It's not for originality fans, as the air filter casing becomes obsolete. I wanted perse the ram-air functionality, not just the scoops. Extra bonus, you get to see the engine you tried to detail too.
Using an original ram air plenum, made a copy, inserted a direct fit to carb shape, then made a second and final mould of it.
Now I could make copies all day long if I wanted
Here an old pict with the carb setup
Here with EFI, where I needed to remove 2 cms (less than a inch on the inlet), but the arc remains the same .
As there is a high flow filter in the ram-air. The filter on the carb/EFI, is there only because the car runs in the garage for now and I don't want something fall into the intake too easy. It has no reason to be on there when hood is closed. The cool air is directly sucked from the scoops when closed, and you can hear it.
Not original for sure, but you won't find much functional ram air more ram air than this
I also want at some point make a modified underside of the flaps casing originally vacuum operated. so they close/open on with key-on power. Just for the fun of it.
May you'd want to keep a casing for a more original look , you could do similar except you'd need to relocate the plane that touches/seals on the air filter casing rubber higher into the hood. If you go for it, count a good wekend of work and lots of measurements to get the arc right.
