Has anyone switched out their stock water pump for the electric water pump, and if so what kind of HP did you see on the dyno.

I'm looking to hit 300 RWHP with a 4.6 2V N/A and I want to know if the electric water pump is what they say in HP gains.

Electric pumps are too expensive, get something like a stewart water pump and save the money for something else.

I've been running the Meziere Electric Water Pump for around 50,000 miles. I put it on at the same time that I installed the supercharger so there is no way to know for sure but I suspect I got 12-15 hp transferred to the wheels. An n/a car would get maybe 7-8.

I've had a lot of mechanical water pumps go out. It always seems to be at the most inconvenient time like on Sunday driving across country.

think of the hassles if you were in the same situation with an electric, no pulling a replacement off the napa shelf

If you already have Steeda UDP's and are N/A, your gain would only be about 2-3 rwhp.

Actually it is pretty close to pulling one off the NAPA shelf. It has the exact dimensions of a stock water pump with an idler pulley. The reason I bought it was that my supercharger install was stalled. It wouldn't fit with the under drive pulleys the previous owner put on. I did not have a stock water pump pulley. Instead of buying it and moving backwards in my build I chose to buy the electric water pump. If the dang thing crashes on the road I get a stock pump and pulley.

I've had many mechanical water pumps go out in the past, along with alternators and starters. So stuff does break down, **** happens.

The Mezeire carries a 2 year warranty, won't find that with any mechanical water pump.

What happens when your radiator elecric fan dies? You switching back to a mechanical fan, I don't think so!

Hey, I had that happen while traveling in the summer through Alabama. As long as you are at interstate speeds everything is fine. Whatever you do don't go into town and stop at a light. It will overheat fast.

2 year warranty my ass, i bought one from mezier and it leaked from day one, sent it back to them, and after about a month or a month and a half, i funally got it back, and it started leaking again, sent it back for a second time, got it back finally, and it failed completly after about 30 miles, so i just switched back to a mechanical pump after mezier told my builder all they could do was repair my old one and not replace it.

Did they refund your money, or did you just give up?

Reputable tuners have seen 0-4 rwhp in most cases. Not worth the alternator drag.:(

I only argue the mechanical pump due to price difference, seriously for something close to 150 + shipping you have a stewart pump. You almost have enough money to do a stewart pump and an aluminum driveshaft for the cost of having a meziere pump. Id say that would be a better use of money, if money is an issue.

I have one and love it. Never have to worry about over heating if a belt breaks until the battery is dead.

another good point on the electric pump is you can wire it into a seperate switch along with the fan and keep both running in the staging lanes with the motor off to realize some fast cool down times.

Yes that is one of the good things if you plan on making a lot of passes at the track especially if they are back to back. But if you don't plan on doing a lot of racing with it I wouldn't bother.
