Anyone using a electric water pump on the street?

If so let us know what kind.

Thanks.

 

I've heard you can do it, but it's a major PITA. I can see how one could do it though. Provided you don't want A/C and you don't need the AIR pump, you could mount the Alternator low on the passenger side, and drive it and the P/S pump off of the crank pulley. That would be some really trick looking shiznit, though.

Although, from what i've heard, those electric pumps only have a lifespan of 300 hours or so. That means you can drive your car for one hour a day for one year until your pump's motor burns up. They're meant for track-only cars that only run for an hour or two every weekend.

There are some really great mechanical pumps though. I have a
Stewart Stage 2 aluminum pump that is really slick. Their cast iron Stage 1 pumps are almost as good as the Stage 2, but cost just a little more than a stocker. I also got one of their modified thermostats. (Manditory with a Stage2) Combined with a new, stock radiator, the car never runs over 200 (With a 195 stat!) ; even cruising the Beach on Memorial day weekend.

 

i heard that CSI (i think) has pumps with a 3000 hour lifespan.. that should fit without too much modding

 

The only "street cars" that I see with electric water pumps are also tubbed and have blowers hanging out of the hood so I would think that they are not ver streetable. just my .02

 

Meziere has been testing and just put a part number on the 350 TPI electric pump. I have one on my 92 Firebird. It was a snap it works with the stock serpintine belt, Took less than an hour to install. The part number is WP 321S. It flows 55 gallons per minute. I figure it save about 9 HP.... it works great... you can call them at 800-208-1755

 

Electric ones are supposed to be for track use only.

Stewart makes excellent mechanical water pumps as stated above.

 

summit sales ones that aren't in the racing only section.. 3000 hours is alot. and there are supposed to be flow sensors out there that will tell ya if ur not flowing coolent..

 

I'm not saying that you would want an electric pump so you can sit in traffic on the 405 for three hours,(although it will do better than a mechanical) but if you have a ride that could use an extra ten HP why not get the electric. I run a 160 degree thermostat and any time I am moving or have the air on it runs right at 160-170 degrees. The biggest change I have seen; is when the car is at idle, if the fan is on, the car gets as cold as the thermostat will let it. So rather than have your engine temperature cycle between 200 and 220 with the very low flow that comes from mechanical pumps at idle, why not take advantage of what the electric can do? The Stewert mechanical stage 4 pumps are made for cup cars that operate between 6 and 9 grand. The flow they put out at idle is very low. This is not saying the Stewert pump is not good equipment, it is just the way it is designed to work. When the ceramic seals got put in the electric pumps you can expect a long life 2400 to 4000 hours. This makes them compatible with street and strip. If you drive 3 hours 6 days a week that would be over three years use before an expected repair and up to 5 or 6....... I agree that electric pumps were originally built for drag racing, but why would you ignore easy horsepower? just something to thinks about.....

 

To the post above we finaly got some dyno time.... it was 11 easy horsepower at 5800 RPM it apears to be about 5 or 6 where we started the pulls from 3500 RPM.......
