Dual core, or dual pass????

Whats the difference,which is better, and can they be combined??? i live in las vegas where summers reach 110... just trying to find a good cooling setup

A multi-core, or dual core radiator has has that many rows of cooling fins. These types of radiators often hold a greater capacity as they tend to be thicker. The drawback is:

• Thickness (fitment)

• Pressure drop (adding more cores increases pressure drop)

A multi-pass, or dual pass radiator passes coolant through the radiator twice. You will often see the inlet and outlet on the same side. The biggest benefit to this type is that you are increasing the surface area thus also increasing the time the coolant takes to travel through the radiator maximizing heat dissipation. These are also available in dual core configurations.

The biggest focus should be fans and ducting. The OE fans have proven reliable and powerful, but take up more space when using multi-core radiators and larger turbo setups. Spal is among one of the best aftermarket solutions for cooling in a compact unit. Ducting to the radiator ensures that air is going through instead of around the radiator. This is specifically important when running multiple heat exchangers (intercooler, condensor, radiator, etc.) in a row.

whats the draw backs of the muilti pass radiator... i only have a 4 inch intercooler in front of the radiator and it only blocks the bottom half of the radiator

They can slow coolant flow to some degree. That is also where a dual core can help as well. The other possible drawback is that the inlet and outlet would likely be on the same side.

Thanks alot... that helps, with my decision...
