mas28O Posted July 28, 2003 Share Posted July 28, 2003 2000 cfm ?? Is that low? I thought they put out more than that. Mike Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted July 29, 2003 Share Posted July 29, 2003 2000 cfm ?? Is that low? I thought they put out more than that. Mike Note they say estimated. Don't get too hung up on CFM ratings for fans and such because most are rated in free air. Once you put some restriction in the flow like a radiator, you really start to test the efficiency of the blade design, shroud and motor. Remember the infamous 600 cfm electric supechargers? The real number that stands out is the current pull. 40 amps at 14 volts is 560 watts of power. The black magic fan only pulls 13.9 amps. At 14 volts that is 195 watts. Which fan works harder to move air? Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted August 8, 2003 Share Posted August 8, 2003 40 Amps pull even though intermittent could be something to consider depending on your use. 40 amps definately require a good strong battery especially in light of the other draws on the system.

The battery is just to start the motor. The alternator is what powers everything when running, but at idle that fan might exceed the alternator on an old Z.

Guest cbrunberg Posted August 17, 2003 Share Posted August 17, 2003 How can you test real amp draw -vs- the advertised amp draw of the fan. Where would you place a tester and what kind of tester do you need. ( I fried a VOM last time i tried to test my alt). Carl Quote Link to comment Share on other sites More sharing options...
pparaska Posted August 18, 2003 Share Posted August 18, 2003 I use a panel meter ususally (50 amp) to do stuff like that. Quote Link to comment Share on other sites More sharing options...
TomoHawk Posted March 15, 2004 Share Posted March 15, 2004 Can I assume that this fan will go on even when the engine is OFF? New cars have that feature, so I wouldn't want to come back to a car with a dead battery because of the fan. Quote Link to comment Share on other sites More sharing options...

( I fried a VOM last time i tried to test my alt). They have inductive amp sensors. Maybe there's an accessory for a VOM that gives you the amps in the form of millivolts on the display.

j260z Posted March 16, 2004 Share Posted March 16, 2004 that's the exact fan i just picked up at the junkyard yesterday. i got one for $14 CAD. Quote Link to comment Share on other sites More sharing options...
Guest battg8r Posted March 18, 2004 Share Posted March 18, 2004 Are there any clearance issues/problems when this is installed with an L28? Would the GM alternator upgrade solve the high amp draw problem? Thanks, Quote Link to comment Share on other sites More sharing options...
seekerfkf Posted April 10, 2004 Share Posted April 10, 2004 I have an idea to use a couple of relays and sensors to use both low and high speeds on the fan ( I have the fan in my 73 and I like it but it is noisy on high speed). Anyone tried it? Any perceived drawbacks? Quote Link to comment Share on other sites More sharing options...
