yes.... but all of this would only change the AMMOUT OF TIME IT TAKES


i was not measuring this... i am ONLY measuring what is better

Would it? maybe a reeaction wouldn't happen at room temp and it would take a few extra C to set it off?

then i would have to test a wide range of temps because everyone has a different temp... some are even cooler than room temp

The water in my sample is now a dark red, but the metals look exactly the same.

that makes no sense to me. how can your water be havin some type of reaction, when your metal isnt?

I'm not quite sure, I suspect it might be doing something to the black anodizing of the aluminium (even though it looks fine, it might be thinner) or something.

If it's truely anodized properly then I seriously doubt its the anodized aluminum itself being affected. However, dye is used to create the false coloring in anodized metal, so I would have to say it's the black die being leached out of the pores (when you anodize metal, it actually creates pores in the surface. There is an additional step that can be done to close the pores, but it usually isn't done).

DC to have some independent testing.
A quick question to add some confusion in this interesting matter.
Does the Al and Cu touch each other. It's a bit difficult to se in the pictures.
Because if they do it will speed up the corrosive process.
And if they do in some of the tests and not all that will invalidate your whole testsetup and your results.

no touching of the metals, they are just very close to speed up the process.

conductivity through water is an inverse curve.... or something


so what testing have you done, and what are your results?

I'm sorry DC, in my last reply the word "nice" got lost somewhere.
First line should have been:
DC. Nice to have some independent testing.

And no i haven't done any testing my self. So i'm following your reslults with great interest. So don't stop now.

hehe cool man.
well both of the additives do prove to be corrosion inhibitors.
soon i will have to see what the powdery dust like layer is in the PurpleIce tests. PurpleIce may still be stopping the corrosion, but for a cooling system i wouldnt want that weird stuff clouding up my tubes. so redline it is!!!

now just to let the cups sit for a while to see what "grows". i will be borrowing my friends camera and takin some pics any day.

can someone put the Al and Cu touching each other so we can see how bad the och z4 would be?

if metals werre touching each other, there isn't much realavance for the Redline because:
1: redline prevents corrosion VIA WATER between metals.
2: if the metals were touching, they are conducting directly.
3: even the small surface imperfections where water would sit (thermal grease concept) this would simply speed up the corrosion process cause there is a small layer of water between the metals. therefore, the current testing should hold the same, everything may just happen faster (with the micro gap thought).

however, the direct touching of metals has always made me wonder. Anyone ever do any research on direct contact corrosion?



oh and is the z4's aluminum anodized? if so then there should be no corrosion unless it is scraped off.

im new so i dont wanna come out flamin but whats the purpose of this test? u dont ever use 1/2 and 1/2 purple ice or ww let along 100%.....cause im confused are u trying to c how much is too much or what....ive alwaysed used a 30%ww 70% water....

read the post and the web page that corresponds to it
1/2 suggested strength and full suggested strength were used
(2 oz to a gal and 4 oz to a gal)

btw, welcome to the forums! hope ya like it here.

completely off topic, but where do you get Redline Water Wetter? I have checked Autozone, O'Riley's, Car Quest, and Western Auto. I cannot find it anywhere. I cant find purple Ice either. Until I find either one, im running straight distilled.

dangerden.com and alot of others sell redline. i saw some place that sold purple ice, but i found a large bottle online in some corvette store i think.

if your running straight distilled, just change the mix every week or 2. not absolutely sure if that will stop oxidation and corrosion being that i did endurance testing. the copper in my test with just distilled started froming green oxidation just recently.

well, my loop is all copper, does that help? I know there is some funky business with al cu mixes...

you have brass fittings too. but still, oxidation will happen with copper and water alone from what i have seen. redline stops things from growing too. you dont want stuff living in your lines now do ya?

uhh no, you gotta read a thread before replying.
my tests prove this statement wrong.

try Pep Boys, Napa Auto Parts, and Discount Auto Parts. i believe Discount Auto has it in stock in their stores; too bad theres no Discount Auto Parts where i live lol.

will water wetter stop biological growth? some-1 said it didnt. what kind of biocide (i think thats right) should you use to prevent strange mutations from growing in your cooling system?

Just filtered water here.

I am a long time user of water wetter in my race car, up till a few years ago. I am not sure what caused the ww to react the way it did, but I have seen many posts in the past 1.5yrs where ww did the same thing in watercooled computer systems.

Here is what I encouter with ww w/car and also read from other puter water abusers. There is some cemical reaction that caused the ww aditive to become like jelatin cloging the radiator. Almost looked like cottage cheeze, but a funky color. I don't know what causes it, but will never use it again because it overheated my racecar causing me to loose a winning race. Not to mention the cost of repairs. And seeing this happen in watercooled puter systems will keep me from using is in my puter system.

Maybe it was just a bad batch that reached less than 1% of the users of ww, but I'm not going to take my chance.

Can't comment on purple ice. Never used the stuff. But as far as corrosion goes, I think it will occur in most any inviroment. Limiting or decreasing the process of corrosion is one thing, keeping algy or other living organizms out of the system is another. Not inroducing o2 to a cooling system will take care of the algy problem. And as far as corrosion goes, I just keep a watchful eye on my system and do a major overhaul about once sometimes twice a year with quaterly inspections.
