hey everybody..does anybody know how much cfm the radiator fan is blowing out and how many amps its using on the 85 vette???as we all know the cooling system on vettes are not that great...im looking to up-grade my fan by 1500 more cfm then the stock fan...before i shell out alot of cash on aftermarket high performance fans,its important for me to know how many cfm my stock fan is blowing out...because as we all know the more cfm the better the cooling...

[/QUOTE] well today i got the gm archives department on the phone..they told me that the fan cfm wasnt recorded in there files..they did tell me that the fan is runing at 2100 rpm and is using 12 amps...it seems that the cfm on the corvette fans are top secret information...also i called up spal factory fans today and i told them about the perma cool fans are blowing 2950 cfm and using 9amps,they argued that it was impossible for a fan to use 9-amps and blow out that many cfm...shopping for a fan is a lot harder then i thought..the guy at spal said if the fan is using alot of amps the cfm is high..im like hey my stock fan uses alot of amps,how am i supose to know which after market high performance fan is an upgrade from my stock fan...im about ready to give up on shopping for a aftermarket high performance fan,and go to the local u-pick junk yard,and get a 20 dollar 16-inch fan off of a caddy and put it in front of my radiator and use it as a pusher...that should work pretty good combined with the stock puller fan...any sugestions????Joel Adams
