i like the left one
Please for the love of god let it have some tweak to give it some proper head presure
I've been meaning to try the OClabs top, the left one. It's the cheapest decent DDC top. I don't know if I like the new design, the barb area seems fragile. That's the main thing that bothers me. The channel is bigger, so that'd be an interesting thing to test...
Rain water will move faster around the globe than out that new top! I agree the barb fitting looks too risky.
Yes there current top is by far the cheapest going on the merket you can get but it's not as good as the Petra 01s which really gets the pump working to make power
pump + top
P.S.
i'm going to suggest a crash test!
Sexy, hmm, that looks like it's a stronger plastic than acrylic? It seems it's been molded rather than machined.Originally Posted by Gioz

looks like a molded top(like stock but with proper barb placement) also looks like the pump housing to impeller clearance is allot tighter(head should be real good as long as the inlet/outlet isn't too big) cant wait to see test results

so the outlets are 1/2" ID?
Hello to everyone
Here is the first "quick" test results:
PlexyTop (~0.43bar): http://www.oclabs.com/res/articles/1...ddedclosed.jpg
XPTop (~0.46bar): http://www.oclabs.com/res/articles/1...ttaclosed1.jpg
That's only a little preview, we didn't make any test with DDC350 yet and this is just Prototypes Tops. Probably at the end of next week, we will have here the pre-production samples and after the new test (mechanical resistance, flow rate, pressure, etc...) we will pass to the production XPTops.
The barbs hose are 1/4Gas BSP and the tops is a Mix of alternative and CNC production to pass over the mechanical CNC design limits.
Here is also the Preview link: http://www.oclabs.com/particles.php?docid=1323
Kind regards, Nikos

It all most looks like glass!!!
I still say the outlet is way too big Nikos.
they look pretty. prettier with some metal high flow barbs...
The left one was a nice project but now it's out of production since April and will be also definitely going out of stock this week
+0.03bar ~ +30cm
Yes, it's true, it's the cheapest Top because I have decided to make it the cheapest one and this new Top probably will have the same price for the base version and something more for the UV reactive version.
About the fragility of the lower barb, be sure that this new design will be more resistance than the actual CNC top (left one on the pics). The PlexyTop material is a high quality "metacrilato", but I ensure you that will never be a better quality material on absolute mechanical resistance as the new acrylic materials that we have already test on this prototypes. The next pre-production samples will be at least more resistance over 50% than the actual prototypes and they will be about 200% more resistance than the CNC PlexyTops...

Stock Top is made with PPS (Polifenilensolfuro) plastic, that's a special plastic material that injected in the machine over 380°C degrees and costs 3 times more than other normal plastics because when it becomes cold assumes some metal properties for industrial use. The material we have used for the prototype was only a quick test to see how was the trasparency effect, the new performances and of course the new UV reactive effect that seems perfect...
Perhaps of the trasparency effect ?
I can change the outlet way in 2 hours of work in the factory if I'll decided, but honestly I don't think that I've to change something as I was working on this project over three months to reduce vibrations and noises. I don't want to make the XPTop have 1% more head pressure than now (+0.03bar Vs PlexyTop) and breaks the DDC motors every week. My point of view, it's to design always a trusted product that will give 100% warranties to the customers, not a Dragster that brokes the engines on every pass.

Nikos this guy thats tested all the tops said that Alphacool was best which is a load of crap.
I have a Petra 01s here, i've one of yours coming and a Alphacool.
I'll clean them all up then i will do a test with them.
I can test it on 3 differnt pumps
The newest DDC that us in the EU have, the one that can be modded to 18w.
I also will have the most comen version in the USA which is the orange 18w one.
I'll put my hand down that Petra will win, followed by the alpha cool and then yours.
If you look at the Petra one you can see the outlets sizes are way smaller than your which increase flow and presure.
I guess we'll see what i find but i will also measure with some digital veriner claipers to show it all off
Petras top doesn't give both more flow and more pressure.
If it ain't watercooled, I don't wanna know.
^ Petra 01sWith an 18w DDC
Max. Head Pressure (at 12V): 8.2 psig (18.91 feet - 5.76m)
Max. Discharge (at 12V): 4.11 GPM (246.6 GPH - 15.56 LPM/933.5 LPH)
^ STOCK 18w DDC top18w DDC
Maximum Head: 20.2 ft (6.1 m)
Maximum Discharge: ~ 120 GPH (454 LPH)
Goves it more flow with a decent amount of head presure where as this OC lab is just flow flow flow no proesure there at all.

Not according to OC3D when used in a loop it doesn't.
Which version you talking about? The s version?
If I were to create a DDC top with the outlet hole the size of a homophobes arsehole with his but cheeks clenched together, which created highest head pressure but killed a load of pumps, would I get a cookie?
If it ain't watercooled, I don't wanna know.
If you look at his test to every other there all over the place and the ALphacool for fact does not perform like he says!!!
Yes i did say 01s but even the 01 does better than the oc lab and alphacool
Pete you can modify pump characteristic(pressure/flow) but it need some choices.
these choices can make it best or worst top,cheapest or most expensive,nice or similar to the original...
if you don't know those choice you can discuss around what you think about aesthetic or preview statistics,not discussing regard all project/product spec.
i suggest you to try what you want,to study what you want and eventually to explain your point of view and your test,but i think you should not explain your conclusion from an image or an absolute value (for example maximum head pressure) reported here because it's not so important to know a point of pump characteristic but i think it's important to know how pump characteristic changes in various real application and that' s impossible to see from actual preview.

Storm need presure not flow
SO does every other block going
The OC lab only did well on flow from what i remeber.
Nice clean simple block it is, just need that twsit but there are other factors which are putting me off ever running it which i don't think Nikos is awear of at all
Pete if maximum head pressure is higher or lower than another top,it does not mean that the pressure will be lower or higher in some application,it depends by pump characteristic...and i think you don't know it because it's not published!
Hello to everyone
Today we've try all the necessary "crash tests" and I'm happy to say that everything goes OK. The new material has not only seems to be more resistance than the SAN (StireneAcryloNitrile) we've used last time, but has demonstrate that is over three times better. There is absolutely no cracks or risks with this new one, either for the screw holes and the horizontal barb area
Here is some preproduction pics:
Kind regards, Nikos

looks nice
how much are these tops
from the looks of the geometry of the outlet tube meeting the volute, I get a feeling that the performance will be lacking compared to alphacool/petra
i calculated that to 5.67 feet of head........
if i am wrong i am sorry, but are you kidding me?
