Re: [alfa] Mechanical vs electric fans - was single row timing chains

[Ed Lutz <edlutz@xxxxxxxxxxxxx>]

I don't know what the actual HP increase is but you can feel it. After 
removing the mechanical fan on a car I once had, a car with HP to spare, 
great gobs of HP in fact, I could feel a quicker response to the throttle 
coming off idle and that the motor reved easier than before. Its a mod that 
sits right at the top of the list of things to do to my Spider when I have 
time and money, right after I figure out where the nasty engine knock is 
coming from...
