4188 cfm. But you really don't want all of that. The beauty of these fans is that they are variable speed. No need to blow that much air if the temps are low enough. There are controllers you can buy that will only let the fan run as hard as you need. Or for you DIY guys, there is info on how to make your own controllers in my fan thread on LS1 forums

I have a 1988 C4 that came with the "Auxiliary Cooling Fan" installed from the factory. Under the hood you will find the large standard "Puller" fan behind the radiator and when you look carefully you will find the second fan and it is "Pusher" that pushes air through the radiator.
This was done by GM to eliminate the overheating of the C4's. It is very effective to have a pusher fan helping the cooling system. If GM does it why would it be a bad idea on other Corvettes?
