Active Hood Scoops?

[Scott e]

Has anyone out there made the hood scoops that are optional from FFR, made these working to let some air into the cockpit? I read that on the original Coups they where actually used. I been pondering doing this on my build. Not planning on AC so it would be nice to get some airflow through there.

Russ Thompson did on his gen 1. He used wood working dust vac slide valves. There may have been others, but Russ was first.

There's not a lot of room in the upper foot box on the Gen 3 Coupe. On the driver's side, you have the pedal box, the brake and clutch cylinders and lines, the steering column, the fuse box and wires, and the accelerator pedal mechanisms. Hard to find a route for a 2.5-4 inch diameter tube. If you don't have AC or heat, you will have room on the passenger side. Otherwise, that's were the evaporator, fan and heater core are.

It could be done. You will have to get creative and fabricate a few pieces.

Scott,
I've installed active cowl air ducts in my still being built (currently In Paint) Gen 3 Type 65/Daytona Coupe.
My coupe has the FFR supplied A/C system, so there was very little space on the passenger side to route the air hose into the foot box area. I discovered and made use of a small triangle opening in the chassis frame. Luckily there's a clear path to the drv's side of the A/C Condenser housing. I also incorporated a butterfly open-shut valve because I want to control whether air is entering the cockpit here in HOT Arizona.

On the driver's side I decided that I didn't want the scoop air to simply be dumped into the footbox more or less directly below the scoop because that's where sensitive fuse box, foot pedals and their actuators are located, as well as a lot of other wiring. At times there may be moisture or worse coming into the cowl scoop. I located the hose end at the far forward end of the footbox where there isn't much directly below the opening. This duct-hose system also has a butterfly valve, but it's located on top of the footbox. I've incorporated onto the bottom of this driver's side butterfly valve, a bottom cup which should capture any water coming into the scoop and direct it thru a small spout off to the outside of the footbox and down onto the roadway. Note: the black ABS tube protruding thru the scoop's cowl hole is just there temporarily to center the valve to the scoop hole.

Here's the early concept designs for both sides.

When everything is long term installed, I'll add those photos to my build thread.

Hope that gives you some ideas and helps!

Thats great stuff. Thanks a bunch. Great pics. Would love to see your build. I'm just getting started on mine. Where are you located?

Scott,
Thanks.
I'm located in Scottsdale, Arizona. The Coupe is currently in Temecula, Ca being painted by Jeff Miller Customs.
