Ram Air opening question
#1
My car is still at the shop but have a question on the ram air hood.  I see these two items listed now and then, links below.  Are the "grills" for non functioning ram air hoods or are they a part of an active hood?  The scoop "inserts", where to they go and what is their function?  I do not believe my hood has these inserts, all I see is paint and then the flaps and I think my flaps are remaining in the open position so will need to address that when I get it back for my work to begin, I assume they should function via vacuum when accelerator is in use.

Grills are non functional, completely block off the openings. Your assumption is correct.

When the engine is running normal the flaps are closed when you go full throttle and the vacuum drops the doors open. There are not plastic inserts in the hood when you have RA.


When a man is in the woods and talks and no women are there is he still wrong??

Are those grill inserts part of those grill block offs for the non ram air?

Yes, the block off plates are used on cars that have the NASA hood but, does not have the ram air set up with the flappers. I have been looking for a set of good actuators to get my flappers working for the last couple of years, just in case someone has a set they will part with.

I understand that the plastic grills are for the non ram hood but are these inserts (see link)part of that system for the non ram hood ore do these also go with the active ram air, the loom like some sort of trim ?

 The metal insert are on both functional and non-functional NASA hoods (NACA if you like) The plastic inserts are held in with screws. On ram air, the plenum butts up to it. I don't have R/A so just going from memory.

This is a close up of the only current picture I have of my car's hood. Are those inserts there and just silver so I am not noticing them because they fit so well they just seem part of the hood? Again, this Mach 1 is all new to me never really having seen many in the past or not paying close attention.

 I can barely see the plastic inserts, but if it were me, I'd paint them flat black for contrast. The problem with them is they get dirty and hard to clean.
I'll get some close-ups soon and post them for you, Stay tuned!
