Just a weeeee bit more expensive though I'm thinking and not a DIY.

I plan on painting them PS and mount them with fewer rivets than the one shown...

Yea, I do remember it being a bit busy under there when you were at The Dragon.
Waiting for the after pics

Dummy tear drops? Cruiser skirts? Where're you coming from? I don't get it...

Forgot to credit...that image of the louvered Mini belongs to Canyon Mini at Motoring Underground

Not exactly your everyday lead sled with skirts and dummy tear drops eh?...
Honestly don't know how to take it.
Might just be a play on my "old fashioned" reference.
The louvers will work alright. Don't really know how they will impact the IC but your feedback will be "cool".
Sorry...... couldn't help it.

JCW ( J C Whitney ) sold bolt on louvers at one time, they still may, hood scoops, lake pipes, bullet tail lights, you name it stuff so you could build that custom ride with lots of bondo & lets not forget the heavy metal flake paint job.
About 40 years ago a shop with a louver punch was a big deal, today the old louver punch is a "what's that?". At one time I owned a 39 Chevy sedan that had a 392 hemi, 10 - 3.73 posi, Pacer front end, moded 727, 2 series D AFBs and a louvered hood. To get the louvers I had to travel about 90 miles to a shop in NY & wait a week. Maybe the louvered hood will make a come back, the only thing you needed to do was make sure that in a big rain those big 4 barrles diden't suck in gallons of water. God ,I loved that car with the louvered hood........

I did look at JCW (I actually knew what were referring to
) but all they have now are "stick-on fake louvers" to match the Folgers exhaust

Random question for the bunch, how much, if any, pressure is under the bonnet that would restrict the flow of air? Is that the point of the louvers, to minimize that pressure?

As the DFIC is injesting significantly greater amount of air as compared to stock IC, pressure under the hood will increase and any additional area of relief besides from under the body will benifit it's efficiency...

My speculation is it will be a bigger help in cooling than in pressure relief.
Just a thought though. Do you have to cut a large hole to mount these louvers? If so you could run one of those body panel shapers (edge lapping or some such) that would set it down into the hood. Less likely to lift at speed.
"Chevy with a Chrysler drive train. Gotta love that.
Running Carters too. No Holley crap for a Mopar guy eh?
"
Got to say I'm not realy, Chevy, Ford, Mopar, BMW... whatever guy & the sound from a big AFB, let alone 2 AFBs, is to die for. It's almost as good as a 671 on a big block. Had 4 911s, got to love a Porsche, still have a 66 Spitfire with lots of good stuff ( an added 80hp in the trunk, had this car since 68 ) and last but the best is a 68 TR6c bike ( and no it's not fast ).
I'll tell you what, the MCS, pound for pound, dollar spent, is one of the best overall cars I have ever owned.
Next.
Stick on louvers. What's this world comming to?
"My speculation is it will be a bigger help in cooling than in pressure relief."
It would depend which way they face ( no pressure involved ), either way they evac heat ( foward pushes heat down out the bottom with a good cool air supply to the top, back heat out the top - reality= 6 of 1, half a dozzen of the other ). They let rain, dirt, sawdust, bugs ( bees especialy ), rocks leaves....... The sure look good though...From any angle... They always look good. Boss is a better word..

Yes...definitely need the air nibbler for this job...must be fearless to do this mod
"I think this one of those things that needs no testing...just intuition

"Fearless" - being the key. I don't think there is any doubt that they will work & work well, not too sure about the looks though.
Post a couple of picks when you're done? I'de like to see the underside.

Steve,
I like your idea of making a "hood" that goes on the IC, vs a new diverter/scoop. I thought of taking the whole factory scoop off the bonnet - 4 screws, right, and then making something similar to what you have, but include the scoop. That should give you more than enough room to work. This would kinda look like the M7 extreme with it's "nose" sticking up/out, but really grab some air.
This would capture the air and force it to go into the IC. There would be no seal issues and you could still remove it from the IC. You could also extend the front lip, like Gandini did. I am going to try and make some time and construct something out of Aluminum sheet soon. Work and school is my life, but have looked a lot at the stock setup and combined a lot of thoughts. Budget has constrained buying an after market solutuion - ie DFIC, Alta, etc.
Everyone working together has yielded much progress - keep it up!

If you install your model, can you make photos like the ones I made, with a "see though" bonnet so we can actually see how the scoop fits relative to the bonnet and IC? If you need help with Photoshop, PM me and we can work together to get the photos done, all you need is a digital camera and tripod.

Took a different path but the same concept. Aesthetically I don 't like stuff hiding an IC I paid good money for
My first attempt at working with fiberglass so forgive the ugliness.
I can already see where I can improve it but here goes:

Didn't get a good pic of it but the clearance over the top of the on IC diverter is probably double what it was on the high side(the bulge in the center of the hood) and 3/8th higher on the low side.
