I'm looking for a timing chain set for a 94 that doesn't have the water pump drive built in. I want to keep the stock timing cover and non vented opti.

 

the water pump drive isnt built into the timing its its own separate gear thats run off the cam gear

 

Curious why you want to do away with the gear driven pump?

 

electric???

 

That's what I figured, just wanted him to say it, and why!

 

lol... you can run electric without removing that gear

 

Going electric. but i have it all apart, see my sig, and theres no point in having the drive gear in there to drive nothing lol

 

Going electric to "free up" some h.p. I presume? You do realize that an electric pump puts more load on the alternator, which in turn robs h.p.? Energy doesn't come free.

 

You can mathematically determine the horsepower cost at any given load. So lets do it exclusively for a 5 amp water pump


Amps x Volts = Watts
Watts / 745.7 (one HP) = Electrical HP Produced by the Alternator
HP x 15% Efficiency Loss = HP Loss
HP + HP Loss = Total HP Used

So this would be our EWP:

5A x 12V = 60 Watts
60 Watts / 745.7 = .080 HP
.080 HP x 15% = 0.12 HP
.080 + 0.12 = .2 HP Total

Anyone know much horsepower to run the driven pump? less than .2 HP??

 

So for an apples to apples comparison, how does the h.p. the motor in that electric water pump consumes compare to what it takes to spin a dry mechanical pump? Your pump's motor may be rated at a 5 amp draw, using .2 h.p., but what that formula doesn't tell you is what the added h.p. load of pumping the water would be. The pump motor can run on .2 h.p. dry, but not while pumping water.
