EDIT - Seems many folks don't understand what they're looking at. The carbon fiber cover under the main intake plenum is the access panel for the ITBs (Individual Throttle Bodies). The red part you can barely see is the valve cover. Yes this is a DOHC motor.
EDIT 2 - The yellow rectangle is the valve cover.

See that tiny little plastic pipe that is obviously not carbon fiber in the intake tract? Do you know why that is there? It's there so the other makes have a chance in a race with a C8 Corvette!

It's called BOP... it's pretty much standard practice in any/all race series. The days of "run what ya brung" are long gone when MFG $$$ are needed to sustain a series.

IMSA fans can be so frustrating. So much complaining about BOP. Without BOP we'd get unchecked spending, with one constructor winning every race, and the others leaving or just throwing in the towel. It would be crazy boring, if it could even stick around.

Even with BOP things are looking poor right now... very few entrants in the Pro Class. Might as well combine Pro and GTD.

Looks like one intake with a 60mm restrictor instead of two intakes with a 27mm restrictor in each.
Last year at Daytona (which has its own BoP) it was two at 30.6 mm
I know it's part of the restictions/BoP but I find it amusing that you can put a 103mm throttle body on your LT engine and ASO/IMSA has a 44mm intake restriction. I think they should let manufacturers put out as much horsepower and torque as you can because you pay for it by the reduction in mileage. Just let manufacturers find their own sweet spot. And, I do realize the fastest LMP cars are hybrids.

Can not wait for Daytona, three weeks. It looks like the bodyside vents are dedicated to engine and brake cooling, and the rear intake is for ram air intake, and trans/diffy, but hard to tell.
Well thats interesting. There's no window into the engine compartment from the driver side. So the window on the the rear hatch is really just black plastic. Cant see through it
And it looks like that was the case for the C7R too. Never realized that
