What are you guys running for a radiator? Particularly you guys that road race or time attack. The rad in my Lebaron is only a few years old, but it won't cool enough on mountain runs. Twisties and light grades it's not bad, but long 3rd and 4th gear pulls up steep grades causes the temp to jump up quick, even on only 9-10 psi. Are there any dual core factory rads that might work, like from a Dynasty or something? Or am I just gonna have to get an aluminum rad? T-stat doesn't seem to matter either, does it with either a 180 or a 192. In fact with a 180 it would normally run 175 on the temp. Maybe there's too much bypass through the heater core?
