does anybody have a pusher fan as well as a puller fan...meaning one in the front of the radaitor and one on the back side..?.or is that a waste of money...?.-lky-
The stock turbo car has a pusher fan, in front of the air conditioner core. Not sure if the N/A does, but I think so. Unfortunately it's not sealed to the radiator core, and hence it's not very effcient at helping out the radiator cooling .
Extra pusher fan:
That would work good, as the core of the radiator is only approximately 1/3 open, so we get high static pressures, on the fans (higher static pressure = less flow from fan).
The big hurdle is where to get the extra power, to power these fans. An extra 12" fan, at 15 amps, is a lot of load on the charging system, that wasn't designed for it, assuming you already have the dual flex-a-lite setup (30 Amps alone).
I have a 150 Amp alternator (stock is 70A for N/a, 80A for Turbo), and I don't think I could even run 3 of these fans, with my stereo on, at idle, without discharging the battery.
Better idea is to increase the efficiency of the flex-a-lites, by making a stand-off shroud. It's almost like getting something for nothing.
