COOLING SYSTEM PROBLEM FIXED

The problem with most electric fans is that if they get a little flow resistance in front of them, the actual flow drops into the toilet. Radiators create considerable pressure drop as air tries to flow through them, especially 2 and 3 row ones. So most fans are going to crap out. I have tried to dig down into much of the fan literature to get the flow versus pressure drop curves with little success.

But, if you have thin balded fans, then they have this characteristic of the flow going to heck with any real pressure drop in front of them. The air just flows from the back of the blade around to the low pressure area in the front of the blade and just keeps going around and around.

There are some very successful designs of electric cooling. I raced a Mitusbishis Starion for along time for a long time and it cooled fine with the factory fan setup, even with the HP upped to 275 Hp from 2.6L.

Can you tell us the brand of the fans? Have a pix?


Thanks for you input, its a champion radiator setup I purchased from ledfoot racing # CC2374b, with (2) ten inch fans, I think they are Spal fans acccording to Ledfoot racing, I think they are only 749 cfm each, I was told it would take 2100 to 2500 cfm to cool my engine after the fact it didn't work, so they were going to sell me a 16" electric fan and a alum shroud for another $250.00 dollars,my complaint which doesn't really matter at this point was, they shouldn't have sold this setup to me if they knew it wasn't going to work, then try to sell me something else that may or may not work, I gave them all the specs before I purchased, A lesson learned that you can't trust every body that trying to sell something, some time its all about the sale ($$$$$)
