10" or 12" Fans..Quick Answer

[eclpsegsx12]

Im buying new slim line fans and i cant decide whether to get the 10s or 12s? Will the 10"s flow good enough for a fully built motor and big turbo ect...???Thanks

I have 11inch on the AC fan I believe the Spal's people were using for the rad, fan was a 12 or 14.

the dual spal 10" is definetly enough (the one with the shroud)...

If you can fit a 12 why not do it? If its a space issue then just put the biggest in there that will fit. I have a 12 and 10 on my FWD car.

Im running a 550cfm 10 inch fan as my primary one on my car......with the stock A/C fan on the other side in case I see it getting hot on a really hot day so I tun on the A/C to get the temperature down to normal......once I get moving I dont need the A/C fan on anymore......so if one 10 inch keeps my car cool most of the time......two will definantly cool it for you

Not degrading your point... but a lot of fan designs expel a larger percentage of the air off the tip of the blades as opposed to the entire length. I have seen peopel sticking as large of fans as they can and have probelms because most of that ait flows over/around everything as opposed to going through it....

I got a 12" slim (800cfm) on the passenger side of the radiator. Keeps temps perfectly within range even on hard runs. I have no fan on my driver side though cuz i took out my a/c, but there is plenty of room there even w/ my external wg and manifold to mount an additional fan for even more cooling.

Peace
