Hello all!

Just registered on this site after doing alot of research on e-fans here. I ordered the ls1 fans on ebay and a controller from dc controllers. My question is that I've noticed that some of the ls1/lt1 fans appear different. Some have what look like vents above or below the fans and some are solid, no vents on shroud. Is there a difference in how these fans perform?

Thanks

 

I am not sure if there is a performance difference. The ones with the holes above and below are LT1 and the solid shrouds are LS1. I belive the motors are the same and they pull the same amount of CFM's.

Buyer Beware. If you buy LS1 style fans make sure they came out of a car with a V8 because they used the same style fan shroud for the V6 engines but with much less powerful fan motors.
