I had similar issues with another car that I used W2A IC on it, I have found that when you go for a bigger radiator/HE combo, the more capacity you need for the reservoir, or you will end up with air pockets that will eventually cause higher temps.

83F ambient today (not a typo, stupid Texas weather)

Start up and see 87F from cold to fully warm with occasional dropping to 86F.

That is 3-4 over ambient at cruise. Nice!

I was consistently seeing 20F before over ambient at cruise, so I think I have gotten more water into the system by rerouting the remote fill cap (although I know its still not 100% full).

Then I do my favorite pull. Drop to 3rd at around 68-70 MPH and hold it to redline.

I see a peak of 106F. That's a rise of 19F over cruise inlet temps and 23F over ambient.

So, from this latest data, I am seeing good cruise inlet temps over ambient, but under 1.4 of boost is still higher than the A2A.

But the caveats are still twofold:

1. No cooling fan(s) on the heat exchanger
2. No idea how full the system is

I am pondering putting a long, skinny rectangular tank (say maybe a gallon or more) in between the shock towers in the rear so the water level will not be a factor. The pump will constantly have water on the inlet side.

To add a fan I have not decided how yet. Real estate is so limited and making an offset sheetmetal shroud is some figuring.

The system works pretty good as it is so I have not been in a hurry to work out all the improvements.
