i want to make this timer not bcoz i wan to cool my engine down, my point is i wan to cool own my engine bay, let it cool faster in few seconds, coz i got a DIY-ed VS in my engine bay, cannot exceed 85c or else the caps blow.. -__-.... Now everytime i come back oso open up my hood let it cool sked my caps rosak =PP
wad u mean idling speed is high enuff and should not be a jerk?

i see, then i misunderstood your purpose. sorry about that.

i mean build a real turbo timer as in let the engine idle for a while before switching itself off ;)

time t=1.1 X R1 X C1
=1.1 X 680K X 33uF
=1.1 X 680000 X 0.000033
=24.684 second.

just changed the R1 and C1 to get what time u need.

I mean the timer will run all the time even the egine is off...
Rite...??
Then the DIY timer wont last tat long,rite...??

 

[www]

Rite... run all the time. but can last long because just stanby, not run the timer. like alarm system. that circuit for sample only. it can modified to cut off when you need.
