My buddy is thinking of installing a electric water pump on his engine. it is a 350 chevy. The pump he is looking at pumps 35 gal per min. does anyone know how much a stok pump will pump?

Depends on the rpm.

hi 4 jaw iwould like to what flow rate is at idle say average cruise speed 4500 RPM the electric water pump i am looking at claimes 35 gallons per minute so with out knowing what stock pump flo rate is its hard to do comparisen i suppose the biggest gain with electric pumpis its always at max flow all the time thank you <img src="confused.gif" border="0">

I installed a meirez remote elec.water pump on my 33 Willys coupe,not enough room for mechanical water pump plus fan.It works great,I mounted the water pump on the front cross member,then plumbed it with 2 #14 stainless steel lines to the front of the motor,my pump is 55 gal per minute,What I was told that a stock pump only pumps 15-20 gal.per minute,i don't know how true those #s are.This pump I installed is for street use,Keep in mine that when they call out 35 or 55 gal. per minute,that is in a perfect world,I could not guess the rate of flow on my 55 gal. pump.with elbows,line size,thermostat opening size,etc.I had to go to elec. pump.I would have like to stay with the stock setup if I had room.Hope that this helps.

Depending on the use definitely go for the electric for any street use. You don't end up losing the horsepower and it has at least a third better flow rate than mechanical.

Im not shure how much a stock pump flows but I do know he will goe a knowtisable horsepower increase
however he will have to sacrifice hes power stearing thay have kits to drive altanators but Ive never seen one for power stearing. Ive been thinking of getting an electric fuel pump for a wile now just for the fact that with out a belt driven pump a small block will wind up with quickness
