Airflow through the Z's engine bay is pretty crappy. If you already have track spec vents an additional two holes on top of the existing opening will allow a lot more additional air in onto the radiator. I never did it personally but it helped with other boosted 370s.

After my turbo install I hit 240 before popping the cap release. But I don't think the CFS radiator is any better then OEM, it might even be worse because it's prone to leaking.
