The extreme AreoCRX-HF project

[MetroMPG]

Congrats on the find!

Phil Knox (aerohead here) extensively aeromodded his CRX just like this one. You could do worse than to use it as an example. His work was estimated by a 3rd party at Cd .23 when he was finished:

I think i just came up with a neat thing I can do since my CRX has a carb.. some how make a sensor that lets me know when i open the secondary butterfly in the carb... or a way totally eliminate the secondary from operation.. like a electronic lock to keep you out of the secondary that you can disengage via a switch if you need it... However this will happen after the areo mods.

Ill also be running a vacuum gauge inside for monitoring too.

UPS dropped of my new carb plate, and I installed it and its running absolutely perfect!!!

And i didn't mess anything up with all those vacuum lines etc.. that was my worst fear id screw them up and be cratching my head a while..

Anyway this means I can start on the body mods now.. Let the fun begin!!

Sweet! Looking forward to pictures of the progress.

Progress moving along quickly!!

First i used some PEX tubing to make some frame work for the body work, pex makes nice rounded corners easily and is lightweight and flexible.. Below are some photos of the framework.



Next I got some cheap fleece, fabric.. its soft and pours and stretchable in any direction.. The fleice was stretched over the frame work and then fiberglass resin applied to it as you apply resin to the fleece you need to keep it taught.. after drying you have a nice light weight shell..
Here are some photos half way through the progress, i worked my way from the top down ding parts at a time and letting the resin set and lock into the PEX framework..




So for materials used for this front will be 1.5 gallons of fiberglass resin, 4 yards of fleece and 40 feet of pex tubing and 5 eyelet bolts (this is what I used to attack the PEX to the radiator support on the car) and 8 screws to screw PEX to the plastic bumper cover

Yeah I'm surpriser how quickly this is coming along.. Ill have the entire front end upper shell done today, then ill let it cure fully and cut the holes for the lights and then start adding foam and shaping it better.

Ill also be re-enforceing the bond between he PEX and the resen'd fleece from he under side with a layer of fleece and resin to ensure it can handle some rough treatment.. once thats done ill be able to cover the bottom up.

Do you have any Cd goals?

[ebacherville]

well the entire thing is done minus the bottom once it cures ill beabl3 to tackle the bottom.. ill need to make some braces for the underside.

Ill get some more photos tomorrow

Not really, I would not know how to get a good estimate of that anyhow.. however i want improvements logically ..

My main goal I want to boost MPG to above 80mpg .. preferably 100mpg... however there is a point that you get deminishing returns.. aerodynamics is a easy huge gain thats well worth the effort, so far this nose is about 4 hours of work.
