Superflo I/C Pump

I am hoping my IC pump is shot (another story altogether)...

Anyone familiar with this pump (link below)?

Sources tell me the Superflo the best option for the 113K.

Sources also tell me that the Mez pump is low pressure/high volume and even when they are working up to their potential aren't sufficient for a modified 113K.

Thanks,
TK

That is a pierberg CWA-100. It a great, high flowing pump. It is essentially the same pump used on all newer AMGs (with a different connector).

I have compared that pump head to head with the bosch 010 (and the peirberg CWA-50) and a couple of others and it is by far the best flowing pump for the money (particularly when measuring Flow at typical charge cooling system resistance).

After testing various pumps, the CWA-100 is what I ended up using on my SL55.
I would not hesitate to get this pump from VRP it is a very good price for a great pump.

hope that helps,
Chris

attached is a graph comparing it to various pumps. I did not create this graph, but all of my testing on various pumps, agreed with it.

Latemodel21,
Thank you! Over the top response (you are too kind). Hopefully I am not pushing it here but do you know if the pump can be set-up to where it is continuously running?
Thanks,
TK

Yes, it can be set up to run anytime your key is on, etc.

Keep in mind that this pump pulls about 8 amps (8.4 at start up and 7.2 to 7.35 thereafter in my testing) which is more than twice that of the 010. SO, you will want to run heavier wires and fuse it at 10 amps or more (I use a 10 amp fuse; mercedes uses a 15 amp fuse in newer cars that run this pump) .

hope that helps,
Chris

"Yes" and "Big time". Assuming I will have to do the same thing when I add a trunk tank with Mule pump (?).

When it comes time I will show you how to wire up a relay to ensure proper power with no issues.

Install is complete but the car is still at the shop and trying to work out a few "bugs". From what I gather it flows excellent and was set up to run when the key is in the ignition!

A relay was used with heavier gauge wire to pump and battery point at front SAM. I believe stock wiring triggers the pump.

Do you have to use a heavier gauge wire and fuse if your just plugging it in were the factory location? Using the VRP pump.

Yes you need heavier wiring. It takes 7-8amps, much more than the Bosch takes

So how far up do I need to run the heavier wire? Example, VRP supplied the pig tails. I basically cut the factory plug and wire it in at that point with the pigtails that the pump supplied with.

You would run the heavy gauge wire from pump to relay. At the relay you would run one heavy gauge to the battery power, one smaller wire to ground, and one wire from the original IC pump as the turn on signal. Ground the pump with heavy gauge wire (same size as power wire) no farther than 18 inches from pump.

That help?

Hulk, For all it matters it replaced a Mez pump...

Thanks for the advice on the heavy wiring.

Also, "Chiller Killer" is fixed. Wasn't the KC. I had leaks coming from my a/c lines. it was 68 today and rolling IAT's dropped as low as 48. Did a few pulls to unsafe speeds and IAT's went to 170 range. The shop is moving the return line to the back of the engine bay tank. Hopefully that helps. As far as the wiring goes they will have the S/C off sooner than later for a few more "goodies" that should rid me of any IAT issues (even with a 225 crank and 50 FSP set-up)...

225/50 is an exaggeration but you guys get the point.

Mez is a low flow pump big diff. Also you need a pickup line in the bay tank. If you took that out you will have issue

Anyone have a pic of where they mounted? Everywhere I try to stick it hits the PS hose.

@hulk - i know that the cooling fan has a direct connection to the ECU. My ECU got all screwed up where the cooling fan was turning on as soon as i turned on the car. I found another thread that helped me diagnose this issue. Without the heavier wire and larger fuse, would this have caused the ECU chip that controls the cooling fan to "short circuit? have you observed this or heard of anyone else with this issue?
