Dual Radiators: series or parallel?

[Procharmo]

those two radiators combined are smaller than the radiator in my 97 Cavalier daily driver- and i don't think i'd even try cooling a stock small block with it..

True. I was hoping that two smaller radiators would cool more than one larger of twice the size... I may be able to go larger but at greater cost. I also have location and air flow efficiency to take into account. I have installed a separate transmission cooler and additional oil cooler to further reduce the work the radiators will perform.

Here are some solutions others have come up with......



As you can see the Olds is quite a wide car and he has plenty of room. But remember it is a single gear drive. (It's a Big block).

This Camaro has had the chassis chanelled to allow deeper radiator in an optimum air flow location.






My car is a 2nd Gen. With more length and less height, however I do not wish to cut the chassis and would like to preserve its cornering abilities hence smaller radiators...

I could go for a third above the blowers. Below is an example of the room I will have to play with.......

This car has a single 22 x 13 radiator on a 660 BBF but it's not a street car hence the in efficient air flow location.

This car has no radiator. I guess he is using his A/W reservoir as an engine cooler as I know he is not on meth...


This is where its got to go. I can fit 12 x12's, 10 x 22's maybe 12 x 22's at a stretch but they will be close to the front wheels and will collect road debris.
