The structural integrity of aluminum is much stronger than copper/brass. This allows us to make larger tubes which can push a larger volume of coolant. This also allows us to have more fins in contact with the tubes (16 fin per inch!). All of these factors contribute to greater heat dissipation and a more efficient radiator.

Because aluminum is much stronger than copper aluminum core manufactures are able to make the tubes up to 1.50" wide, opposed to .50" wide for a copper tube. The benefit of this extra tube width comes from the additional contact that is created between the fins and the tubes, as there are less spaces or voids between the tubes (due to a fewer amount of tubes).

It's true that Aluminum dissipates heat significantly better that Brass and only slightly less than copper, but the major benefits of aluminum radiators are in the design differences. If you take a look at a cut away section of copper brass radiator that is 2.25" thick, then multiply the number of tubes in a row by the width of the tubes you will find that there is a total of 1.50" of "contact" between the fins and the tubes on every row. Now, do the same evaluation on a 2.25" aluminum radiator core and you will find that there is 2.0" of "contact". That is 33% more "contact" than the copper brass. This is critical as the fins accomplish a large percentage of the heat dissipation. The less contact between the fin and tubes, the less effective the radiator will be.

A important benefit of the wider, aluminum, tubes is that a larger volume of coolant is now placed inside the core, where the heat dissipation is occurring. Between the additional contact between the fins and tubes, the additional fluid in the core, and the additional contact between the fluid and the tubes you can expect to see at least a 25% increase in the heat transfer capabilities of an aluminum radiator over a copper/ brass of the same thickness

Yes you can. Keep in mind that all of our products are build to order, so your order will be somewhere in our production and will most like be "completed" to some level. Because of this we do charge a "Cancelation fee", which is 20% of the value of the order.

No, not necessarily. The important factor is the amount of heat dissipation surface the core has. The coolant flow direction is not important

Many aluminum radiator manufactures make "cross flow conversions" for many original down flow radiators. Although these radiators will cool better than the original, they do not look, mount, or fit like the original These cross flow conversion can require anything from new hoses to major sheet metal modifications. Cross flow conversions are the easiest and cheapest to design and manufacture. An installer must consider the cost of additional modifications that are needed when considering a cross flow conversion.

Although Wizard Cooling is fully capable of producing cross flow radiator our primary focus is to design a build a radiator that will be configured like your original, fit the original radiator mounts, and cool what ever horsepower you have.

No, running a lower temperature thermostat will not bring down engine temperatures, it only controls OPENING TEMPERATURES.

The only "benefit" is that you have now increased the amount of time it will take for your vehicle to reach operating temperature. A thermostat is supposed to modulate, just like the thermostat in your house turns the furnace on and off. When the coolant reaches the thermostat setting it opens and lets coolant go through the radiator. The radiator, if capable, will drop the temperature down to a point the thermostat modulates.
