I can see why the ZR1 ran into issues, but that is a killer diffuer/belly pan setup. I wonder if adding some naca ducts would allow just a little cooling air to enter and maybe add some mesh grills like red Optima car above did. Let a little air in/out without overly disturbing the bellypan/diffuser functionality.
So the red Optima Z06 has full belly pan with diffuser and mesh screen in the back AND had burning carpet issues? Just trying to keep the cars/mods/issues straight lol
As of now there is:
Red Z06 Optima car. Full belly pan+diffuser. Burn carpet? Wrapped exhaust?
ZR1 car with high HP and burnt carpet
Tan/black stripe Z06 with diffuser/burnt carpet/wrapped exhaust/sectioned out trunk.

Only 2 cars were being explained. Hopefully this offers some clarity.
Red ZR1 (Optima Car)
700+ hp
Full belly pan
Mesh above rear diffuser
Full wrap exhaust
*burnt carpet in hatch didn't happen until hp was turned up
Z06
660hp
Full race rear diffuser w/o belly pan
No wrap on exhaust
*burnt carpet like the ZR1

^^^Great photos rbz06! Thanks you for sharing.The setup looks great! Where on the chasis are you attaching to at the seam of the front splitter and the belly pan section you made?

The the front edge of the belly pan has a piece of 3/4" square aluminum tubing, used as a spacer, pop riveted (4 rivets) to it. This makes it level with the bottom of the support below the radiator. I put 5 riv-nuts in that support to attach the front edge of the pan, The attaching bolts go through the tubing to the frame.
Yeah, the guys who did Jeremy's diffuser did an amazing job! The one issue that he ran into is heat being trapped above the diff. The trunk pan got hot enough to burn the carpet on his car. Keep in mind his entire exhaust was wrapped. I think having everything sealed off above the diffuser would not be ideal. There still needs to be some airflow up there to allow the diff and exhaust heat to exit.
You're correct! There needs to be a little relief to allow trapped heat and gases to escape. Ours has 3/4 inch venting above it.
No heat problems.

Looks fantastic!
The only car I have ever driven with a diffuser is my ACR-E and it sticks fairly well. That said my Corvette was just as quick without any decent aero and now with the new build I expect it to be quicker than my ACR-E. I can only imagine how quick the C6Z will be with proper, functional aero.
Were you able to get before and after lap time comparisons?
Nice!! After seeing yours I really want one!! Your car looks great in your signature!!
What tracks do you frequently go to? Any higher speed corners over say 110 mph where you have seen a measurable improvement? Any lap times from those tracks?
My example I use for myself is Watkins Glen only because I know it fairly well. I am not very fast compared to the fast guys but the track gives me a nice personal baseline for fast corners. I am 122 mph in T2 and 132 mph in T3 currently and would love to be able to roll T2 in the high 120's and T3 at almost 140 mph. Corey Friedman rolls T2 at 134 mph and midway thru T3 at 140 mph on the nose. lol!!
Seems so crazy to me from where I sit now on the outside of fast looking in. The car would definitely need to feel more stable like you describe for me to even start thinking about doing that. Utilizing proper aero comparable to what your car looks to have is the only way I envision myself achieving the speeds I want to in fast corners. I lack the skill as a driver to get as fast as I want to be without it.
