I've always liked the dual over the roof scoops. I know, they don't really do anything. I know, they might actually hurt any cooling from airflow.

However, I 3d print stuff for a living. I have CAD skills and a crap ton of 3d printers. I could spit some out. Does anyone have a few rough dimensions? I could draw this up pretty quickly and have one running.

I'll share the files with you guys when done so you can print your own.

Thankd

R2 will go to the grave with me or to my kids. He's cool though. Fully functional, and screen accurate. Radio controlled.

Printing side scoops would be a better benefit and payoff.

Are you talking the whole 1/4 scoop or the ones that the Fiero store sells?

Sure. I would agree, but I just like the look of the over the roof scoops. Side scoops would run quicker since they could potentially be run flat. Regardless. This would be on an FDM machine and the finish work would be a lot on anything. This is a poorly done part and you can get better than this but just for illustration sake you would be starting with slightly better than this for surface finish.

over the roof scoops would be nice but hell with the heat of the engine area almost have to 3d print for molds and use the molds to make them in fiberglass. Side vents would be best again 3d printed buck and a vacuum forming machine that can vacuum 3/16" material. All are due able but would cost a reasonable investment.

If I run them out of polycarbonate they will be fine. Glass transition temp on PC is 300-ish degrees F. Heck even Glass transition of PETG is about 170 degrees F. I think over a decklid grill they would be just fine.

Edit to say I run bits and bobs off FDM machines all day every day that go on vehicles in extreme conditions...straight 3d printed from the correct material works just fine.

Took some quick measurements and drew this up in about 30 minutes. Inspired by but not exact to the regular fiberglass scoops. Off to the 3D Printer.

You expertise in printing sounds great but could it have a negative effect?
The engine compartment in a Fiero gets its cooling mainly while you drive when air is diverted from underneath and out the vent grills at the sides of the trunk lids. By attaching an air scoop over the roof and over those vent grills, you create positive pressure going the other way. Wouldn't you be defeating the engine compartment cooling effect?

I have a suggestion for you; Set it up with a grill on the back side and an internal air mixer so the air coming IN the scoop above creates a venturi effect and draws MORE air from the engine compartment.........Just a (Crazy) idea....

I guess I could.

I'm going to do some actual testing. Yes it will reverse airflow meant to keep things cool. However, maybe...just maybe this will improve cooling. I would think some higher pressure, higher velocity air coming in would be cooler. Worth a few spools of material to find out. Do some before and after engine compartment temp tests.

I'm thinking no since on my biggest machine just the over the roof part will take 23 hours to make one.....yikes. It's not fast but the machine does all of the work.

this is why you just print 1 (designed differently) so you can make a fiberglass plug then make as many as you want faster.

But I need 2, and I hate fiberglass work. That's why I'm 3d printing them. Pull em off, sand, paint, install, done. If you have a 3d printer you can make a set too. Hate hate hate fiberglass work.

I have a single over the roof scoop on the drivers side only which I prefer and I use to here the same comments. So I became creative and made it a functional Ram-Air scoop as part of the 3800SC swap. So now when I get heckled by any non believers I urge them to lay a $50 bill on the sun-roof in front of the scoop while I mash on the gas!! I may modify the original side scoop and ducting to help ventilate the engine bay.

Curlrup you have some terrific skills and I'm sure the members on this forum could keep you busy for a long time. I just spoke with Alexa and she says you're only 34 miles from my location as the crow flies. I'll let you know if I need something you make.

I know we all know The over the roof scoops are not practical ,but in my opinion, They look very cool. I have a set myself ,but am only using one scoop on the passenger side. I put a carbon fiber wrap over the scoop just to dress it up a bit and get a lot of attention. Good luck with your scoops. I’m sure they’ll turn out great. Just a suggestion, Are you interested in making the “Stealth Wing mounts? Those are very small, maybe easier, and have always been a hot seller in the Fiero community. If you would like to make a set, send them to my house. I’d be more than happy to test them and won’t even charge you!?😂😂 Just a thought, You definitely have talent and we can use someone like you ,in our community. Good luck👍

I don't want to muddy Curlrup's thread with another topic so I'll just say this,

Although they are easier, one of the main failure points was the "overhang" of the wing once it was lowered and moved towards the rear. People would not read the warning pamphlet that came with each set and they used the wing to slam their decklid closed.....which in turn snapped the wingstands in half. That was one of the issues with making a truly "stealth" wingstand that was very thin near the back, otherwise to compensate, it would have to be machined out of aluminum which would drive up the cost.

If you have any questions about them, feel free to PM or email me.
