Anybody out there try a Dedenbear fluid pump on the intercooler circuit benz? The inline version looks to be the closest fit. This thing sounds bulletproof.

Keep in mind that people started replacing the OEM pump because it was prone to failure, not because it was thought to be undersized. Now that there is an updated bosch pump many argue that replacing it for increased flow rate isn't helpfull. Perhaps even harmfull if the coolant doesn't sit long enough in the front heat exchanger. There have been discusions about this in the E55 forum.

I'm gonna have to agree with Falcon...Does seem to be a good comparable pump though.

This one might be a good choice to use with the larger, higher capacity intercoolers that Evosport is currently developing.

why dont you go with a Meziere WP136s, it has been tested and proven to work and it is about 100 cheaper. granted you have to drill a hole to mount it vertically.

If you increase the flow rate through a heat exchanger, you increase the rate of heat transfer; that's physics. The output temperature will go up however, as its not a linear relationship. However, the same will apply to the charge cooler, though the output temp will obviously go down instead. Either way, the heat transfer increases, which is what we want.

Don't know much about physics but I do know that if I put a warm beer in the refrigerator I have to let it sit there a while before it is cold enough to drink.

Sometimes I think I waste my breath, I fiited a Johnson CM30 to my 600TT
what seems an age ago, after being given another 100 horses the pump
( which had been replaced 11 months before ) so was probably the newer
Bosch pump, it couldn't handle the extra power. MB fitted the Johnson
the whole thing costing about 200 bucks plus the pump, 150 quid, and now
after nearly 3000 miles she drives perfect, never puts a foot wrong, and the
acceleration is In fact I use it all the time, I still haven't got over
extra power. Money wise this is the best conversion I ever had, K&N next

I agree with the hi flow rate most heat transfer theory, but consider this. We dont run the engines at steady full power, which would benefit from a hi flow rate-most heat transfer set up. We burst the engines for 10 or 20 seconds; in that short time frame maybe the cooler fluid in the lower flow rate heat exchanger gets to the intercooler and for that short time period out preforms the more efficent overall hi flow set up.

The trouble is you guys want to know the ins and outs too much. If it works
and doesn't go wrong just forget it , and enjoy it, It's almost silly to see
a limo flying about blowing everthing away, that's me,

I am reviving this old thread I started. I am ordering the Dedenbear WP3 and a new HE from Eurocharged. Will post a follow-up soon, I hope.

Any opinion on the RENNtech intercooler pump upgrade? I am getting close to doing the ECU and pump upgrade as it seems like a nice upgrade.

Welwynnick

Eurocharged are selling the Deadenbear WP3 as an IC pump?!? They really should know better than that.

The WP3 is an engine cooling pump, and will have the wrong characteristics for IC pumping. Their advertising only promotes the open-outlet gpm figure, which tells you very little about installed performance as an IC pump. There's no mention of maximum head or normal operating condition or minimum flow rate. Plus the current draw is only 3A - that's slightly less than the Bosch -002 pump (which will probably be more efficient in an IC installation).

I really wouldn't recommend using that.
More information see below.

Its a good pump for lots of good reasons, but very expensive for what it is.

Sorry - didn't mean to imply that I was getting the WP3 from Eurocharged. But I had planned on getting their larger heat exchanger and then sourcing the WP3 from Summit.

Call me lazy, call me dumb, call me both. But the likelihood me emerging through the thread you linked with any concept of what IC pump to choose is damn low. Having compiled the data, in your opinion, what IS the best IC pump for the 65 series car?

This morning it was 69* and my car positively scared me. (love it)
Drive around on an average 92*-96* summer day, and the car feels about as inspiring as an SL500. Currently running the '010' iteration Bosch with the factory HE. Pump is functioning correctly and no air bubbles. She will run like a scalded dawg all day long anywhere up to about 80*-85* ambient temps. Creep up 8*-10* form there, and the fun is all over. There has GOT to be a way to address this.

P.S. - found a thread from a forum member who put a WP3 in his 600 (Ithink it was a 600) and he said it was the single best, most effective upgrade he had ever made. Curious.

Sorry for getting a bit carried away on my earlier post, have settled down
I would just fit a new Bosch pump which I have done on my tweaked 65.
I had already bought a new Johnson pump and I had the Bosch pump
which had come off my 600. I done a simple test, connected both pumps
up to a battery and timed which pump emptied a bucket of water.
The old used Bosch took 15 seconds and the new Johnson took 18 seconds.
The Bosch was the newer upgraded version. I now have both for sale.
The Bosch won, so I suppose the rate of flow must be important as it was
designed to go with the V8 and V12 engines.
