NO Mopar scoop except for the 69 1/2 A12 cars were very good.  They all, even the T/A hoods could not get above what is called the "boundary layer" of air that flows over the hood of the car.  This boundary layer actually creates a pocket of air that barely moves right on top of the hood.  That's why all racing vehicles have air scoops that stick up real high, to get above the boundary layer.

That explains how a lizard or a spider can ride along on the hood of a car for miles (until they get too ambitious and get up towards the windshield - bye bye lizard).

The original scoops may not be very functional, but they sure look good.  Nothing like a Challenger hood with a blackout center section.  :cooldancing:

If nothing else, it may help vent more hot air out of the cowl

If you still have the factory snorkel air filter housing, you can make a setup using dryer ducting (4" diameter) and have some scoops mounted just under the front valance, like the old Olds 442 cars did.  Just have to watch out for big puddles and such.

Thats the kind of setup I have seen put together. Seems to me it would work pretty good unless like stated that you sucked in a bunch of water. I would think some sort of screen would be in order as not to suck in leaves and bugs.

I think Goody has a similar set up but not that low, I think behind the grill somewhere....


You can get one of these air filter housings too, then mount to grill/under valance/to hood scoops....

Now that’s what I’m talking about, is that type of kit available, is it entirely home made or is that the factory setup for the Olds, (we don’t have much to do with Oldsmobile here in Australia).
Thanks

That pic was from this site: http://www.thegoodoldsdays.com/realoldsmobile.asp

I'm sure if you hunt around, you can find something similar for less money.  I'm sure there's somthing in Summit/JC Whitney.  :grinyes:

my junkyard setup


It seemed to pickup some on the highway pulls after I installed it. I definitely noticed a change on the cooler nights. I wouldn't consider it anything near "ram air", just "fresh" or "cooler" air. I don't like the idea of sucking air from under the hot engine bay..

No, they work. They are just not very efficient because of the layer of slower moving air right above the hood. I think its a great idea myself and with a healthy setup would have to be good for 10-15 hp I would think.

It has about 0-1% effect on your vehicle.  Unless the scoop gets above the boundry layer, it will do nothing.

I think that figure is too low. Even if the air is moving slower its much cooler and the engine is still going to pull in what it needs. It really doesnt matter if its a ram air effect, the fact that its cooler=denser=more power. I am not saying its a huge amount but it has to be worth more than 1%

IMO, it does add at least 5 psychological horsepower just by the "cool factor" the way they look.  :grinyes:
