Hood scoop

[ND74ROADRUNNER]

Has anyone made a functioning cold air intake on a 73-74 roadrunner hood using the original hood where they have the fake intake?

There's a fairly long thread on this site.

Any air from outside the hood is better but the stock factory hoods like that are not very effective. Did one on a Challenger years ago and it didn't make any difference but this topic could be a good one. I know many here have some experience in the factory scoops etc. A buddy of mine put a T/A hood setup on his RT Challenger and said it didn't make any difference either. Low rise scoops don't catch enough air but on the other hand, hoods that use the low pressure point at the base of the windshield do made a difference and is why you see so many Mopars with them. It's also the reason your floor vents work so well. The boundary layer of air going over the hood is slow moving but has it goes up and over the windshield, the air is moving faster and it creates a low pressure area where the cowl vent opening is. The engineers found that out a long time ago.

Simply opening the holes on Challengers, and 70 Super Bees (or any that have screw on block plates), will at least let hot air out, and at speed, force some cool air in, to blow past the engine on it's way out, below the firewall.

The 73/74 RR hood does not lend it's self to this as the simulated vents are all cast a one solid part.

There are some creative ideas, on the other thread...
