  • Inconel Exhaust Manifold on the ME Zora?

    The ME Zora ultimately will have some major horsepower in the future! The ZR1 LT5 engine pushes almost a kilogram of super-heated gas through the exhaust pipes every second at full power. The temperature and pressure of the exhaust are actually enough to inflate sections of the ZR1 exhaust pipe like a water balloon under extensive track testing. Team Corvette had to upgrade the steel in the system and redesign sections to cope with those stresses. Shields had to be added in strategic locations to insulate things like electrical connectors and half-shaft boots from the extreme temperatures. Usually exhaust systems on high horsepower cars use Inconel as the go to metal which is a austenitic nickel-chromium-based superalloy. It's used in the aerospace industry and many high heat applications which would include mid engined exhaust manifolds. Ferrari is using this alloy for their new 488 Pista exhaust system. Hopefully the Zora will utilize this tech. See at 1:13 of video.

    From Wikipedia
    Inconel alloys are oxidation-corrosion-resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation hardening, depending on the alloy.

    It probably makes sense to use this superalloy for the mid engined exhaust manifold since it is also has twin turbochargers like the Pista! The 488GTB exhaust manifold also appear to be 3D printed or at least could be precision cast.

    Thank you Skank. I learned a lot by reading your thread. Lots of super exciting developments in the automotive field. Can not wait to see which of them are on the different mid engine models — for we all know that while many will be on the entry ME, some will be only be needed on the beastier versions coming year 2+.

      This is great Skank, thank you! Based on the leaked CAD drawings it looks like you might be on to something, based solely on the look of the headers on here:

        And look at those 4 magnetorheological engine mounts. Two under the engine and two under the transaxle DCT
