Looks great, can't wait for the final results

That dual pump is sexy as hell :slobber:

Hey fellow Bimmer guy... good guess but that's actually an 06 E64. Only mod so far is an LED light-source upgrade for the Angel Eyes so they match the color temp of the Xenon HIDs (stock Angel Eye source is incandescent).

Those are actually sealing washers, they have an inner crush ring of plastic. Here's a pic from my worklog-in-progress:

:slobber: :slobber: (drooling is an understatement)

I really love the looks of that car

is that the cabrio or the coupe??

I wanted to order some fittings from them but the shipping was like 50 euros. Is that what it cost you or were you able to get it cheaper?

BTW, your rig looks great. I'm not a fan of external rads, but overall it looks sexay :toast:

WS - very nice, clean setup. Keep up the great work! ;)

I have been looking into combining AN fittings with Tygon/Compression fittings in my new build for a while now as i find using jubilee clips over barbs rather ugly when you have a case window.

Do you know if you can use these fittings with existing watercooling tubing of the correct diameter? I will be using Tygon R3400 as am wanting to go for an all black hose and silver fittings look.

ps this is a great source of info for AN fittings - http://www.speedflow.co.uk/helppage.htm

Nice use of automotive components and nice implementation. Sorry I'm not much of a BMW fan, but I congratulate you nevertheless.

I am in love.............:p:

Nice work, and can't wait to see her complete.

I just want to ask, if you don't mind, adding a couple of pics of your Rig to the STACKER SLACKER thread, be it that you have a Stacker, and a sexy one @ that.

The fittings for the water blocks are G1/4 to -6 AN adapters, which are almost impossible to find. I got them from www.kinsler.com part # 8280 (here I am giving away my secrets :) now everybody's going to be doing braided lines).

These are heavily anodized to withstand much harsher environments than PC watercooling (e.g. gasoline, diesel, nitro methane) so I have confidence in the galvanic corrosion situation. Just to make absolutely sure I'm going to be adding some Pentosin.

Well, there is no way to get them at a reasonable price (LOL) but the place to buy is www.summitracing.com. They're almost the monopoly on internet race parts.

You don't really want to know how much this cost :) You'll need a hacksaw with 2 blades (both mounted simultaneously in opposite directions), a sturdy bench vise, various open-end wrenches, hose assembly lube (I used water-based lube from an "adult toy store" to avoid getting grease in the loop), and various fitting adapters.

The first billet reservoir I got had 3/8" NPT taps, but NPT doesn't look that great with the tapered fitting sticking half out of the hole, plus I hate teflon tape and all that crap, so I got this Billet Specialties power steering reservoir which uses AN straight O-ring boss taps and also has a nifty slotted tube on the intake to prevent frothing (which if you've ever worked with Laing pumps, you know is a very handy feature).

WS

Thanks. A couple more questions...

Why did you choose the -6 AN vs. -8? If I understand correctly, the -6 is equivalent to about 3/8 whereas the -8 is about 7/16.

How flexible is the tubing (can you measure the minimum bend radius/diameter)? and how easily does it kink on tight bends? Is that bend from your CPU to your GPU about as tight as it will go?

When you cut the tubing, how easily does the stainless weave fray? I assume if you are careful, you could put the tubing over a normal water cooling barb and clamp it before it frayed beyond repair?

To be honest, I've been looking at stainless-steel braid sheathing for my tubing for a few weeks, but it would be ideal to find some pre-braided hose instead such as the summit racing stuff you are using. I can't justify the fittings (as nice as they are) since I have two loops with 18 terminations in total, it would be rediculous.

Any thoughts on this?

hmmm.. high reliability.. i think not. while this project surely looks cool, the use of aluminum in the fittings is about the worst idea you could have. As soon as you screw them into the blocks, the anodization already starts to wear off.

Is that res stainless steel or something? And I'd be pretty scared of the aluminum fittings...

Other than the aluminum it looks great. That is really unique!

he already said it is highly anodized aluminum, hence the use of the extremely nice car parts. if you guys read his post you would know what you are talking about

AFIK DDCs are some of the most unreliable pumps, even in series or parallel, this cheap plastic crap just isn't something that you can trust to leave on for long periods of time...

DDC, D5 both are not reliable. Hence the DOUBLE pumps ;) The chance of both failing in a given period of time is tiny.

True but, with double the pumps comes twice the odds of failure.

Odds of failure? When he puts 2 pumps into his loop, the goal is to A. get more performance/satisfaction B. act as a failsafe. Because the water will still be circulating with just one pump working, we take the probability of the pump failing at any given time, as the probabilities of each of the pumps failing multiplied together. Each pump has the same chance of dying, but you have 2 pumps, so yes the odds of A pump failing are 2 times as high. However, the risk of your system overheating as a result of the pump failing are now MUCH MUCH MUCH lower. Not to mention, if a pump happens to break, you can still use the other.

actually the probability that both pumps will die at the same time is

1/y x 1/y

You just multiply it. I believe the DDC-2 was at like a 5% failure rate. Dont remember what exact number alex gave.

so thats 1/20 x 1/20 = 1/400 chances both your DDC-2's will die at the same time.

mmmm.... i still prefer my RD-30 which has like a 1/1000 chance of dying :toast:

I did read his post (hence how I knew it was aluminum barbs) and I saw that. Still doesn't mean I like the aluminum ;)

serial knock on wood for both pumps failing at the same time...
