First off my Z is not a daily driver , but it is driven bout 75-100 miles a week . Can I run a CSI or Meziere pump on a car that see's limited street time . My other option was the Evans NPG cooling system using propylene glycol . What are your thoughts on this .
Thanx

they flow 30 GPM so it should work in that respect. i wonder about what they would draw in way of current? i have a moroso race eletric water pump and was thinking it said not for street use, but i can't find the paper now and don't remember why it's not for the street.

I've done plenty of research on this and let me tell you what I know...

1) I have a Mr. Gasket electric drive water pump and I think it's fine for street driving as long as you're not lead-footed. The thing spins at 1500rpm constantly so it's really more practical than some think. (I think this only works out to 15gpm) When I used to drive my car more than once a week, I saw the temp rise above 200* once (this was in 90* heat remember) and I just flipped on my fan and back down it went to 160*. But for people that like a little bit more speed, more often (like myself) I would suggest a full fledged electric pump.

2) The best (Edit: belt-driven) water pump flows at the most 28gpm the last time I checked, but I could be wrong, so don't jump all over my case about it.

3) The CSI electric pump you mentioned is a nice unit and a lot of 4th gen owners use one and they get a decent gain in power, but don't expect a whole lot. There was a website with actual numbers, but I've lost it. But in my quest for total cooling I've come across a pump that in much better in 2 respects.

4) Aerospace Components makes a billet water pump that flows 37 gpm and only draws 4amps! I haven't read about a better pump anywhere and here's the greatest part...the CSI pump only flows 30gpm, like Ede said, and it draws 5.8amps, but it costs $10 more than the Aerospace pump. The Aerospace pump costs $250, which is a lot compared to a normal belt driven pump, but the advantages for me seem well worth the extra $100.

Aerospace Components also offers a pump that is remote mounted which is perfect because then I won't have to make custom brackets for my v-belt since the pump won't get in the way. Whenever I get my new motor built, this will be the way I cool it.

That's my $1.02 anyways

oh yea, jeg's sells the pump.

Thanx alot guys . I'll definately look into the Aerospace unit
Then I'll have see if I can still use my serpentine . I already have the smog pump gone and bypass the power steering at the track . Hmmm...it might work.

 

One more thing to consider about electric pumps. Electric motors do wear out reguardless of what kind they are. As a daily driver, a high end pump would be the most desirable since it would be designed to last for a long time.

Water pump drives such as Moroso's is just a 12v furnace motor driving the water pump. This motor is no different than electric fans or heater fans. They do wear out and if it does on a street vehicle, the engine will definetly overheat.

The high end pumps should have a sealed motor incorporated into the pump. It also will wear out eventually but it'll take a lot longer.

You need to get one that will handle long periods of street driving at variable speeds. The Moroso pump drive isn't designed for this. It will work but not as efficiently as better pumps.

The main reason I use a water pump drive in drag racing is to help cool down the engine between rounds. Electric fans just cool the coolent in the rad when the car is turned off in the pits. By removing the thermostat and turning on the water pump, you cool down all the coolent in the system.

I was just flipping through a Summit catalog. CSI just mentions a 1 year warrenty. Meziere gives a 2000 hour seal life expectancy. Weiand states "for drag use only"

Unless you need some reason to run the pump when the engine is off, it would be better to buy an aluminum water pump. Electric pumps only pump at a constant speed. At least an engine driven pump will pump faster as engine speed increases. I think that's why the Moroso pump isn't rated for street use. Sustained high engine rpms will produce more heat than the pump can push through the cooling system.

When you guys say high speed what are you talking about? what RPM range? I'm concidering getting an elec pump for my 305, which durung the summer is a daily driver. about 1,400 miles a month. I'm looking to it for power advantages. Right now is basically a stock 305, but soon i'll be replacing the heads, cam, headers, just thought the elec H2O pump would help in keeping the power i want to create, question: is is feasable? worth it?
by the sounds of it these things can't take much.

btw: i do like to push it some, but it generally stays in the 2-3,000 RMP range

Meziere has electric pumps for street use. They are the best out there. Rated at ~2500 hrs.

I'm not going to bite your head off but electric pumps cannot compare to belt driven pumps at all-no way.
The best belt driven pump in my opinion is made by Stewart. Their lowest priced stage 1 pump flows 100 gpm at 4500rpm and is only around $60. Check out this comparision to the Edlebrock pumps.
