When one radiator isn't enough, then use two. And if you can't buy it, then make it. Or at least modify it. This is the dual radiator system I installed in July 2011. The radiator on the left started out as a custom crossflow from Griffin Radiators. The only output I had them put in the tanks is the air bleed (lower left of the radiator, which is actually the upper right when the radiator is installed). Since I wasn't sure myself where the inlet and outlets were going, I had to wait until I mocked everyting up with both radiators to figure it out. After doing some extensive cutting of sheet metal up front to make the radiator fit, I welded on the mounts and the inlet and outlet. The radiator on the right started out as an 18"x 22"x 2"radiator I purchased new off Ebay. I then proceded to band saw it into a 7"x 22"x 2" radiator and weld up the tanks. It gets tucked up in front of the passenger side front wheel, behind the head light (see below). Notice you don't see any fill point. It ended up having to be remote, very remote! Here is how it all works. Water from the block enters the primary radiator at the port in the picture that is perpendicular to the ground (which is actually the top of the radiator). It exits from the port diagonally across from the entry point and gets connected to the long tube on the secondary radiator. This feeds that water into the top of the secondary radiator which then exits again diagonally at the bottom of the secondary radiator. The port is connected to the water pump and the cycle starts all over again. The tube that long tube "T's" into is the fill tube. All together this system has proven to be absolutley awesome. I have not yet seen the temperature get over 185F, even on the race track.
