Rear Diffuser on CB

[CB7Nub]

Has anyone hear of one made for a CB? Probably not, but I would die to have one. Imagine the look of a carbon fiber rear diffuser on the rear of a clean CB.

Old school buddyclub rear bumper.

there was someone on this forum building one. but he didn't finish. or really get started the only one that i've seen that "looked" like a working defuser was the older buddyclub bumper covers.

you can have one custom made to your cb by SOME CF making companies, but it will definitely cost you some money..

make your own, goto home depot and make one out metal sheets like this guy

not as pretty, but it's a "Start"

Interesting. I wonder if someone has done the math to figure out how strong the materials have to be for that thing to be effective. Cool Idea though.

When I get another cb Thats one of the things I wanted to do.... One off diffusser. Just like the one from nasioc.... Seen that one almost a year ago when I was helping my friend with his 04' Subie.

Ya, the civic I can't see that working especially if its sheet metal you can cut with scissors. But the fiberglass one looked really professional.

Ok, so after reading this I really want to do a rear diffuser that actually serves some purpose. I've done some research and found that leaving the exhaust open like the one on NASIOC will create turbulence and, therefore, not be (as) effective. From what I can gather the exhaust would have to be above the diffuser, like this:



From what little I've looked at under the rear of our cars something like this would be possible:



But then It'd have to run an awkward exhaust.

Also after some more reading, in order for the diffuser to work properly the car has to be rather low to the ground. I'm not sure on the specifics as to why, though. I guess it has something to do with the dispersion of the air pressure , but that is merely my uneducated guess.

Of course it will just look cool to do this as well, but I'd rather not add senseless things like that to my car. As I'm sure this will take many hours to fit properly.

Anyways, input, advice, criticism is welcomed

found this i believe it was taken from a bodykit and molded to the stock bumper looks good tho imo.

Yeah, what I'm talking about is more than just looks though. I'm not expecting 700 pounds of down force or anything from it, but I would like for it to be functional to some extent.

Adding anything like this is only adding weight...you have no idea what its making the air actually do. You need CFD...
