Cooling for diff I'm working on. Flex hose fits onto the NACA duct and then slips over the cooler.
Hoses go straight down to the diff and into the Greddy High Capacity Rear Differential Cover, ZN6 14510400.

%-17-2025 I ran at Club Motorsports and even with heat-cycled out Hoosiers I got within a second of my best ever lap time. Was very pleased, especially when the car still lacks a tune.
I ran my new side skirts. Soon to be lower and black.
Diffuser is still in the works. I've just had trouble finding someone who can roll the parabolic shape since the part is four feet wide.

First trial fit of the diffuser I designed. Three strakes still to attach. Holes are for a rod to keep all six strakes in alignment. Muffler is above the diffuser in the middle. I built the 2.5" custom exhaust to fit in the tunnel and above the pan and diffuser.
Lots of challenges to accomplish this and manage exhaust heat.
Plan is to be ready for Watkins Glen June 29th.

Center exit exhaust. Muffler so I can run at Club Motorsports. No muffler required at The Glen.
Exhaust relocation so there is nothing to impede airflow through the new diffuser. Name: Muffler hanging.jpg
