Re: [DML] Fanzilla Clones

["Shain Brannan" <dsmguy@xxxxxxx>]

Ryan,

Installing new fans into your car is an excellant idea, and i have 
heard good things about John's new fans.  Although this is a partial 
solution, you are looking at the problem in the wrong viewpoint.  
The problem is not the cooling system,  but the instant draw of 
current two fan motors places on the electrical system when the fans 
engauge.  Your new fans may only run on 11 amps, and most likely 
pulls double that on startup.  This is why Fanzilla and my module 
attempt to stager the cooling fans.  If the only problem we had were 
fan motors sizes, and the amperage it pulls there would have been 
new fan motors over a decade earlier.  As for fan motors a good 
friend of mine has 600k miles on his fans, and there still going 
strong (bosch builds nice motors).  I'm not trying to say your 
solution is bad,  it is just part of the solution.
