Rear mount radiator
Not to make ANOTHER thread over this topic, it just seems a lot of the threads that I search are filled with concepts and ideas and no actual true tests or tips.
I am currently in the middle of a twin turbo setup on my car and really need more room than I have in the engine bay. My best idea was to move the radiator to the rear but I just wanted to see if and how others are doing this, the car IS street driven (few hours of driving to spots and racing) at a time. I'm not super familiar with any rear mount setups and no one local has anything like that so I just wanted to see if maybe someone here had done it and could share some pictures or tips on how they have it setup.

I just eliminated tge AC. Seldom does temps warrant the need for ac up here in the northwest. This freed-up enough room to run fairly wide intercooler(s) and a Dewitts rad w brushless fan. Can't say I'd do the same in the southern US however.

I did one and it worked pretty good. Hardest part is getting all the air out of the system. A scirocco sized radiator fits perfect in the rear between the frame rails. 16an front and back. I ran a single Davies Craig EWP150 water pump at the rear of the car. In the middle of the run of hoses I ran some 1in aluminum tubing in the center of the car. Idled around 160-170 degrees but crept up around 200-210 on the highway under load. Coasting would drop it back down. Never overheated during pulls. Weight distribution was nice. Something like 48 front, 52 rear.
Running the same style/size radiator front mounted now and works great.
