saying 65mm what it's just a smidgen over 2.5"
If I do use a 65 mm throttle body it will still be going into the same plenum that will fit the 90 mm
So what do you guys think about that I know bigger is not always better it's a multi port design devided I that are ports ms2 fuel control Plenum is tapered towards the ear to keep velocity up as it travels down the Plenum maybe 6 lbs of boost
