thanks i was thinking about the e fans and ive heard mixed opinions on if they actually work
E-fan is a no brainer, best upgrade you can do to a mechanical fan engine
Better power and better MPG, outside of cutting parts off your vehicle to make it lighter nothing else does both.
Here's the thing, when you you need the cooling fan the engine is warmed up.
And radiator is warmed up, until then it is just a unneeded power drain
Radiator is cooled by air flow when driving above 30MPH, when in stop and go traffic or sitting and idling the fan is needed to keep air flowing thru the radiator, only reason it is there.
Now you won't get good MPG and don't need good power in stop and go traffic or while idling.
And this is when the E-cooling fan is on and drawing power from alternator, which will use MPG and power, e-fan power has to come from somewhere
OK, and when do you want to get good MPG and want good power?
It is when you are driving, and you have air flow thru the rad from vehicle speed, so E-fan is OFF, no power draw from alternator.
PERFECT fit
Will you free up 10, 20, 30HP?
No f'ing way, lol, 3 maybe, not 5 for sure, so is it worth it, actually I think it is, but just my opinion
