I am running a metziere 55gpm pump. I bought the style that comes with a flange that you weld onto the radiator. I run -16 braided lines.

so far so good.

 

I mounted it on the passenger side frame rail almost directly under the compressor housing.


Up close.

 

Here is a lot of good information on the pump I'm using.

U not worried about excessive amounts of radiant heat from your headers ?, doesn't plastic melt when it gets hot ?

 

The manifold, turbine side of the turbo and downpipe are jethot coated. They are also exhaust heat wrapped and I have a heat shield there now as well as a vented hood on the way. It should be alright.

 

I should have mine in hand on monday , it is going where the a/c compressor used to be , right under the power steering pump , I'll get some pics up when I'm done.

 

OK , got the pump , mounted and wired it up ,now I just need two -20 AN swivel fittings , one 90 deg and one 180 deg at a great price ,( those fittings are really expensive !!!) can anyone help?

 

I might have a few, I'll check for you. I've got a bunch of straights. And no, they aren't cheap. I've got 6 of them on my the coolant system setup alone.

 

OK lemmie know.

 

I've installed my EWP , now my "small" alternator belt is too large , anyone know where to find one to fit just the alternator and main pulley , with the alternator in the stock location ?

 

I just want to thank everyone that has added to this thread, it has been on of the better reads on here

I have been reading alot about using a EWP, now i am going to use the Meziere one, and to toss a wrench into this hole think, I will be running Evans coolant with 0psi on the cooling system, With this setup i gain everything and dont have to worry about another blown Coolant seal.

Thanks agian

 

Anymore Info in this great thread

 

Just a heads up if you plan on using Evans with an EWP you're going to have to use NPG-R due to coolant viscosity issues.

 

For anyone who might be interested , Meziere now makes a pump that incorporates a thermostat controlled bypass !! , http://www.meziere.com/2007_catalog/28.pdf.

 

BMW is now fitting their latest 3 Series with Electric Water Pumps, and since it's factory kit for a street driver car, it should have good long term reliability.

Anyway, here is a cut away promo shot of it.

 

Bmw = Mucho $$$$$$$

 

how does a EWP affect/improve your idle/off line power as it reduces the drag on the engine at low rpms?

Does it tax the alternator? I'm thinking about this for my RX8 in the future, but I'm going to be running all the other accesories (A/C, Radio / PS etc....)

I really like the idea in theory, and with this on a Renesis, the only thing driven by the engine would be the alternator and A/C

 

First impressions, : the new KOYO NFlow radiator is BEAUTIFUL ! , its well made , has a bleed on the top tank , is tripple pass and even smells nice ! , this rad together with the EWP kept my coolant under 190 , no matter what ! , I decided to try it without the thermostat to see what would happen ,....well it takes a bit more time to heat up , but it doesn't go past 185 ! , and remember this is with a big 4" thick intercooler un front of it and no ducting (yet) ! My idle speed has increased about 150 rpm , pull off and speed changes seem smoother , but I cant say for sure as I have been doing some tuning too .

 

I don't have enough real world use with it to tell you. Lots of the guys down under run similar setups for years without a glitch so I don't imagine it would be any problem.
My setup doesn't have PS, A/C, Radio, etc... so I wouldn't be able to help you much on that front even if I had more hours logged.
Sorry.

 

Here is some more good products for the thermostat problem

Meziere inline thermostat http://www.meziere.com/2007_catalog/29.pdf

EMP electronic controll valve (what I use in my setup). I have a prototype valve, and when I bought it none of these other options were available.

I went with the Stewarts EMP pump

Here is some pictures of the install, also i am running Evans NPG-R

 

Interesting.. I wonder what the flow rate is?
