Ram air?
I know turbos systems are already forced induction but would a ram air hood help at all?
My thought process is......
It should help spool the turbo a bit faster because air is being forced to it ( obviously at zero to low boost ).
Many of the intakes we have for our cars still involve sucking warm/hot air in to the engine. Where as this design would allow you to get outside air.
Here are a few pictures of what I am describing. I chose these since I am more familiar with Mustangs then RX7s.

Now I have seen hoods for the RX7 that have similar opening but never where anyone has collected the incoming air like this.
Do you think this would make any sort of difference with either spool up time, or benefit of cooler air?

Craftcompany in japan do on their track RX7s in japan.... Whether it is to take in fresh cold air, rather than engine heat, or actually ramair, I'm not sure. Maybe a mixture of both.
Look either side of the FMIC
I assume these ducts are for the intake, its hard to be 100% sure.

How sure are you that those "ram air" hoods on the Mustangs are all that functional? Dependent on speed and some other factors, seems like actual air-flow might well be above those openings.
And if such "hood scoops" were on FD, I'd want them to be sealed to the intakes somehow, so that it couldn't contribute to high underhood pressure that would impact flow through an intercooler. But maybe with "ram air" that's a given.

The only car that I've dealt with that was succesful with the ram air intake was the Trans-Am. And that didn't really come into play until ~60mph since under that speed it was an ineffective mode of forced induction. I don't understand how a ram type intake connected to a turbine would affect its spool rate. The compressor wheel spins and sucks in air. The rate that the wheel spins wouldnt (I think) be affected by slamming air into it. I think that those ducts on the Craftcompand FD are for the oil coolers. Not sure.

I don't think the ducts on Craftcompand FD are for the intake. If you notice the passenger headlight cover already has a duct that's designed for fresh air to the intake.
The driver side duct definitely isn't for ram air since there really isn't any way to route it to the turbo. Also Drier ducting wouldn't make a very good ram air system. I think the larger openings are for oil coolers and the ones under that are for the brake ducts.
