Adding auxiliary radiator? So out of curiosity, has anyone ever looked at using the heater core circuit as a means of adding a secondary radiator (think heat exchanger sizing)?
My e85/procharger setup has an issue with heat creeping up and radiator size is somewhat limited. I'm going to try and ensure air isn't flowing around the Griffin that is in it now, but I don't think it has enough radiator capacity in it to truly control the heat the engine generates.

I assume you will have it somewhere in the air stream?

This is my next step if shrouding off my front end doesn't help much. I've spoken to a few people that have done it on a C6 vette (my chassis). They are doing it like you have stated, using the heater core outlet/inlet.
This is most likely the one I will be using: http://www.frozenboost.com/water-to-...or-p-1002.html

Yes; or if not fabbing some ducting and/or fans and remote mount it somewhere.
Nice. Do you have any feedback on how effective it was? I haven't been able to get a solid answer on how much flow comes out of those ports.

It may be easier to run extra fans I.E. two 12" pusher fans in addition to the current pullers.
I had the same issue ( some do .. some don't). I was one of the lucky ones. My 16" & 9" Spal fans couldn't keep up. I added two 12" pusher fans & problem solved.

I have a stock LS1 Fbody radiator. If I'm not mistaken I tried to fit the thicker LT1 in there but ran into issues fitting my F1A & truck hat etc.... I know others have done that and it worked but it wasn't an option for me. I was actually surprised when the pusher fans were installed & it finally cured the problem. Stays cool as a cucumber.
I think Bob mentioned that there are a few people separating their AC condenser from the equation & that lets more air flow freely.
PS: be sure that ALL of the air is out of the system. Use any method of witchcraft to remove it. That was also a problem I faced & thought for sure I was on top of it. It turns out that only after I finally got all the air out the problem lessened quite a bit but wasn't cured.

In my turbo LS9 RX-7 swap we run a 2nd small radiator out back between the fuel tank and bumper without fans and it does keep things cool..... under 190* in a 90* day racing 1/2 mile events after pulling back into the pits from a completed 195mph+ pass.

Bump this up to the top. I'm interested to see if anyone had success here. I have issues in my turbo F-body with keeping it cool while running AC. I don't remember having this much problem before the motor rebuild. Looking for cheap easy ways to keep this thing cooler.

Best way is adequate front radiator, and plenty of cold airflow through it.
But if that option is exhausted, then additional radiators are doable if you can install them somewhere and get air through them
