I have experience with a 2 core aluminum radiator on a ~350+ whp turbocharged app. With a set of FAL fans on there we typically ran at 170-190 degrees on the freeway, 190-200 in traffic.

And that's with a no name radiator. A Fluidyne would do a much better job.

Chances are Fluidyne makes a radiator for your car. In fact, I would be suprised if they did not.
