Meziere H20 pump - worth it?
I'm considering two options for the top end package...
- Install brand new GM water pump
- Install Meziere electric water pump in existing housing
Is installing the Mez a complete PITA or is it worth it? Which would you do if you were doing it? TIA! :)

I installed a H/D Meziere when I did my heads/cam upgrade. It is really easy to install if the timing cover is already off, and it really makes the car rev smooth.

FWIW camaro guys have been having all kinds of problems with them and overheating.
their advertised life (which is inflated in my opinion) is much shorter than the LT1 waterpump.
(i dont know what motor you have)
Most agree
its not worth the 7hp in a daily driven car
edit:
you have an LT1 :)
well you have my two cents :)

I've been running one for over a year and a half with no problems at all. It allows you to use any timing chain you want and eliminates one major point of failure on the optispark. If the meziere goes it won't puke on your opti.
In fact just the other day it potentially saved me some trouble. Apparently I was too stupid to get the proper mix of antifreeze in my car last and it froze! It didnt' freeze solid, but it got real slushy. Instead of having the mechanical water pump trying to turn this and potentially breaking something the meziere just blew it's fuse.

For every person you can find who's had trouble with the meziere you can easily find one or more who hasn't. From a lifespan standpoint I don't think you can honestly call it any more or less reliable than the stocker. I know lots of guys who run them locally and nobody has had the first problem out of them.
You can argue the point all day in both directions, there just isn't enough data to draw any reliable conclusions.
Personally I favor it for several reasons, the least of which is the hp gain.

Re: Meziere H20 pump - worth it? (cprgmr)
well just so you know i'm not talkin outa my rear ;) http://web.camaross.com/forums/showt...hlight=Meziere
there have been countless others
Personally-
i'm getting one-
only because my camaro sees 3000 miles a year IF THAT
and its pretty much trying to squeeze out every last HP too!
Id highly reccomend making some kind of light so that when the thing craps out- you will know!
I think NOMAD has one (on cz28.com)
(search for him and email him or something??)

I read the posts in the link you provided. One good suggestion (and it's something I did) was replace the cheap interference fit connector with a "positive locking" weatherpack style connector.
I think prudence on the part of the installer is key. Some suggestions...
- Check the fit of the pump (you can somewhat adjust the impeller location on the Meziere via a set screw) on the waterpump housing
- Temporarily install the pump (minus coolant) and run it for a second or two to verify the impeller doesn't scrape the waterpump housing when it runs
- Solder the wires together or use weatherpack connectors vs cheap spade connectors
- Install a better in-line fuse / fuse holder
- Use a good relay, not some $7 made in China POS
Be honest with yourself/be cognizant of the fact that if the pump dies you're on the side of the road.
:cheers:

The only thing that scares me about having an electric water pump is just that. It's electrical. If the fuse blows and you don't have some sort of warning light you wouldn't know until you started overheating. I think for the HP gain I will stick with a mechanical one.

Re: Meziere H20 pump - worth it? (cprgmr)
Thanks for the replies guys! :cheers: I understand that there are two Meziere pumps you can use:
- A replacement pump that installs into the stock pump housing.
- A completely different pump that looks like a '[' with the pump in the middle.
Can you use either or does the second option stick too far off of the engine (causing front cross member clearance issues)?

This is the only Meziere that can be used with the LT1.

cprgmr, if you are going to buy a Meziere, get the heavy duty one, it is only about $15 more.

Like this warning light. http://www.akmcables.com/mezinst2.jpg
Not yet, but Saturday I am going down to R-D Racing's shop and Dave is going to use my car to build a prototype camber-brace that will work with the Meziere.
