Can anyone tell me the CFM on 93-95 stock twin e fans?

I read they are 11" with 2780 CFM ( 1390 x 2 )


But my buddy says one is low speed and one is high speed...you can do a mod to get more cfm/rpm out of them?

Please help...getting a Godspeed or Megan 2 row aluminum radiator- they come with twin 12" E-fans pushing 2500 CFM -1250 x 2


Any info or suggestions for fans?

Don't know the specific numbers off hand, but the FD fan assembly is pretty robust and moves alot of air. Unless there is some unavoidable packaging issue, you probably want to stay with them. IMO that means only getting an aftermarket radiator that is specifically designed for the FD, it's hose location and especially it's fan assembly. If those Godspeed or Megan ones aren't, get ones that are.

Thanks for the info...unfortunately, I don't have the stock fans, I would use them if I did

They both run at the same speed. High, Medium or Low. There is a difference in blade count, but that was done by the factory to eliminate some issues with resonance.

I wouldn't trust the CFM ratings on off-brand fans. They commonly over-rate their products.

If you want to use aftermarket fans, you need to get SPAL fans (reliable, and with honest specs) and make sure they're properly shrouded like the stock fans so that you're pulling air through 100% of the radiator core.
