Whats your CFM?

[WatchMyDrift]

Just was wondering what type of electric fan other M30 swap guys are running. I have a small fan that I used with the M20, but I dont think the cfm's are enough.

My question is, what CFM's are you running and what size fan?
Is there really much difference in cooling between a 2000 cfm, 2500 cfm, and 3000 cfm?

Also is it even possible to use a puller fan over a pusher (what distances are you getting between your motor and radiator. Is it enough to stuff a slimline fan in there?)

Thanks

idk you'd have to look it up but it's the slim spal one. I think it's 1,300cfm.
unless the engine is put back a ton you can't do puller..

Get the biggest Spal you can (16" I think) and mount it as a pusher
