I was thinking of changing my johnson pump that i have had in the car for little over a year. It hasn't given me any issues or superchager has not shut off at all. But im just curious if the Meziere would be a upgrade or do these two flow about the same any help would be appreciated? I am running a PLM h.e on my car along with a few other performance mods.

I have not seen a Johnson pump, but the Meziere is a seriously nice and heavy duty pump. It's one of those things that lets you know it is high quality from the moment you see and touch it. Not sure of the flow ratings, but my IATs recover pretty quickly after a run (split system, no trunk tank). Not cheap, but many things worth buying aren't either.

why not an OEM Bosch 010 pump? mine works great!

The upgraded Bosch 01 pump is a great pump

yeah i wanted to split the cooling and get a tank but with a wedding in the making not going to happen so fast But the johnson isn't as big as the meziere i wonder what my johnson pumps per min?

i think the oem does'nt pump as well as the johnson or meziere does it?

ill look into that one any links to were they are sold by chance?

All three of those pumps are fine for what you have. But if your going to do a trunk tank later, then keep the Meziere.

Just a well put together dissertation on the facts of charge cooling.
It has my approval,

Thanks hulk ill check it out

wow that is great info Yacht its alot so still trying to soak it all in but thank you on that.

I don't think anyone on here would know the answer to that question!

Cm90 17.2 Gpm
Wp136s 20 Gpm

I Will Buy The Cm90 Off You If You Want To Sell

if your referring to me my pump is a cm30. So the cm90 pumps at 17.2 gallons per min. And the Meziure pumps at 20 which would make it more efficient.

That's my thread.

Comparing the WP136s with any other pump is difficult, as Meziere only quote "open pipe" figures, so we don't know so much about its installed performance. If you look at its size, weight and power though, its obviously a bigger pump than the CM30. Some people have tried both, and all find the Meziere better.

My view is that the CM30 is quite unsuitable for any charge-cooling application, period. The Bosch pumps are better in every way, and the WP136 & CM90 probably better still.

Better buy a Johnson CM90 or EWP-80! CM30 might stop working if counter pressure is too high.

Is the OEM pump running at the certain tempatures mentioned in that thread? Or is it running all the time?

Mackhack

The pump stops working if it reaches 100-105 degree Celsius and you loose the Kompressor power.

Meziere pump flows well real time and blows away those small Johnson 30 magnetic drives , when it comes to real time flow test. There are better pumps than all listed but they run near 1K and some can even be tuned to flow more.

Welwynnick

With IC systems you get a much better indication of installed performance if you look at a pump's maximum pressure, rather than its maximum flow.

Bumping an old thread here, hoping for some advice/experience. During my E63 bumper swap I found that 1) the fuse for the IC pump was blown (and was incorrect at 7.5A), and 2) the PO had installed a Meziele WP136 and wired it to be ON with IGN, and 3) the WP136 appears to be seized/inop. I bench tested it with 12V and there's a slight thunk from it when power is applied, but it does not spin.

I already have a Bosch 010 pump ready to go, but in order to install the WP136 the PO shortened the inlet hose, replaced the wiring plug, and removed the factory pump hanger/clamp. So going to the 010 will take a bit of work (especially the plug part).

I'm running a VRP H/E and considering making it a split system. I've read conflicting info on whether the WP136 is "too much" for systems w/o a large reservoir tank, and the debate seems inconclusive from what I can read. I'm running a 76mm pulley and RaceIQ tune but otherwise power is effectively stock.

What would you choose in this situation? WP136 or Bosch 010?

It’s frown upon to post the same stuff in multiple threats in forums.

I would just swap out with a new Mez pump bc
1. Already wired
2. it’s good pump as mine as been good for 7 years
3. Won’t harm perf for being “too much” and good in case you get a tank later on
