I have to say, I’m not a fan of the way the compressor inlet tube necks down in the cross-sectional area. I’m sure there is power and response to be uncorked by installing a larger inlet. Why did Chevy choke it down? I’m guessing there are some basic rules about minimum clearance between parts. In this case, the compressor inlet tube distance from that massive oil tank for the dry sump system. The silicone tube between the turbo and intercooler is labeled on each end so there is no confusion on the orientation of the tube.
The path from the turbo to the intercooler is about as short as you can get. Chevy made it about as straight as it can be too, for minimum pressure drop and maximum response. The intercooler is a dual pass for the coolant. From this view, it becomes apparent the extra importance of the insulation over the exhaust manifold and turbine housing to minimize the heat soak into the intercooler.
You know how motorsports tech carries over into street cars? Chevy has been using port and direct injection on its Indycar engines for a long time, which has given them millions of miles of testing and calibration optimization. The port injectors can be seen on the outside of the blue intake runners and the high-pressure fuel lines going to the direct injectors inside the V. To have good drivability, power, and emissions, both port and direct injection need to be used.
The engine is stuffed in the middle of a whole lot of aluminum chassis. Massively wide Cup2 R tires still probably need all the help they can get from the traction control to not go up in smoke. Underneath the rear bodywork, you can see the robust mount to which the wing actually attaches.
Minimizing intake restriction while providing good air filtration means a massive airbox with the maximum air filter surface area that can fit.

Great article. I´ve used to them being a lot longer though.
Silicone compressor outlet hoses are sometimes used on high boost diesel engines.
E.g. VW CUAA, a 2litre biturbo diesel with 236hp and 369 lbf⋅ft from 2015.
Makes sense on the higher boost diesels. More boost, higher temps.
There’s just not as many interesting cars that the LA Auto Show as there use to be unfortunately. None of the German makes show up anymore, so no Audi, BMW, Mercedes, or Porsche.
Most car shows in recent years have been snooze fests, especially the ones in Europe, just a whole bunch of soulless, political correctness on wheels on display.
The only car show in recent years that I find even mildly interesting is the 2023 Japan Mobility Show, but it was mostly a bunch of cool looking concept cars instead of cool production cars though.
