In order to increase underhood cooling, I'm attempting to make screen covers for my headlight openings. I'm having a difficult time forming the material into a clean shape and a mounting system. Tried using old covers as a form, various mounting methods. Anyone come up with a good looking, clean method? TIA

 

Not sure of year, guessing 1st gen, but why not just use a headlight cover and form in a NACA duct? Would apply to any gen I guess. I took the head light bucket cover, put in the NACA duct from the underside then put in the cover back on and riveted on a couple of supports to hold it on then fed the hose to whereever you are trying to go, radiator, airbox, etc. Would look better than screen for a head light cover, and looks somewhat trick, like we actually know what we are doing.

Sorry, yes 1st gen. I've already removed the headlight covers. Had to drill out all the screws. I'm trying to minimize weight and get lots of air into the motor. It's at 2000 lbs. now with a roll bar and 2 seats. Thanks for the suggestion, though I'd hate for someone to think I know what I'm doing.

 

What are you trying to do, help cooling or help cold air for the intake?

 

Here is my thinking. Weather you are going for increased cooling, trying to feed air to intake, etc, you would be better off with the NACA duct. The weight is very minimal for everything, maybe five to seven pounds with duct, cover, hose, whatever. Then run it into a airbox, filter housing, though for intake I wouldn't run it straight to any velocity stacks or carb throats without something to filter the highpressure air. Debris being forced in can't be good for a rotary diet. It is just if you are going to go through the trouble to make a screen and make it fit, not get crushed, why not spend a little more time and direct it to exactly where you are trying to supply more airflow. Tony Rivera did exactly this same thing on his EP RX7, I think feeding his intake, as he only has it on the the passenger side. And he definitely looks like he knows what he is doing. lol

 

The screened openings would be a combination of cooling and intake. The naca style openings would look better. I may need to rethink the original idea. Thanks for the suggestions.

 

For our local events nobody will give you any flack for running a NACA duct, as I assume it is for FP in RMSolo2? If you want to keep the stock cover you may be able to drop the rear of the headlight cover down. I have seen it done on FC's but would think the same could be done for a FB?
Dropping the rear of the cover down on a FC actually creates a nice little scoop for allowing more air into the engine bay, but won't guide the air to a specific point.
