I dont have much experience with aftermarket fans. Normally. I wouldnt replace the stock ones but that stupid hks vmount sort of requires you to
I ended up going with low profile spal fans 11"each and in suction they offer 840CFM. Driving it on the street is fine. Doing some hard pulls is also ok but at the track I could use something stronger.
The 840 cfm ones do not pull enough and my condenser ended up blowing in no time
I wonder whether the next step up to 930cfm each will make a drastic difference since they fit to the same locations as my 840cfm ones.

Any input is appreciated
Thanks

 

Your condensor blew? More info on your setup please.... and exactly what happened?

 

The oem fans have 3 different speeds for different purposes. 1st speed for the radiator when it reaches x degrees of temperature. 2nd speed for y degrees of temperature and then you have an Additional 3rd speed to cool down the a/c condenser. When you replace the fans with 1 speed fans you lose this cool feature. When the condenser is not cooled down by the fans due to the lack of your fans power the pressure in the system increases. This is where the condenser blows

 

Or you could run a solid state relay and pwm the fans to have a rising rate family speed. With max speed for the condenser.

 

Thats not my concern actually. . I want lower temps at the track
