Itis! you opened a can of information worms here with this aluminum rad thing.
Sounds like you have a huge menu to think through and it is COOL that some heads of state on here have/are already trying these various rads in real world street conditions.
I'd be confused.
Does a blown motor create more inner heat than a conventional motor?
I have an AFCO unit in mine for years and it seems to be on the edge of efficiency for my ride at least, so double check your options. IIRC the Afco brand is what the boys and girls use in stock car racing. Lots of heat, but also lots of wind speed if you're not tailing. If you're tailing in that scene, then that rad has to be a good unit.
As a side note, I also made sure to design and make a tight lip air ram system in front of the car utilizing aluminum sheet to create walls where all the incoming air can not go anywhere but through the core of the radiator.
You have time, so take your time and research.
