    That is an aero problem. That great big, and highly efficient nine lives wing created a ton of low pressure above the deck which drew very hot exhaust gases up the back of the car. The modified exhaust and tune contributed some by creating a hotter than normal exhaust plume, but the aero is the...

    Internal Body Aerodynamics

    Yes, the rear calipers are on the rear on a Gen V Viper. But, they are on the front in the C8 Z06.

    A little. it was pretty famous for a number of years at Elkhart Lake/Road America. There were three built almost alike - numbers 23. 24, and 25. I have talked to the owner of number 24 several times. The owner of this car passed away a couple of years ago. The car is pretty cool. I am...

    EXTERNAL AERODYNAMICS

    Thanks Jim. It is Kevlar on bottom for scrape resistance, foam core, and carbon fiber on top. Should be plenty strong. Yes, the splitter extension is removable. It can be replaced with any extension made for the Viper ACR. I have 3 different widths and materials, and I am building another...

    EXTERNAL AERODYNAMICS

    Finally finished the front undertray for my C-1 track car. Bought some rubber strakes for a '23 Corvette Z06/Z07 and cut them up to help guide air to a couple of the diffuser tunnels. The front tunnels empty outside of barge boards that guide the air toward the outboard side pod diffuser...

    EXTERNAL AERODYNAMICS

    Now that we are on the subject, here is an experiment I intend to conduct. I have already built diffuser tunnels between the frame and rocker panels/side skirts. Air is fed to them via the front fender splash panel behind the tire and barge boards along the frame. I built CF plugs for my...

    EXTERNAL AERODYNAMICS

    This may be a little hard to explain, but here is what I would suggest. Add brackets to the frame behind the front fascia to support the splitter, Then attach the air dam (really a filler panel in this case) to the bottom of the spoiler but do not attach it to the splitter as a supporting...

    EXTERNAL AERODYNAMICS

    The CF splitter extension (from Doug Shelby) is honeycomb core. The black one with the red edge is a solid, harder composite plastic of some type - durable but much heavier. The stock Viper ACR splitter extensions are also the harder composite. The new one I am building is foam core with...
