This is a DUAL ELECTRIC FAN that was taken out of a 96+ Ford or Mercury's.  IF YOU REALLY WANT TO COOL YOUR HIGH OUTPUT MOTOR, DO WHAT CORVETTE, FORD TRUCK AND DODGE SUPPER DUTY DOES. (USE A DUAL FAN FOR MAX AREA.).    THE MOTOR's ARE MADE BY SIEMENS, THE LEADER IN THE FIELD,   These are excellent upgrades for Fox body Mustangs Hot Rod Land Rover, and Jeeps 4x4s and many other modified cars and trucks. If you have limited area to work with, and can't use a single fan due to water pump clearance, these smaller shroud fans may work for you. These fans more than 4000 CFM on the high setting. The setup has two 12 inch blades  giving a total area of 24 inches for measuring cfm. !!WOW!!  The shroud measures 15 inches by 24 inches and is only 2 1/4 inches deep in the center and 3 1/2 at the motor center.  The shroud is equipped with a heat coil that turns the second fan on high at 225 degree.  This set up will reduce the drag on the motor and free up some extra Horsepower. These are the strongest electric fans available. The fans can be wire for several  different fan speeds depending on your need. Please email me for further questions. (This will beat after market electric fans that claim over 3000 by leaps and bounds)  Unlike those expensive cheaply made fans, the setups housing is a shroud. The shroud covers more than 90% of most of today's radiators, and can be altered to cover 100%. 
A fan without a shroud allows air to flow erratically, creating resistance.  The shroud allows the air to be concentrated on the radiator only and disperses the air evenly, cooling the entire radiators antifreeze at once.
