i know i know this topic has been covered over and over but i am confused.

i recently put a e fan on my 12a 85 rx7, the fan came from a 97 pontiac grand prix...what i want to know is...

1.) what is the amp draw of this fan? how could i find out?

2.) is the amp draw consuming more HP then the stock clutch fan did?

3.) also i know there is a formula i just cant find it, to figure out HP consumption per amp or somethign like that


thanks

efans r alot cheaper from a salvage jard. what's the car being used for that the effects of amp draw on hp is even a concern? probably no more than all accessories on at once. and if u use a thermoswitch it wont be on all the time no way.

Easy, find out what size fuse that fan had originally. Your amp draw will be less than that.

They are usually around 20. No, your E-Fan wont take up more HP than the clutch fan. Especially if you have a decent alternator.

another ? for yall!
im using this exact wiring in my car but with a 30 amp relay

now say i wanted to use some sort of timer to leave the fan running for about a minute or two after i shut the car off, first what kind of timers are out there that would work for this? were would i get one? and were in the circuit would it go? i was juts looking on summit, a turbo timer would work but thats wayyy to much money to spend on a cooling fan lol, ive seen accesoriry timers on cop cars for the radios, were do you get those? anyone know?

thanks again
