Hey everyone,I think I know the answer to this already but I have a question regarding how effective (or not effective) this diffuser design is. Just asking for the sake or learning more if I ever design my own.

I'm working on second design that will feature a curved profile instead of flat. It will help the air stay attached to the diffuser surface at more severe angles. Also the angle on the diffuser in the pictures is adjustable. You can run it right up to the bumper if you wanted to. |

Had some time to work on a new front end for the race car. All removed with 4 bolts at the front. Will get a picture with the bumper attached. Its nice to have all of the ducting attached to the undertray instead of the car. so much easier to work on.

Love the idea and implementation, my concern whenever I consider this type of setup is removing the front tie bar across the front of the chassis...would be so nice to have it all on the undertray as you say!
Are there no issues with chassis or overall strength when removing that bar? put to OP and others.... |
Also, Emilio I thought that you were one of the defenders of not bothering to cut out rear bumpers, I could be mistaken or is this no longer the case?

Do you have a build thread anywhere? That car looks very well put together and I would like to grok it.

I too haven't had any issues with that cross section removed. I have a small 1" square tube welded in between the two sides, so not quite as drastic as having nothing spanning that gap, but that tube is mostly there just to support the front of the intercooler, not so much for the chassis.

Isn't anything in front of the crossmember "just" for crash protection and support for body panels etc.
But with an improved (flimsy) crossmember you might need help with stability from the framerails. Having stock structures helps when bouncing against guardrails... |
When designing an air damn the air intake has a certain size that is an optimal combo of drag vs air intake right? Does this change when adding a grill? When adding a mesh grill do you take the area of the bits blocked by the gril into account?
Just thinking. No actual reason behind the question, thought this would be a good place to ask. |

Grill and mesh choice
We typically make grills from three meshes of different open ratio. Basically cool and hot weather. With a reroute, it's easy to overcool the engine to the point that the oil doesn't get hot enough. The more closed it ism the less aero drag and more downforce on the front end. Wire mesh from mcmaster.com 9217T41 81.5% open area hot weather (pictured) 9641T241 61.6% open area warm weather 9227T632 44.8% open area cold weather, what we ran at T25. https://www.miataturbo.net/attachmen...ine=1330659533 |
I've read that. But should the opening stay the same?
|
If you're calculating the "ideal" opening size, then block some of it again with mesh, I'd think you'd need a bigger starting opening to get the same amount of air through.

I run 1/2"galv. farmers cloth, also known as construction cloth, picture above. On cold mornings I just add duct tape till it warms up in the afternoon. To answer your question I don't think the 1/2" effects the issue enough to figure it as being in the equation. Going to the 1/4" or 1/8" would be a different story.You can buy this stuff at any local hdwre store usally by the foot.

My answer to a question no one has asked; EZ on-off splitter, steetable track car. Basically I don't wanna have to buy a trailer so...The 4 front elements nest together and fit on the parcel shelf for transport to and from the track.
https://www.miataturbo.net/attachmen...ine=1452227713 4 Removable front elements https://www.miataturbo.net/attachmen...ine=1452227713 Front elements mounted https://www.miataturbo.net/attachmen...ine=1452227713 This section remains on the car and serves as the mount for the removable front elements |
