Some time back in one of the road race bodies (can't remember which) guys were dumping the exhaust into/under the diffuser with some success. It got outlawed because when you let off the throttle you change the exhaust pressure and ultimately the downforce which resulted in loss of control in...

Nice work. That’s going to be an interesting car.

...am dealing with the same "potential" with a 515 inch big block in my C-1. I went with a wide, double pass Ron Davis radiator. Then I built diffuser duct work from the grill opening to the face of the radiator. This duct work smoothly increases the cross-sectional area as it approaches the...

...of development happen in Japan for a number of "time-trialers." Many of his "vectored" ideas have worked over into World Rally Competition, diffusers, flares, etc. I recall he also provided aero consulting to JDM for aftermarket wings, etc. He has proven worthy of his last name. Cheers -...

...The new headers (built by a pro) will be stainless 2.25 inch tubes into merge collectors and a 3.5 inch X-pipe. BTW, did anybody notice the "up-angled" tail pipe exits on the C 8R? Looks like they are doing that to create a low pressure area above the diffuser to help its efficiency.

...when I start working the 'glass efforts. For example, I may trial either the "fingers" shown a few pages back to make an air curtain, or diffusers incorporated like this: and: For now the hood just has a HUGE gaping "hole" to dump air - pending testing: You can see the engine bay is...

Okay, more aero stuff. On my 56 I built carbon fiber "tunnels" - actually long diffuser tunnels - between the frame rails and the outer rocker panel. They start with a rounded fender well close-out fairing which blends into the tunnel. (note, there are a couple of pieces not installed in...

You also need to account for the velocity of the inlet air. Here is an inlet diffuser I helped design and my son built for a 300 mph Bonneville Salt Flat car. We were able to shrink the inlet down even smaller (2 inches vertical) to get 22% of the radiator surface area. This reduced drag and...

...pretty well. Have you noticed that sometimes a NASCAR car runs faster with the tail panel knocked off? NASCAR won't yet let them have a diffuser that runs from the fuel cell to the bottom of the rear panel to clean up the "parachute" that the hanging rear panel creates. Also NASCAR...

...from the wheel well - a good idea. But you could use the rear deck and a bit of aero-"worK" above it. Then plumb/weld/etc your exhaust through those (or other) vent to fill and provide downforce. I'll go dig up a few F1 ideas on "Blown Exhaust" diffusers, that are running around. Cheers...

...task: You'd have to add material to the side rails to be level wth the rear cross member. But you gain the opportunity then to include a diffuser in the rear! Not a 'vette, but you get the idea: [NOTE they are exhausting the Radiator to the underside of the vehicle] If you want to build...

...the vent. BTW, the duct work for the oil cooler starts with air taken from above the radiator (hard to do on a C-3) and runs through a diffuser of sorts to expand the volume prior to the cooler, and then "nozzle" duct work to the fender vent exit. This is the P-51 "Meredith Effect" that...

Hey Kid, It is a 2016 Viper ACR with the extreme aero package. 645 HP, big Brembo CCBs, and a big wing/splitter/diffuser. It has an even bigger splitter extension and vertical diffuser extensions that are not installed in these photos - not enough ground clearance for street driving. I...

I had the motor out of my 62 a while back to do some engine bay clean-up, and decided I would finish the carbon fiber grill-to-radiator duct/diffuser that I started last year. The purpose is to keep the airflow more laminar for engine cooling improvement (just in case a bigger motor ends up...

...in the upper right is one of the brake cooling inlets inside the grill of my 56. The last picture is my brothers 51 Jag (with C6 suspension and a stout, injected LS) for which I am getting ready to build a complete carbon fiber duct/diffuser from the grill opening to the radiator. Pappy Pappy
