3-4 hp with stock airbox and drop in filter and 3-4 for an open intake. The loss of torque with an open intake is what I don't like. Yes, the dyno isn't real world when compared to real driving, but the big fan up front does help a lot. My last two cars have been turbo'd and it seems to me that dumping even hotter air from the engine into the intercooler decreases the efficiency of the intercooler. I am not that versed in na engines, but it seems to me that colder air would benefit them, too.
