Z06 additional coolers on a Stingray?
Has anyone added on the additional front radiator that the Z06 has to a Stingray for the extra cooling capacity? On a track I could see how having the extra cooling could be beneficial?

Add the V09 radiator. It goes in the air intake on the drivers side. There's a thread on this. I'll be doing this mod as my oil temps get too high on track. Don't know of anyone that has added an additional front radiator. It would require significant mods I suspect.

I've read that C8s sold to the Middle East countries have an added radiator due to the extreme heat encountered in these countries. Could this be the same radiator discussed here? Anyhow, looks like there's another radiator out there that can be added to a C8,

It's the V09 option. You can buy all the GM parts on line to install. Albeit a PITA.

I used the stingray crash bar with some brackets and used the EOS center section. I first used the stingray center section and cut out the area behind the front license plate area for the duct. I just recently changed to the EOS center section.

This was the mounting, not the final bracket but close I rounded off the edges
This was the area I cut out of the stock Stingray license plate cover. I could reinstall the cover when I didn't want or need the extra cooling.
This is the EOS replacement. I got the eBay equivalent for 200.00 fit and finish were fine.
This is the aluminum hose distribution block I got from the Z06 to channel the water the correct way. As far as a write-up, I don't have one. I just ordered the parts I figured I needed and got to work. It wasn't particularly hard, but it was involved. The only issue I have now is getting up to temp when it's cold outside. In New Orleans, that means 50 degrees F. Oil and water are cool on track 210 for water around 220 for oil in the summer. I did wind up putting a thermostat in the V09 because It was a solid struggle to get oil temp when on long interstate trips with no load on the motor. 140 degrees...a little too cool. Dm me is you want the ends and out and a parts list
