Which radiator to choose?
#21
I second this... I understand when Mishimoto radiators used to be cheaper than Koyo or CSF, but now that they're the same price, or even more in some cases (I guess all that drifting sponsorship worked), whats the point in buying a subpar product? Just get the Koyo or CSF... or Mr. Sideways if you have boost.
It's interesting that Koyo still makes a 52 mm core for the Miata while they only offer a 36 for the S2000 now.

I think a lot of people would like that cold air intake. If there was a way to work that with enough cooling capacity for a 600-800hp turbo that would be a really big deal since most of those cars seem to have the air intake behind the radiator, oil cooler, AC condenser, and intercooler.
One big advantage of yours over the CSF unit for Rockstar are the vents on the back. On a racetrack, the fan should be along for the ride. The extra vent holes on the back reduce the effectiveness of the fan which would be an issue on red flag situations and in NYC and LA traffic. Some shrouds have flaps over the openings. When the fan is providing suction it holds the flaps closed. When it isn't, they blow open.
Have you sealed your radiator so that air doesn't leak past it? I'm guessing most S2000s don't have a sealed duct without sharp edges. Those, I'm told, form vortices which close off some of the effective area.
On big difference of a top down vs cross flow and especially double or triple-pass cross flow is the increased pressure drop. One is pushing the water through lots of short tubes. The others are pushing through an increasingly smaller cross section and for a much longer distance. Sometimes that needs a more powerful water pump. Probably not an issue here.
One interesting think I came across is this a honeycomb radiator protector from Speedway. Don't know if it blocks air significantly (they say not) or how well it protects, But it is interesting.
