Meziere WP136s or Johnson CM30 Pump Which is best
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.

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.

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.

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?

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
