Only marginally effective. It's a 'better than nothing' approach. So much pressure loss before it gets to the rotor. The current C7 stingray corvette has the same thing, we're removing it all and replacing with proper brake ducts for a customer who can't get his brake temps under control with those.

here is a link to a 3D model I made of the converter part. I haven't taken final measurements and angles yet as the duct needs trimming on my car.



Took me longer to figure out how to post the image than to model the thing. This should print pretty easily in one piece. Probably a 4 hour print.

That's really awesome. I would love a pair.

Not sure why I said "link to the 3D Model" in my post, I meant link to the 3D renders. Anyway this part needs some test fitting first so I'll do all that on my car, make sure it fits then I'll give everyone a link to the final 3D model.

My car is a 1989 Eunos Roadster which I think is the 'R package' lip. I'm not sure if there were changes or not in later models. I can make a CAD cross section to test fitment anyway.

I have the GV lip, if you post up the CAD files I can try and modify it to fit the GV lip.

Are you designing them to have a 3'' outlet or 2.5''?

I can easily scale the end connection to whatever OD is required. I think mine is actually a 3" duct but I might drop it to 2.5" for the final one as I don't need massive cooling.

I'm actually printing it a test piece now... should be done in a few hours.

aidandj, if you can send me a photo square on to the back of the duct with a tape measure held up in line with the edge, I can quickly model a version that should fit. I'll actually also need a bottom up shot as well that is square to the body so I can see the angle it comes off the bumper. Maybe give me overall height and width measurements too, preferably in mm!

Bitch and a half to get a good picture. Heres an album with a bunch of pictures and an attempt at a dimension. The inlets are kind of a weird shape.

That will do. It would be easier if you jacked up the front a bit higher! There is one good profile pic I can use, but the entrance flares a bit so might be a bit tricky to get it right from photos alone. It looks like it comes out of the bumper in the right direction so it would be a matter of just converting to the circular output.

What size output do you want? 2.5 or 3"?

If its not too much then one of each. Still not sure what I am going to run, and I know some of the local guys might want a set of them.

both will be easy enough... The hard part will be getting it to sit over the radius flare nicely. Have you got access to a printer? I'll just have to guess model it, send you the 3D and you can feed back where it hits, maybe even tweak the 3D file at your end if you have a 3D package.

Yeah, I have a printer at work and solidworks. I play around with it some but I'm mostly an EE guy. I can print as much as I want though.

Modelled quickly over lunch. Pretty hard to see where it has to clear the bumper mount point.

here is what I got:

Here is a download for the 3D Model (in 3ds format) GV_Brake_Duct_3inch.3ds

When printing it, you may need to add some supports to where the cutout are on the model.
