I think that's about the worst place for the exhaust outlet though.

WTB exhaust blown diffuser.

What do you guys think of wing mounting locations? I have two different designs I am working on, a trunk mount and bumper mount. I personally like a bumper mount because it has more positive in my opinion. Let me know what you guys think...

Trunk Mount:

Bumper Mount:

Bumper mount would be tricky if the customer has put on a new body kit with different angles. All of the trunks that I've seen have used the same OEM angles.

Personally I think the bumper mount would work better with aero but trunk mount looks better and usability of the trunk is not compromised.

racecar engineering or race tech did an aero feature on this (in a tunnel) and putting the exhaust there took all the downforce out of the center section of the diffuser and even compromised the outer two sections...

they moved the exhaust to above the diffuser exiting right of the plate/tag sealled the hole in the diffuser and picked up 20 points of down for one of drag iirc

the elise/exige also have flat floors infront of the diffuser Not our "86's"

working on it.

I am not a vendor/manufacturer/ect. Just a guy who likes to make stuff out of carbon fiber.

I don't know about that elise. When I see that exhaust, I expect to see this.

LOL. Not a fan of the exhaust on that car either. But I really like that diffuser. A lot of cars run the exhaust above the diffuser and I think it looks pretty clean.

Did we ever reach a consensus as to if the Borla diffuser was functional or not?

wootwoot · 02-20-2013, 01:11 PM

And I doubt it.

You can link to an individual post that way we don't have to look at a bunch of picturers of ricer LEDs.

And no, I can't see that doing much of anything. You can't even call it a diffuser.

The Rocket Bunny piece being called a diffuser is a bit of a misnomer. It's more of a rear valance.

sw20kosh · 02-20-2013, 02:29 PM

Thats mainly a cosmetic piece. To be more functional it needs to extend further towards the axle. Its better than nothing there i guess. Looks good though.
