The Competition Cooling Kit with Offset Fan is designed for race applications where temperature management is even more critical. The kit includes, in addition to the benefits of an all alloy radiator, an alloy fan shroud, alloy overflow tank, aluminum cap and a 14 inch Spal electric fan. The offset fan feature was designed for twin cam six engines that have been fitted with a Dinan Supercharger. This design compensates for the supercharger’s pulley.
The electric fan and the alloy shroud work in concert to provide maximum cooling efficiency. Simply hanging a fan on a core won’t do. The airflow must be directed through the entire core area, not just directly in front of the fan. The latter approach limits the effectiveness of the core. Essentially, it reduces the core size to the diameter of the fan. Not a good practice. The alloy shroud in combination with the electric fan creates a low pressure area in order to direct airflow over the entire core surface. Additionally, this setup allows for the removal of the engine driven fan and clutch as well as the auxiliary fan in front of the radiator.
By eliminating the stock plastic overflow tank, the Competition Cooling Kit with Offset Fan affords an extra level of protection. The stock overflow tank has the potential to become brittle with time due to constant temperature cycles. The alloy overflow tank with not become brittle or crack.
Lifetime Warranty!

WIRING OPTIONS
This is the recommended approach. With this option, the SPAL electric fan is wired into the existing car harness and operates on the auxiliary fan circuit. However, to remove the factory auxiliary fan, one must dismantle the front end of the car. It’s a lot of extra work, but the results are worth it. This package includes the necessary wiring components for single (high) speed operation.
• Auxiliary Fan Delete II
Same as above, but this version includes additional components for two (low-high) speed operation.
• Single Speed Fan Kit
This option includes one wiring kit. The factory auxiliary fan is retained. The SPAL fan operates at a single speed on its own circuit.
• Two Speed Fan Kit
This option includes two wiring kits and a resistor. The factory auxiliary fan is retained. The SPAL fan operates at two speeds on its own circuit.
