Mmmm I like competition! I doubt to see the results before mine so it will be a blind contest :)
Three months is not long enough for a system with all copper, but a mixed copper and aluminum system will achieve galvanic corrosion much faster in my experience. for example, when I first started my move to koolance products it was done by testing much of their stuff with allot of my custom milled copper blocks I made in my shop. The results of running water, a bare aluminum rad, and copper block where horrifying. I couldn't believe koolance was peddling this crap to people. However as I started to research their products more I realized that they don't intend their stuff for use with other manufactures stuff. All koolance product used in a koolance system will perform better because they were all designed to work together. I still think koolance just needs to make their stuff from copper and brass so their stuff can be mixed and matched without the hassle of corrosion. So when I tested an all koolance TEST system the performance was better and corrosion didn't start to Appear till about 19 months. However this was due to the old aluminum fittings and copper blocks nickel plating stripping off at the threads exposing copper and aluminum at the same point and corroding... BOOOO!
So, back to my point, at three months running a mixed mettle system I should see galvanic corrosion and I am not. It is proof of the fact that nickel plating is great at preventing corrosion. This is why allot of industrial companies use nickel plating on their machines, to provide a long term protection from corrosion. I will however post it in the forums when it finally does corrode, and why it corroded. Given the fact that I am using the new nickel plated brass fittings from koolance I won’t be having any problems with them causing the corrosion. Right now I am watching the Koolance Aluminum rad and D5 top right now to see how durable the nickel plating is. I never said anything about steel beings used in my loop. The only thing I said is that galvanic corrosion will happen in a system despite the metals being used given time. The whole point of my post was to argue that nickel plating all your metal components like koolance does, will help to prevent galvanic corrosion especially when combined with a cooling fluid with strong anti corrosive properties. I will say this; Koolance should have made that D5 top from Copper and not aluminum. So I will grab an extra koolance D5 top off the shelves and go about reproducing it with a copper block and then nickel plating it. I will have to make a custom mounting bracket as well to handle the extra weight of the copper. For Shidzfa and giggles I will make the mounting bracket multi angle adjustable for mounting in different systems. Might be able to sell it in my shop. Should take about a month to produce, I'll keep you guys posted.

First off I would never trust a woman with anything... Second the quality of the nickel coating is actually very good. Koolance uses a Phosphorous Electro less Nickel plating which offers excellent resistance to alkaline corrosive environments. This is an industrial standard and I have allot of machines in my shop with just such nickel plating. The point being that with this nickel plating prevents corrosion for the duration of the coating. Given that the only thing coming in contact with the nickel is liquid coolant it will last a very long time. However that’s not talking into account that something ells might strip the coating off like the constant removal and reinstall of threaded fitting. This is actually how my first koolance test system corroded. The aluminum fitting and copper block lost the nickel plating from constant friction. But at 19 months before that not a single bit of corrosion occurred and probably would have stayed that way had I not fiddled with the fitting so much. I am now using Koolance’s brass fitting so this won’t be an issue anymore. Taking risks is how we learn about new ways to do thing so YES I would take that risk, but I can also afford to do so. I have more trust in nickel plated copper and brass systems than I do in nickel plated aluminum and copper systems but if you take good care of a nickel plated koolance part it will work as intended.
:horse:
Well said! I don't trust women or Koolance. The reason for not trusting women are obvious. Koolance has lost all my respect since the infamous radiator test about a year ago (I really don't know if radiator test is the right term, maybe I should call it jet exhaust test...? ;) )
Hear, hear!!!
they are starting to... hopefully they can fast forward this, and also cut some cost, their prices for those alum kits is quite high...
I end up testing alot of pump top prototypes behind the scenes for different people. Many times they are just incremental tweaks towards a final production.
Pretty simple, they send me a top, I test and play, I send them the results, then they decide if/when they are done with their design and ready to go public with it.
I actually have about 8 different prototype tops sitting here..one of the few testing perks..:p:
So.... would a D5 with a top be better than a DDC 3.2?
Edit: Theoretically speaking, of course.
My test are showing that this one http://www.modreactor.com/gallery/al...s/10526/d5.jpg
makes D5 to be as good as DDC-3.1 equiped with the best custom top.
And as you see this is a prototype - it has margin for some minor tweeking.
So IMHO D5 will be very close to DDC3.2 with custom top and will beat it if a modification of the impeller is applyed.
I think EK's is very ready.
Have a look in Martin's Sig :D
were chasing after the 3.2 not 3.1.
and if you have to undergo an impeller modification + Top.
bah.. i'll keep quiet.
:T
Its just the D5 wasnt designed for what you guys are hoping for. But no one needs to listen to me.
It was said a while back, the whole point of the top was so you can use barbs. Very little performance gain was theorized. But as i said, well let martin test. :T
Were just seeing a lot of hyped DejaVu again. This is what im trying to say. :T
But oh wellz.
Dont get me wrong, id like a top too. Having the ability to put barbs on a D5 is awesome. But im not holding my breathe on the performance area being revolutionary like the DDC's top vs no top.
Looks like another clean exit spiral design, very nice.:up:
You might experiment around with constructing an inlet nozzle like the old DDC2 stock tops had. I think you've pretty much done all you can with a nice clean spiral exit and sharp cutting edge (Short of maybe making the cross section round vs square), but the inlet might have some pressure tweaking capabilities.

I noticed the smaller inlets really helped pressure on the DDC tops and I think these nozzle/lips help better seal the inlet/outlet. The D5 inlet is huge, so you might be able to do something with that. If nothing else you could just experiment by custom fabricating a few barbs with little nozzle extensions.:shrug:
