I was thinking about this as a winter modification. It would certainly be much cheaper than buying an electric pump.

I dont drive the car on the streets much at all, its trailered to the track.

Would it be worthwhile? moroso electric drive

 

What I can't understand is the need for people to replace belt-driven fans with electric, or in your case, turning the pump into an electric drive. Any load that you put on the alternator, will still bog the engine down. Electric motors waste tons of energy. Just like a light bulb. Make any sense?

 

Ok man... I just know what I've seen ran on cars at the drag strip since i'm there every weekend. 100+ cars all runnin electric fans and water pumps with guys that have done it for more years than i've been alive can't all be wrong.

Anyone else have EXPERIENCE with something like this?

 

The only experience I can offer is when I put a SBC engine into my Fiero I used an electric water pump. The pump only used 4 amps of power. I loved it, the temperature would stay around 180 and when I was on the highway the temperature would go up into the 200's and when I was back in town the temperature would go back down. I was thinking of putting an electric water pump into my Trans Am when I put another engine into it. The thing I would do if you put an electric pump into your car is put a light in the dash so you can tell right away if the pump looses power due to a blown fuse or whatever.

That'll work for a trailored car and free up a couple hp at high engine speeds. Just understand that you'll loose a lot of flow rate vs a designed electric version. The mechanical pumps are designed to have a broad range of speed and with speed comes flow rate. The elctric motor will only hold a specific speed (if it's a cheap on/off switch) and that'll limit the cooling system to track only. Those kits are also not ment to be run for extended time periods.
Back to reasons why you should use it. One less belt to fail (just 2 wires) and you can let it run after you've shut down the engine to cool down the engine faster imbetween rounds. Just remember that if you're using a small battery that you're limited by amp hours. So keep it on for like 5 after a run and turn it off .

 

Thanks for the replies, that was one of my main concerns, being that there is only one flow rate. But I also like the fact that i can run the water pump with the engine off.

If i do install an electric water pump, i'll be taking a generator and a batter charger to the track with me.

Does anyone know the max (or average maybe??) flow rate on a standard chevy pump?

Also, does anyone know how many rpms the moroso drive spins. Or what it is equivalent to engine rpms?

 

When/If you find out please post it.
