do they give h/p or not that"s the question, any dyno numbers

 

I didn't get it for HP... I got it so i can run my fan, and the water pump without the engine on in between runs at the track. I can cool the engine back down to 0* in about 15mins.

 

Been running one for 4 years with no issues. I don't have dyno numbers before and after but I know that between the Steeda UDP's and the electric water pump the engine really does rev up much quicker. It is a worthwhile mod.

 

well the big turn off for me is whether its a reliable mod or not, i dont want the risk of the car overheating while im driving if god forbid a electric problem would arise. SOOOOO that being said, this to me is a somewhat risky mod. correct me if im wrong, but i dont have it so i dont know reliability on this mod first hand.

 

I feel the exact same way regarding reliability. But I haven't read much at all about them failing and guys like Scott (above) have had great luck for several years. I'd say it's a worthwhile mod not only for a bit of added performance but also the additional cooling as also noted above.

 

Well, I have read alot the past 4-5 years about the Meziere electric water pump and have not heard of any failures to date. I am sure they do from time to time just like a stock one. Mine is 4 years old with about 30K miles on it of daily driving. These cars will go into the "limp mode" if they overheat protecting the engine from major damage. Same thing would happen with the stock waterpump. The track record of these pumps is pretty darn good. The manufacturer claims 3000 hrs of service. Figure up how many miles of driving that is and I think you will be surprised.

 

You could just as easily break a belt..... then your car would over heat with your mechanical pump, where an Eh20 would get you as far as the battery will, possibly somewhere safer.

 

thanks for the lol.

 

Put it this way: You're out for a cruise, and after 2 hours driving you pull into a BK and turn the car off and go in for a burger. Engines off, no turning belts, no water pump.

Same would apply if yer cruising down the road and your electrics die. You can't rely on the engine to stay running.

The advantages of an electric pump are as stated above, not having to rely on the engine to turn the pump, plus it's not putting drag on the belt so you free up some power. If you're a drag racer, or you want to help your engine cool after hard use, an electric pump is a great addon.

 

my guess would be less than 4hp freed up from the change to ele pump

 

An average is 8-10 rwhp, I've seen it myself but haven't done this yet. I want to overhaul my cooling system all at one time to prevent waisting money on coolant!

 

180000 miles of is 3000 hours at a continuous 60 MPH

So expecting 100,000 miles is probably a good idea for all around driving, stopping, standing....

I would therefore swap it out at 75K. Just to be safe.

If I got one. Which I'm not. Maybe. Who knows, maybe it'd be nifty.

 

I was on the hybrid electric vehicle for my senior project at VT before I graduated in May 2008. We used an electric water pump on our 2005 Equinox converted to a Hybrid and had 0 issues. This particular one would give a little whine when running, not sure on the brand. Do you guys have the same whine with you electric pumps?

 

Pump itself is fairly quiet. Coolant circulating sounds like a fishtank though.

 

Fish tank is a great comparison Bill!

 

I guess another way to think of it is that electric water pumps in the drag racing circles is fairly common...so it's not like it's a sketchy, un-heard of thing to do. Often it's recommended as "a must"...

 

Dumb question: Do you have to create a new, separate switch to control it with?

 

No. There is a wiring kit you need. It contains a relay, fuse and wiring. You pull the power from the rear of the SJB on the passenger side under the hood. Very easy install.

 

You can also run a switch to that relay, so you could power it on at the track

 

True. But I can do the same thing by just turning my key to accessory. Because I chose a fuse tap that has power then. No other switch required!! So engine off...key to accessory and the pump is running.
