I went to a few places today to find a relay and either they needed a part number or tried selling me something else. I did however find this at a local shop http://www.summitracing.com/parts/DAI-0 ... /?rtype=10
it says for headlights but I figured it would work. I could connect each fan directly to it's own prong. Think it'll work?
as long its 30 amp it will be fine .my drawing dont show each fan to its own prong........follow the drawing i did for you guaranteed to work. unless you doing something different.
I installed a Mark 8 fan im my ride and it draws some serious amps on start up, so i used a continous duty solenoid instead of a relay, its rated at 90 or 100 amps and only cost me about 25 bucks from advanced auto parts

I used a 40 amp fuse for two 13.5" pullers. Don't remember what they drew but they could move 5200cfm. At the time I did not know about useing the newer better stronger altenators so I had an altenator shop rebuild mine to about 85 amps and add a low rpm pulley so that by say 1500 engine rpms the altenator putting out near capacity. With the electric fans electric fuel pump stereo & lights I needed the juice at lower engine rpm as I had an overdrive and motor didn't turn more than 5,000 rpms anyway.

yea them " si " style alternators are like that they need to spin to put out .shops love to run pulleys like that to make them spin more makes the unit fail premature...that is why i run the " cs " style alternators they put out 105 amps at idle ! (that is stock output also lol) .yes the cs alternators drop off alittle on high rpms but your not going to be doing 5k rpms for long periods of time .i been modding them now for a long time and there smaller in size than a si alternator in todays times our cars are power hungry monsters and we need the power up front for street cars/mild racers.
I'm running an alternator from a 95 roadmaster it rated at 140 amps, uses the same si to cs adapter wire and all i had to do was tap the top hole to accept a bolt
