The black and white pics in the lead post of this thread are of Wayne's system. I took those shots in the mid 1980s. He has quite a tale to tell concerning his tracking and acquisition of this rare RA system. BTW, the color photo in the same post is also of Wayne's car. It was taken at the 2001 Red Wing, MN POCI convention. I believe that that was the first time the car was shown after its restoration. Wayne is the original owner of this '73.

I, and I am sure a few others here, would like to hear Wayne's story.

I met Wayne Hejny at the GTOAA Meet in Minneapolis back in 1990. We talked about his '73 and he told me about the Ram Air system on his car. I took a ride up to his house and got to see the complete system. If I remember correctly, he worked for a Pontiac dealer when he bought his car and scoured the country through his parts connections for all the parts to put the system together before the parts were pulled by GM. It was very cool to see a functional system. I'll have to dig out my pictures.

1. Wayne's 2. Tom Goad's '73 GA wagon 3. Brian's friend with Jack Hoffman's 1973 Grand Am SD-455 4 speed 4. A collector in Mass. sold a complete setup for upwards of $10k within the last 4 years.

Somebody paid more for one of these systems than what most of these cars out there are worth, but nobody will pay $500 for an accurate reproduction? That's just f**king amazing.

We would have to supply the shirts since the tightwad owners are too stingy to even buy the shirt.

I have a partial system -- basically the pan and the foams. The only major part I don't have to make a complete system is plastic lid which is the most important part.
That complete system was supposedly new in boxes. Anybody know the current owenr or is he keeping quiet? I heard $5k was the asking price, but a bunch of other NOS parts were sold along with it.

We might add a couple of '73 engineering cars to the Ram Air lineup. At least one '73 GTO and a '73 Grand Am. Who knows what became of the system on these cars.

Unfortunately, they probably stayed with the cars as they were crushed.

The lid that is on Phil's car (formerly Jack Hoffman's) may be from one of them, who knows. Jack purchased all of his parts over the counter, except the lid, which he got from a friend working at GM at the time who said it was "collecting dust on a shelf". This was around 1973-1974 so who knows.

It would be interesting to see dyno test results with and without the kit to determine any real performance difference.
Maybe if it could be proven that it would boost HP and exactly how much improvement, more people would be interested in it.

I can count on one hand how many 73-77 A-body Pontiacs I've seen actively racing at the drag strip in the last 20 years with modified engines on one hand, and have a finger or two left over.

Probably doesn't, I don't think any of them do.
The only scoops that get above the barrier layer are the early Formula ones and the in-hood ducting on those is so restrictive, I'd be surprised if they breathed at all. Can't beat the cool factor however.

Probably an insignificant difference since there was no carb calibration change to account for the ram air. Since it failed noise regs I'd love to hear how it sounded.

I've had the pleasure of driving Phil's car hard, and from inside the car it didn't sound any louder. Phil's car has mellow mufflers on it, maybe not much louder than a stock muffler from back in the day. It talks when you get on it, and doesn't give that "whoosh" sound like Gleason's car did in Smokey.

NACA ducts are different. There is a reason why they are used on most race cars and airplanes. NACA duct From Wikipedia, the free encyclopedia Jump to: navigation, search Artist's concept picture of a submerged inlet for a jet aircraft The NACA duct or NACA scoop is a common form of low-drag intake design, originally developed by the National Advisory Committee for Aeronautics (the precursor to NASA) in 1945. When properly implemented, it allows air to be drawn into an internal duct, often for cooling purposes, with a minimal disturbance to the flow. The design was originally called a "submerged inlet," since it consists of a shallow ramp with curved walls recessed into the exposed surface of a streamlined body, such as an aircraft. It is especially favored in racing car design. Prior submerged inlet experiments showed poor pressure recovery due to the slow-moving boundary layer entering the intake. This design is believed to work because the combination of the gentle ramp angle and the curvature profile of the walls creates counter-rotating vortices which deflect the boundary layer away from the intake and draws in the faster moving air, while avoiding the form drag and flow separation that can occur with protruding inlet designs. This type of flush inlet generally cannot achieve the larger ram pressures and flow volumes of an external design, and so is rarely used for the jet engine intake application for which it was originally designed, (the North American YF-93 and Short Sherpa being exceptions.) It is, however, common for engine and ventilation intakes. http://en.wikipedia.org/wiki/NACA_duct |

Useful for cold air intake only in this application (mid seventies A body hood).

Chris,
The question was would it boost HP - I contend that it wouldn't and for that matter none of the RA setups would. If you need fresh air, that can come from anywhere - the dual snorkel or open element prove better. Just my opinion.
