Right from Katech in this link. The key thing to note is both out board supercharger radiators also have another set of radiators directly behind them for engine cooling. All four radiators are identical.

So looks like this pic is then accurate. Very good info Ken!

Yup....the low temperature rads are the "supercharger" rads.

It's interesting to note that all four aux rads in the outboard modules are identical but the rear engine cooling ones are twice the price for the same part. This was discovered/discussed on the Corvette Forum.

These supercharger aux rads are a bargain at approx $140 each. (#84484399) grate #84412408

The Improved Racing MHX-520 would be a good candidate as well but are more than twice the price.

The C6 ZR1 center dual pass radiators can be picked up used for $70 each currently.

Here is what they look like.

Here is my C6 ZR1 supercharger radiator. These are plentiful on the Corvette Forum. There are two of them currently being sold for $70 each.

I have started to collect the various fittings for them. The only issue with this approach is the fittings are 5/8" and not 3/4". For max effort a true 3/4" is more desirable.

I had trouble finding all the part numbers on the GM site so concluded the rads In the cheeks were not doubled up and were plumbed like the ZL1. The Mishimoto Intercooler rads I bought were actually pretty reasonable, after discount were like $330 for the pair. Your diagram will come in handy if I do 4 intercoolers, the rear two with fans and the front two in the cheeks.
