Hey, well as per my thread earlier:

I purchased an 11 x 11 x 2.5" core. Now, would it be beneficial to run 2 fans, 1 in front pushing and 1 behind pulling to help with cooling? This is for a 400+whp setup and 11 x 11 might be too small? but thats the only sizei can fit max

One fan. Make a shroud if you can.

 

1 fan pulling air is the best you can do. That is a small core for a turbo gas car.
