how much voltage is the car battery?

[raymond]

Hi all,
Want to know how much voltage is the battery in the engine bay given if directly bolt on something on it.. if I no mistake, should be 12 volt right ?


anybody thinking of putting a FAN with 7200rpm in the AIR FILTER there?

kakakaka...

much more smooth?

:lol:

 

[evo5755]

could go up to 13.9 or 14.5 volt

if engine off, around 12-12.5 i think. on it will b around 14-14.5, if u on the aircond, head lights n such......mayb around 13.5?not sure, but it will drops

there're fans that spin at 7200rpm or even more...
but then it still can't build up enough air pressure for your engine intake... at low rpm, maybe can work a bit but definitely cannot at high rpm... the fan will become a restriction at high rpm...
somemore the fan will not be able to withstand the heat inside engine bay...
there're a few discussions about fan or electric supercharger here... just look around ;)
