The CWA100 upgraded supercharge coolant pump thread...everything CWA100...

[Shuga]

So all 3.0T’s or?

[bajan01]

Over the weekend I logged some data...

At 66F (~19C) ambient I ran 3rd from about 2k through 4th and halfway through 5th (SQ5, ZF8 trans). IATs started at 32C and maxed out at 58.5C. This was after a similar pull a few minutes before that maxed out at 57.0C. The recovery time is very quick with the 57/203 setup and the CWA100 pump. I also logged all the PWM channels that showed percentage and the PWM is most certainly controlling the pump. I’m not sure that I need to do the pump mod to have the pump running at 100%, but I might just do it and gather some data anyway.

Anymore more observations after running a couple days now?

Highway cruising IATs are consistently 6-7C above ambient. I am going to try and get some current readings from the pump as it cycles...wish I did that with the CWA50 pump but too late now.

I cruised today at 60mph ambient was 90F and iats are 14C over ambient with CWA-50 with the pump mod. Meaning that the CWA100 helped you with 7C over a CWA-50

When I say “highway” I’m talking 80mph. At 60mph I’m probably closer to 10C over ambient at 85-90F. I’m also at 57/203 so I’m convinced that there is an advantage here.

Mine probably was 70mph

Anymore observations on the CWA100 vs CWA50?

Any thoughts on this: https://www.dormanproducts.com/p-859...ump&origin=YMM

I realize the connector is a 2-pin (power/ground), but the data I'm seeing points to this being a replacement for the same Mercedes as the Pierburg, for 1/3 the cost.

I wouldn't use it without testing. Keep in mind even the cwa50 pierburg tends to outflow the majority of aftermarket pumps out there when you add head pressure. Before you do the dorman id at the very least run it on a test rig against your cwa50. The fact its a 2 pin says its not a replacement pump for those applications as well.

I’ve seen IATs down to 5C above ambient but typically I can hold 7C above ambient at 75-80mph.

Sorry in advance for the lazyness,

I believe I've read that the seller (or a member here) was working on providing a plug-in adapter, is that available? I would rather have my shop install a plug-in play mod than having to do wiring mod.

Thanks!

[lclercaudia8]

hi guys where do you find the pin for the 3 pin connector ?
i order the 4 pin for the CWA100 i order the 3 pin connector but in the 3 pin i haven't pin inside :)
thx

Not buying a crimp tool I’ll borrow one from work

I'm looking for the cwa50 plug to plug into the stock harness on a S4. Anyone make that?

Just ordered cwa100-3 with cwa50 to cwa100 harness from Tecomotive for $292 shipping to USA included, using 5/20/19 paypal usd/eur exchange rate. Thanks to all of the early testers for all the info.

I ordered one too. I have been taking with them for the past week. Let me know how yours works out

[Shuga]

So once again this works for all 3.0T’s? Or just the S4s?

I wouldn't conclude better until you do WOT and watch recovery

0-130mph WOT pull...starting IAT was 33C and ending IAT was 59C, 20C ambient. IATs recovered quickly. 203/57, AMS hx, W/M, EPL ECU tune. Conclude what you want from my data...I’ll send the log file to anyone that wants to see it.

See above, I might have been the first to run the Tecomotive CWA100-3 kit on my SQ5.

I’ll take that as a yes

Bajan01- was it plug and play? What did you use for harness?

Tecomotive sells the harness...100% plug and play with the harness.

[gsxr_wrx]

Sweet. That’s what I ordered from them. Just wanted to verify. Can’t wait until mine comes in. I’m running he APR divorced heat exchanger and think it’s getting little warm,not to mention I have P190D00 code-coolant pump for charge pressure

[Shane Horning]

What do you guys think about plumbing another cwa50 in ? Seems like 2 of the original pumps would do the same thing as 1 cwa100? I'm just thinking that could be a cheaper alternative as used cwa50 go for $50 vs. $150 - $250 for cwa100

[gsxr_wrx]

A new CWA50 goes for like $370
A new CWA100 with harness is $300
Give or take on these prices.The amount of work for two pumps compared to one also. Just my opinion

Got it. Well I got an extra cwa50 so I might try adding it

[waxxonMTL]

I know the answer could be '' just log and see'', but I haven't, so... would you guys think there is any benefit to doing this upgrade if I live up north where 10 months out of 12 is usually below 70*F and I only do ''spirited driving''?

Money is not the issue, its more like I'm not certain I (and most people living in the north) will benefit from this mod. Thought?

[gsxr_wrx]

Anyone know the procedure for swapping pumps? Bleeding process or just swap pumps and start it up?

[bhvrdr]

Always do a quick bleed when you create the potential for air in the system. Sc cores are my highest point so i crack those bleeders.

[gsxr_wrx]

So just put the hoses on for the new pump and open the SC bleeders? Anything else for the pump? Priming it? Sorry for questions ,don’t want mess up anything

[bhvrdr]

Swap the pumps out. You can pinch the hoses for the swap over. Probaly will just lose a couple ounces. Run the car with the pump on circulating fluid. As the fluid comes up to temp and engine gets warm crack the bleeders one at a time until you get steady fluid coming out not froth.

[gsxr_wrx]

I Appreciate the help

[bajan01]

I Appreciate the help

You will ultimately have some air stuck somewhere and the factory reservoir level will drop a bit over the following few days. Crack the bleeder screws a few times over the following few days. I have a few extra bleeder screws on hand as I have broken one before as they get brittle as they age.

[gsxr_wrx]

I have a divorced heat exchanger,does that make a difference with bleeding the system ?

No.

[Adamantium]

Are the dimensions of the 100 identical to the 50? Ie. Direct swap with no mechanical modifications?

[gsxr_wrx]

They should be. And you have to get the plug N Play harness. Mines on order, should be here in a week or two

[bhvrdr]

Yes the housings are identical. They both fit in the same bracket.

[bajan01]

Agreed...
