Pg 25 was first posts (working backwards) I saw on those diffuser ducts In Internal Body Aerodynamics Thread. There should be a bunch of older posts.

I heard one thing in this video that was new. That tire squirt vortices could upset the diffuser flow and strakes in the diffuser might help.

...in the air dam to the 4X3" brake cooling hoses that are directed at the caliper and center of the brake rotor hat. In the center is a diffuser and outlet nozzle for the small Setrab power steering cooler. Working on the front splitter/undertray with diffuser tunnels that will terminate...

...up some aero pieces. Here are all the lines for the transmission and differential coolers, followed by a photo of the upper layer of the diffuser that covers them. It will be a two layer diffuser, with the lower portion being just below the exhaust tips and extending about 3" beyond the...

...so there is damage to the underside already. I think everything was pretty symmetrical before the crash. I was curious about the rear diffuser. I think at the leading edge, just forward of the rear tires, there is a "blow-out" panel that dumps the airflow from the diffuser when the car is...

Interesting aero on the NASCAR Cup cars. Notice the splitter tunnels and the airflow out of the rear of the wheel wells. Belly pan under the motor. NACA duct, probably for cooling behind the motor. Rear diffuser.

The young guy with the beard in the first splitter vid goes into the splitter diffuser. He describes it as a Venturi effect. He keeps most of the wind tunnel data to himself. :)

Staying with the discussion of Tunnel/Diffusers on splitters. I've mentioned previously, that the added efficiency can result in using less surface area. Even though RHR keeps their wind tunnel data "close," they have let out some very useful information. Here I have used that (intel) to...

...will have 4 tunnels, two of which dump behind the front tire ahead of "barge boards" that will help direct the airflow to the outer diffuser tunnels that run inside the outer rocker panel/side skirt and outboard of the frame rail. The undertray will be Kevlar (on the bottom for scuff...

...Front wheel -- vortex and Fender Louvers Hood Fender Side Vent (Disappointing) MID-SECTION/UNDERBODY: Belly Pan, etc. REAR: Rear Wheel Diffuser Rear Flow FRONT: Great analysis on the front wheel flows. I can't tell if the flow you can see over the hood is on the hood or the fender. It...

Pappy - Looking forward to seeing those. I'm on a slightly similar path and have shaped the upper surface, and the side walls. But, alas - rain so "glassin' the lower surfaces [of a sellig 1223 section] waits. Not just Tunnels - but an homage to the Lotus 78/79. Cheers - Jim

very nice, I like that idea. I noticed the same idea in a cool down fan in my pellet grill , which has a fan on for a cool down period

...the center of the engine bay cover (looks bent) any thoughts? In the previous pic maybe so, but in the following still flat. Also note the diffuser segments are just inboard of the wheel/tire with the wheels straight. More on this later. 3. Are the wheel flow fences asymmetric? Makes some...

...of all the aero changes G-Speed made to Jake Latham's NASA ST2 champion C5, including a new undertray/splitter, full belly pan, new rear diffuser, and side mounted exhaust with explanations of their rationale for each change. It is in autocrossing/road section of the Corvette Forum...

That is a good one. Add some of the "diffuser" like sections to the area under the front valance and you'll increase the downforce, and be able to minimize the forward area. those "could be" also setup to provide a bit of aircurtain effect - but I'd have to think some more about that... To...

...bet there are some sweet ideas for underhood ventilation to fender vent if you wanted to do some Time-Attack! Right now I am focusing on Diffuser-Science this week, as the rain has set in (Florida has its days), and the rear end is the next big glass layup. Sorting curves, percent of...

...The power steering cooler is behind the air dam center opening, but again with no fan. There are temperature controlled fans on the fuel, trans, and differential coolers. The trans and diff coolers discharge air through grills above the diffuser, so they may contribute a little to aero...

...both when you make the "cut." The lower edge of the end plate looks nearly aligned (parallel) with the flying buttress trailing edge. When you get the diffuser in the mix - you'll probably want to add some front aero, and be happy for the HP you have available too. Looks nice. Cheers - Jim

...And I'm looking for a trailer that won't brealk the bank. Didn't see/hear mentioned the added efficiency you can gain from adding the diffuser/tunnel on the splitters. [Maybe missed it] These additions can add significant downforce and can help reduce overhang to limits (when needed). If...
