Which Radiator?

Which Radiator?
I'm going to be upgrading the radiator and going with Evan's NPG as we wrap up my PTK kit turbo motor. It will be running about 700HP to the wheels and will be daily driven. While everything is out, I want to upgrade the radiator. What would be the best model to go with (I have an A4)? Below are the two that I've come up with so far:

Are there any others I should consider?

Check out AFCO radiators, much cheaper. Our radiators are 27 1/2 x 19 inches I believe. There are several GM styles that would work.

Re: Which Radiator?
Personally, I would recommend the stock radiator/fans and coolant.
That's what I use, and my car stays at 180 whether it's in traffic, or WOT for a mile.
My experience with evans NPG is long warm up times (due to no thermostat), and eventually high coolant temps, which would be okay (as you aren't going to boil the coolant), but it can bring oil temps out of control without a cooler.

Re: Which Radiator?
I do still have AC, and I also have an auto trans with a huge cooler. I am not comfortable with the temps I was getting with my relatively stock engine, and would really worry with an engine like this in stop-and-go traffic that I have to deal with daily.
I'm banking on the Evans based off of some extensive research of some board members here. I know it will show a higher temp at the gauge because it's pulling more heat, and am ready for that. If I am wrong, at least my very expensive mistake can help deter others later.

I was looking at this radiator because of the built in heat exchanger for the oil. Anybody have any opinions on the validity it being better to have the oil and coolant having closer temps to each other?

Re: Which Radiator?
I went with a "be-cool" from Summit (for an M6 manual). It has all the stock hook-ups (low coolant + oil cooler hook-up). The With good air flow (30+mph), temps are steady @ 170*f. But in stop and go, the temp can climb to 210 in 80*F weather with the ATI-D1 & intercooler. Also I have dual 12" 1200cfm flex-lite fans that run constant. I went with a Summit air-to-air oil cooler (trashed the slp). It dropped temps.

With my heads/cam car and my becool radiator, even in stop and go with the a/c on high in the south florida heat, my coolant temp never goes over 180 (on my scanmaster, not the pos gauge).

Re: Which Radiator?
When i drive my car the temps keep going up. no fast really, but over 30 mins its at 210 around town, thats when i usually call it quits and go back home.
Sucks only being able to drive 30-40 mins at a time.
Now on a freeway its fine, night its better.
But racin, after 2 1 mile laps on a road course the coolant is boiling.
sighhh. The problem needs to be resolved, but friends with be cools and griffin have the same problems.
