  • Engine air intake flow

    I am not sure I understand how the air gets in the engine. Must flow in at least one of the large side scoops.
    Appears the Z51 has a cooler/radiator looking assembly on the passenger side.
    Is there then a duct of some type to get it in the throttle body at the mid back of the car?

    <Based on the cutaway photos and various comments, it looks like the air gets into the engine via the rear passenger wheel well. > Please ignore! much more accurate information below!

      In one of the Carlisle videos, Tadge said the upper 1/3 of each side scoop feeds air into the engine.

        This cut-away image shows the airbox feeding from the passenger side, but it may in fact feed from both the driver and passenger sides (depending on how much of the air box has been cut-away).

          It would be cool if air comes in both sides, maybe along the yellow lines.

            It does. As gearhead stated Tadge mentioned this at Carlisle stating the upper 1/3 of the side scoops feed the engine intake.

              Air intake in driver's side scoop. It's the smaller plastic duct at the top in front of the fan.

              And here's the passenger side scoop air intake duct on the upper left:

              In this photo you can (sort of) see the ductwork that routes the intake air over the wheel well and then centrally to the airbox:

                Neat. Pretty nifty they set it up to both sides feed the intake.

                    At Carlisle, Tadge said this intake is much less restrictive AND provides cooler air than they could do in FE cars. In the FE, they either had to route the intake over the radiator, which heated the air, or have a sharp bend to get the intake out to the side where there was cool air. The curves in the ME intake are much more gradual.

                      Another interesting bit of information is how with the rear trunk GM figured out how to evacuate the air out of the engine bay.

                      the large vents out back and of course the rear window design is seriously thought out.

                      when not moving or in traffic the hot air escapes via the openings surrounding the rear window.

                      that pretty cool engineering.

                        I cannot see anything in the photos as duel airmass flow paths into 1 throttlebody
                        That would end up requiring 2 air-cleaners, air boxes and I do not see room for a second filter.

                        Problem happen when 2 opposing flows crash and causes turbulence which confuses the Mass AirFlow (MAF) and reports the air mass incorrectly
                        causing AFR issues by the PCM.

                          Teamzr1, refer to Mobius's pic. The real car will have intake from both sides to air box, mirroring the right in that "show car" pic. Left side ducting is missing in the cutaway pix. That is my understanding from Tadge's comments on it.

                            Any photos I have seen has no signs of airbridges to both sides
                            I can see that would be needed when dual turbos exist

                              Both sides feed the central airbox. This photo is of the LT7 but it's the same for the LT2:
