Is the electric 3.8 taurus fan better then the stock fan? And at what CFM does the stock fan flow at? My dad says that the stock fan will be better since it's mechanical it will do a better job at keeping the engine cooler he says. I believe that he's completely wrong and that the electric fan will outperform the mechanical one by alot.

The electric is a great mod, i havent done it yet but it's on the list...Frees up some HP, cleans up the engine bay, and you can control when it comes on.

the electric fan will pull 2200 or 4000 cfm depending on which wire u hook it up to.. and u will gain hp your engine will stay plenty cool enough with that fan over the stock clutch fan i am going to use mine on my 347 stroker with a standard flow waterpump.. i do have an aluminum raidaitor but u will be fine with a stock motor.

Well the big advantage of the electric is it is only on when you need it. Like when you are driving on the freeway, you don't need a fan, so it is off.

will the stock alternator be able to handle it? Or should I upgrade to a 150 amp before hand? Or what do I do If I want to upgrade to the 200 amp alternator?

Well, it will be a strain for sure. The stock alt puts out like 75 amps on a good day. A good fan will draw about 15 amps, leaving 60 amps for everything else. At idle, it might only leave 40 amps for everything else...

imo you should upgrade the stock alternator to a 3g anyway but as far as amps 100 would probly be fine.....having the bigger ones wont hurt tho

Does it at least give you alot more over stock or no? And did you just connect it to one spot or did anything else to it?

yeah it doesnt pull down that easy.....usually it sits at about 13.8 volts and i was expecting more like 14.4 but oh well....as far as hooking it up you just run that one wire to the positive on the battery and thats it.....the two plugs that are on the original alternator you just leave hanging.....i know it sounds weird but thats all you do to hook it up

i cant remember for sure what they were stock......maybe 13.6 but it didnt take much to pull it down....with the headlights and heater it was gettin down in the mid twelves or so......my is reman. though....my stock tacoma alt sits at 14.3 usually and its only 80 amp is why i expected the volts to read higher

yeah thats because its a 2g externally regulated alt and the upgrade is a 3g internally regulated......one of the best parts about it is the much better voltage at idle
