I've been running this fan for over 4 years now with both FMIC and SMIC. It's the best Efan setup for very little cost. Picked it up at a junkyard for $15 added a thermostatic controller from Autozone and 2 relays and I only run on low wich is more than enough. Actually i had to use high when I had the Apollo Fmic but only on high boost. Google search will show that this fan is very popular in many high horsepower drag setups.
