SWC DDC TOP comming up - tests prove better than Alphacool, DDCT-01s, XSPC

[Sugar4o]

Where will we be able to buy one in the US?

If tests prove that it’s better than stock top it will be available worldwide as DDC one.

If tests prove that it’s better than stock top it will be available worldwide as DDC one.

Even if its as good as stock Id be happy I just want to switch to 3/8 barbs, possibly compression fittings.

[madmaxx]

i'd like a couple UV blue one's

[Sugar4o]

The interesting part is still to come!
When the SWC D5 top is complete we will have a real battle – DDC vs. D5. The two pumps will have tops with the same geometry and the only differences will be:
1. Impeller’s geometry
2. Power - 18W (4500 rpm) vs. 24W(4800 rpm)
So which pump will win?

[Jimmer411]

Hurry up with the testing.... The wait is killing me....

I still have a Liang D5 vario, sitting in it's box, never used.... It sure could use a new toupee...

IMO, the MCP355 will still be KING

You will think that right up until a DDC dies on you

[Sugar4o]

It is official now - SWC top has been tested by Martinm210 - look forward getting more details on http://www.martinsliquidlab.com/

Nothing there yet...11:33 PM Beijing time. :-(

[NaeKuh]

everytime i see this thread.

i keep thinkn sidewinder computers for some reason.

i keep thinkn, omg gary is trying to become like alex?? :O

[NaeKuh]

LOL... We don't want that...

alex does enough crazy things as it is.

LOL cuz of alex i was all my fans under water.

I have the test results from Martin, but I don't want to spoil the surprise
He is very busy lately so give him some time to update his site with the results

[Martinm210]

I'll update my page following this.

Here are the results of the two prototypes I tested. Keep in mind these are just prototypes mostly hand made, so the final product will likely be different.

I tested two prototypes and this is how the better top performed with two different barb setups.

First a side by side of the two tops. The blue version was the same as the clear, but had a shorter volute depth, so tolerances were very tight to the impeller. This blue top performed best. D-tek barbs were too long for the protoype, so I had to use a barb spacer common to graphic card blocks.



Testing:


Up close testing in progress: Note the very sharp blue cutting edge and true spiral volute throughout..nice!


Comparison to the XSPC tops. The red curves indicate high, medium, and low restriction curves


Details of the best test (blue top with D-Tek Barbs):


Overall the best top with D-Tek barbs performed extremely well. It roughly tied the two XSPC tops in an average restriction system. The XSPC tops performed slightly better in high restriction systems, and the SWC top performs slightly better in low restriction systems.

I really like the volute shape on this top, it has an extremely sharp and efficient cutting edge and clean exit, very unique in design as well. This top produced an efficiency curve that peaks out at nearly 25% at 2.4GPM...Great work!!

[The[R]eaper]

wow the top looks great and performs on par with the xspc tops, nice.

blue or green... blue or green.... or maybe red... i dunno.

Thanks martin as always and great job on the top there sugar4o

[Sugar4o]

Thank you Martinm210!
As everybody noticed by the results the XSPC top beat me only at 1.0 GPM with 0.13 PSI and mine is better at 3.0 GPM with 0.26 PSI. And this was expected, because the models tested do not have inlet nozzle so using the D-Tec barbs gives inlet of above 10mm. And this is cured in the final version
The XSPC ResTop is a very fine peace of engineering and I’ll do my best to beat it when a reservoir option for SWC becomes reality.

But first I will please the D5 owners

[skinnee]

But first I will please the D5 owners

Yes please!

[WoZZeR999]

GL, and I hope the D5 does as well as the DDC (because I will be buying 3 soon)

Sorry but I noticed the XSPC Res/Top combo beating your best top from 0 to 2 GPM as the graphs shows.
We should know that most of our setups are in that range, so the XSPC still is the best

[Mord]

the XSPC Res/Top combo beating your best top from 0 to 2 GPM as the graphs shows

Please read carefully!

this is cured in the final version

[leo_bsb]

Please read carefully!

Oh, OK, so we are waiting for your version of res/top combo.
Right now you manage to match the XSPC top on 2 GPM, great result so far

3 GPM is so unreal you must forget to compare those on that flow.
Just make a simple loop preview with martin's spreadsheet and you will notice that.

nice!

looking forward to your product, hopefully in UV blue

[Sugar4o]

here is the first prototype of SWC D5 top

This one performs as good as ddc3.1 with SWC DDC top (this is the only pump I could test it against so far). It has G1/4 threads so you can use whatever barbs you like

I want it!

[CCUABIDExORxDIE]

anything new on this?? it looks really enticing.

[madmaxx]

Sugar4o how's it going with these?

[Sugar4o]

I will test some tweeks on the top this weekend and I'll post mine results. Than a top will be shipped to Martin.
By the end of the next week I'll have my site updated with section for online ordering for both DDC and D5 tops

[Espen123]

This looks really good!

You should make these in POM/Acetal also.

The ring/bolt solution on the 655 that let you choose where you want the outlet, is a good idea, but some mounting holes fixed to the pump body is needed to make this useful.

I think the 655 top is the most interesting, if it performs better than the stock top.

Keep up the good work!



Edit:

EK have a 655 top available also, so maybe Marins liquid Lab can test this one too?
