I rounded off the inlet ports on the plenum back plate, hopefully this will help with a bit better non turbulent air flow
then I cut out a the top and bottom plate, I was thinking of putting in diagonal edges on the back. However it would make it a lot more complicated for no benefit. So I decided it’s probably best to keep it simple
heres a rough idea of the shape. Didn’t get much else done as I’m doimg a bit of research and also looking at getting some thick plate for the standard throttle body. I’m also going to make up a flange for fitting the standard idle control valve. So when it’s done it should be pretty straightforward to fit
