FAQ

Q- How many rows do I need?

A- In aluminum, 2 rows of 1" or 1.25" tubes should be plenty for most street and mixed-use drag vehicles. Our 2 row models will outperform a copper/brass 4 row by about 10-15%! Also, you don't want a 3 or 4 row alumnum radiator. You want bigger tubes with an aluminum core because of the way it transfers the heat.


Q- Which antifreeze should I use?

A- A 50/50 mix using distilled water and ‘green’ antifreeze is recommended. Aluminum does not seem to hold up well with 'orange' antifreeze products.


Q- Will I lower my temperature if I increase the flow with a High flow water pump?

A- Not necessarily.   Flow is not as important as pressure. You want pressure in your system to reduce cavitation(steam pockets that get trapped on the walls of the system.     One commonly overlooked aspect of increasing pressure is the Water pump pulley to Crank pulley ratio.   You always want your crank pulley to be bigger than your water pump pulley.   (overdrive your water pump)


Q- Can todays fuel affect the temperature of my engine?

A-  Absolutely. Today's fuels burn a lot hotter than the past high octane fuels containing lead.

 

Q- Should I go with Pusher or Puller fans?

A- Most vehicles are set up with puller Fans from the factory. Pulling fans pull air through the radiator at least 20% more efficient than pushers. One reason is that you can only create a suction affect by pulling air. A pusher fan would perform worse if a shroud was mounted on the pushing side. That would block forced air from hitting the radiator when at cruising speeds. Pusher fans also restrict air flow into the radiator at cruising speeds
