Griffin Aluminium Radiators

http://www.griffinrad.com/

100% made in the USA. Starting with high quality aluminum produced to exact specifications, our radiators are manufactured in Piedmont South Carolina, not just assembled in America. Griffin radiator cores are NOT imported from foreign countries or any other manufacture. From the bottom up all Griffin radiators are designed for high performance. 

Griffins in house mill provides tubes and fins made with thicker material for superior cooling and longer life.The dependability of the Griffin core lies in the brazing process used. Griffin cores are NOT glued, they are vacuum brazed, which provides a high magnesium content bond for superior core strength. Add this high strength core to Griffins die formed ribbed (for added rigidity) side tanks and you have a quality product.  

Manufactured with lightweight aluminum technology, Griffin radiators are the choice of top racing motorsports professionals. Our aluminum racing radiators are designed in a wide variety of racing sizes for your needs in 1", 1.25" and 1.5" tube cooling. The Griffin design incorporates open fin spacing that promotes air flow through the radiator to enhance the cooling and help eliminate clogging.

Griffin Aluminium Radiators

Stand-out innovations on all Griffin aluminium radiators include special tube and fin designs ( twin 1” tube core standard or twin 11/4” tubes on heavy duty models ) heliarc welded tanks and vacuum furnace brazed core for stronger more durable units with a finishing outer resin for a second layer of protection.

Aluminum Radiator FAQ

#1 Does an aluminum radiator cool better than a copper brass radiator?
An aluminum radiator does cool better than a copper brass radiator. For example, an aluminum radiator with 2 rows of 1" tubes is equivalent to a copper brass radiator with 5 rows of 1/2" tubes. Aluminum provides high efficiency, is lightweight, and has a longer life compared to copper brass.

#2 How many degrees will the temperature go down if I switch to Griffin radiator?
A decrease in degrees not only depends on the radiator, but also the other facets of your cooling system, such as fuel, moisture, pulley ratios, timing, etc. Griffin products are designed for a high performance level and are very competitive within the industry.

#3 Is a thicker radiator a better radiator?
Thickness requirement depends on the application. There is no reason to build a thicker radiator than required to meet your specific cooling needs.

#4 Is a cross flow better than a down flow?
The cross flow and down flow radiators work about the same. Selection is usually based on packaging the radiator into the engine compartment.

#5 Griffin race radiator sizes, is that the overall size or the core size?
The sizes listed for our race radiators are actual overall sizes.

#6 Why do Griffin use epoxy on there radiators ?
All Griffin radiators are furniced brazed together and then epoxy is applied to give extra strength to the tube to header joint. The epoxy also provides an extra level of leak protection.

#7 Should I be using any kind of additive in the water to protect my aluminum radiator?
Griffin recommends a coolant that contains an aluminum protective additive.

Cooling System Tips 

Fans move air through the radiator assisting in cooling the engine. A fan without a shroud is better than no fan. But, consider this. At idle or cruising speeds, you need the entire cooling system working at its optimum. An unshrouded fan is moving air through only the portion of the radiator equal to the surface area of the fan. For example, on a ’32 Ford, the area of a 15.50” fan is about 189 sq. in.; the core of the radiator is approximately 371 sq. in. This means that almost 49% of the unshrouded radiator is not receiving any benefits of the fan. Shrouding your radiator lets the fan pull air through the entire core.

Rule of thumb. Only choose a mechanical fan over an electric fan if it’s your farm tractor. An electric fan is preferred because when you need a fan the most (at idle or cruising speeds) an electric fan is delivering maximum air independent of engine RPM’s. Fans that move 2000-2300 CFM’s are worth the investment. Preference should be given to a “pull” vs. a “push” fan. Mounted on the engine side of the radiator, a pull fan does not interfere with air flow at highway speeds. All shrouded fans should be on the engine side of the radiator.

Without adequate air flow, a radiator is just a reservoir for hot water. Coolant transfers heat to the tubes; the tubes transfer heat to the fins; air moving through the fins dissipates the heat from the radiator. You need sufficient openings to the radiator that channel adequate air to the entire surface of the radiator. You must have a radiator design that allows the air to pass effectively through the radiator (wider and taller is better than thicker). You must consider how the heat will be evacuated from the engine compartment.

All engines have “normal” operating temperatures. Running engine temperatures well above or below recommended temperatures could cause damage. Most of today’s engines operate in the 180°-210°F range.  

Competition Oil Coolers

Normal “performance” oil coolers are fine for most street applications, but for the vibration, oil volumes and efficiency required in competition, Griffin aluminum fabricated heavy duty coolers are a must.
