I find my pusher fans actually make a real difference. Depending on where you live,
oil coolers can be a pain if you drive your car in the winter and its cold out (less than 40 degrees). At any sort of speed, the
oil doesn't really get hot enough. I have mine blocked off with lexan right now, but that still doesn't quite do it. They make thermostats to cut off the
oil cooler loop, which you might consider. I'd probably still go with an oil cooler though.
