i'm running a flex-a-lite black magic extreme. pulls 3,300 cfm, but its not really enough for my heavy pig on the hot days in the desert. i never run warm when i'm crawling, but climbing grades on the highway i got to watch the temp gauge.
it came with "universal" brackets which are just sheet metal that you can bend to use as a bracket or a clamp. you can see the upper clamps on top of the radiator. i have never had a problem with it coming loose.
please excuse the messy engine bay, i know it looked like garbage.
i forget his user name might be like joefrontier or something but i belive he is using a maxima efan on his, im sure if you search for it you can find it eventually, if not maybe he will chime in, but i know a few people have done em
I run the 1990 Maxima fan with a SPAL controller. Dual fan.
The first fan will turn on slow and ramp up as needed. When the first fan cannot cool the engine the second fan comes on full. Never had it over heat on me. However, I do not rock crawl or drive up and down hills.
I don't recommend cheap controllers. I almost bought a Flex-a-lite, but went with SPAL because of the warranty and the encloser.
There is a small quick with the controller though and you have to sent it out to SPAL tech support to get the diagnostics turned off due to our trucks electrical setup (or maybe it was just mine). If you decide to go with SPAL I can give you tech supports name.
Your truck will sound quieter when you get that mechanical fan off.
i dont mean to threadjack, but beef, is it ok to have your reservoirs right above the block like that? bein exposed to all that heat and whatnot it seems like it could have a bad effect on the oil or nitrogen... whatever youre using.
not the greatest location, i know. i should have got 90* fittings from the factory and put the reservoirs on the shock hoops, but it was just one of those things that slipped my mind.
if i was racing the truck, it would be a problem, but since the primary use is rock crawling, its not a problem. in racing applications the shocks get hotter then they would just sitting over the motor like that, so no harm is done.
the biggest advantage of the efan for me was having a fan running at 100% while crawling, which produces very little air movement in the engine bay. i have never ran warm while crawling, which is a problem for some 1st gens that crawl. overheating on the freeway when climbing grades is an issue of radiator efficiency, not really fan functionality.
I vote against this mod. An electric fan doesn't pull as much air as the stock fan. There is no measurable gain in hp either. The electric motor can fail, many go bad. I use to have one on my 300zxTT. I felt it was a mod that I could have gone without. Eventually I went back to stock fan b/c of heat issues. Maybe for rock crawling it may help at idle, but anything above say 1500-2000rpms the stock fan will pull more air, and best of all, its already in there.
Good info on this topic. It was just something I was considering doing. Seems like it would be fairly beneficial to swap in an E-fan. Not too hard of an install and not too pricey. I WOULD like to know how much, if any of a gain in HP or torque it may produce. Aside from the intake and exhaust I think this would be a great way for the trail guys to get a little bit of that extra power out of the power robbed 1st gen 3.3...How would the fan be effected by that soupy mud-water though? Surely brief exposure wouldn't foul it out??
