Some details like active flaps in the front splitter, what appears to be wheel cooling fans, and double diffuser. https://www.youtube.com/watch?v=4BqjVplGAHA

...of options in the aft (muffled) section to get to 97dB (or less). NOTE: when in OPEN - there is still flow through the aft section - you'll see that in the video when he fires it up. Cheers - Jim I don't know where in "class" your car fits - but the aft exhaust could blow a diffuser for...

I like the rear diffuser. https://www.youtube.com/watch?v=bpX3gA40IFI

I believe that is Chris Gonzalez' old Vette.

I thought the undercar strakes were interesting considering how large and efficient the rear diffuser looks. Is it a general rule that removing as much air out from underneath is best? Even when that air can be used to generate downforce from the diffuser? These cars also have the opposite of a...

The HP numbers* suggest I should change the entire system. The biggest issue with a cut out would be the individual runners don't meet a collector before they're outside the car. I'm pretty sure I don't have the time to fabricate an exhaust before the end of May; however, next winter I may...

WTF is with that guy's voice? I made it to 21 seconds, and then I had to exit the video. Any cliffs?

If I had seen that silver car before I painted mine... that's gorgeous... maybe the next car (ha). The green C3 at Optima had basically that (without the hinge) flap screwed to its rear spoiler... I was too busy with my troubles to watch him run - but I've watched (you?) with the yarn taped all...

...nicely) on that car?? The wing is cool, I imagine it has to be at least that tall to give any notable benefit with how dirty the air is on the rear deck of these cars. The diffuser probably cleans up the airflow quite a bit considering the rear is almost a parachute without the spare tire up...

...Kyle didn't use a bit of CAD to get a more accurate frontal area. Although no good shots of the new car I guess. His notes on the diffuser are spot on I'd say - and I bet they went with the easy build (straight vanes) after all the other complex work. Sad though. Cheers - Jim FWIW - He...

Here are a couple of thoughts based on what others in the racing community are doing. A front splitter with diffuser tunnels produces good downforce. Air ducted into a narrow slot in the front fender well front lip creates a low pressure area outside of the front wheel (air curtain) for better...

Incredible workmanship and engineering!

Hey Jim, I have the tunnels/belly pan/diffuser off the car right now doing some undercarriage work, but I was able to take a couple of photos to show how the diffuser tunnels are set up. The sketch shows how the tunnels blend into a rounded leading edge that is actually an extension of the...

...and possibly more downforce. That Porsche got more downforce and brake cooling with theirs, granted it was differently designed. The dual diffuser is there, not sure if they are better, or just allow room for transmission in such a dropped car. The driving part I pretty much skipped. Oh...

I'm trying to figure out what's the purpose of some items I'm seeing there. 1) Do those small diffusers add any downforce, or are they just shaped that way to feed cooling air to the brake cooling scoop attached to the lower suspension link? 2) What does that J shaped piece do, other than...

Mfain mentioned the C8R exhaust to blow above the diffuser to aid downforce. This talks about a blown diffuser as creating boundary layer control, for an F1 this could mean above or inside the diffuser. I think the c8r is more like a jet ejector effect, but lowering pressure at the exit lip...

I'm with you on that. They do look added on but I suppose that is a byproduct of how big they are. However, it looks like a very nice build.

...me? :) The underbody strakes are a real keeper, like the tire air curtains many posts back, - as is full belly pan. Flow directing with diffusers built into splitter, some cool suction or boost in the rear deck... and on, and on, an on it goes. So many mod possibilities -- so little...

You get a good look at the rear diffuser, also the front and rear fender flares are chopped off on the back up to the wheel center height. https://www.youtube.com/watch?v=mCElwtx05pU

...areo on the M720. I sourced the following image showing the vanes and splitter on a 520 - similar underbody thinking. Note the mini-diffuser built into the splitter in front of the tires. These can be very powerful. One outfit did some downforce testing trackside and found these...
