is a 40 amp relay enough

to run a dual electric fan setup. the fans are about 14 in each

probably but i would use 2 cant you measure amp draw

I would use 2 as well. 1 on the Feed line to each fan. Might even wire them seperatly.
That way, if 1 fan is Failing, and starts to pull more amps, blowing your fuse, you don't lose all of your cooling ability.

Consider it Fail-over.

i could measure amp draw wiring it up sat before i go out and play. i am going to run a fail safe toggle switch.

use two- dont be a dummy

Run 2 Switches, with 2 Fuses.

IF you blow the Fuse, and IF you dont have one, your stuck. You may lose a motor.
Its Really not that much more work...Just run 2 fuses/lines/switches. Its no more difficult that wiring in 1 switch.

40 amps should be more then enough to run two fans.

What size wire is coming off the fans? To get a true 40 amps you would have to use 8 gauge.

why would i run two switches? thats an over abundance of wiring. its a simple circuit. why over complicate things with what ifs? i have this magical thing called a temp gauge. if if starts to overheat and my relay fails and my toggle switch fails and i'm sitting in traffic . guess what i'll shut the motor off problem solved.

Not likely that the fans draw more than 30a continuous combined. 40a is the continuous rating btw. The fan should have a draw rating on them, or be available from the mfg.

The dual fans from an SVT contour are on an 80 amp...

Not saying... just saying..

However, they are multi speed, so that may be why.

I have personally had to replace the 80 amp, in the under hood box, more than once, because of a single fan failing and over drawing...
