  1. Distilled water involves some form of evaporation process from the feed water with subsequent consensation of that water vapor. The typical process is to heat the water to make steam (sometimes with a negative pressure assist) and then cool the vapor stream at some remote place to make distilled water. Deionised water is water which has been passed through a bed of resin beads which have selective anodic and cathodic sites chemically bonded to them--in effect, the ions from the dissolved and disassociated minerals are attracted to the ionic sites on the beads. The treated water will have less ionic load after the minerals are removed from the feed stream. Distilled water, depending on the feedstock and the process involved, usually has a fair amount of dissolved gasses and also contains some of the volatile components from the feed water (such as volatile organic components). To make ultrapure water, distilled water is often degassed and then treated with deionizing resins. The rationale behind this is the deionizing resins are fairly expensive and do not have a large capacity to extract ions, so using distilled water as a feedstock greatly prolongs the life of the resin beds. After distillation, deionization and degassing, the water can be considered ultrapure. In some applications, and if the feed water is very clean, that is, has a very low ionic component load, then reverse osmosis can sometimes be used to remove some of the minerals before deionization instead of distillation. Reverse osmosis is fundamentally a hyper filtration process whereby molecules are filtered out to some extent. [i know, this is an oversimplification, but this is a mixed audience.] There is a fair amount of operation involved in reverse osmosis and depending on the quality of the feed water, chemical flocculation or preconditioning of the water is mandated. I should point out that regardless of treatment, softening of the water is usually a first step to prevent scaling of the treatment system. Ultrapure water has a very low conductivity and is a very aggressive solvent which will attack stainless steels and even glass. Really pure water is actually difficult to work with and store--it readily absorbs gasses and requires Teflon coated containers under inert gases. For critical cooling applications you are basically looking to prevent scale formation on heated or cooled surfaces. The typical scale components of "hard" water are magnesium and calcium carbonates; these compounds have a narrow band of solubilities in water as dependent on temperature--if the temperature is heated above 90C or cooled below 2C the carbonates tend to precipitate out of the water and deposit on your expensive equipment as a scale deposit. Scale reduces the coolant flow and disrupts the transfer of heat in the system, both undesirable and potentially damaging conditions. Distilled water is probably sufficient for your application and is much less expensive than deionised water. Also, the dissolved gasses and small amount of ionic load inherent in distilled water will help to protect your metal contact surfaces from corrosion by the water. If, for some reason, the distilled water is eating your equipment (watch the welds!), you may have to go to another coolant fluid, perhaps a chlorinated or fluorinated hydrocarbon. Tin plating the water contact surfaces is also a very effective means of protecting components from corrosion by water, and tin and tin oxides are very insoluble in water. However, since your equipment was designed to be water cooled, I suspect distilled water will meet your needs
  2. So are you paying or not? If its a No then just say and we both know where we stand.
  3. As for having your details - HOw else Am I meant to sort all this mess out if I go and destroy all the details, on a side note yours in the only details I have actually as I took them over the phone in the car on my PDA - a one off. I usually use Protx which allows recharging but I never get to re-see the card number.
  4. Its dated that day because I had an error on the Excel spreadsheet and it always inserted todays day when opening. I never fixed the bug. I willg et you another invoice - all you had to do was ask. As for your parts then I am sorry you got caught up in teh end of MkivStore - But I have paid for the parts you have now out of my own pocket, adn you had some upgrades in there. Flywheel bolts do NOT come with Exedy clutches. But I have a set if you want them.
  5. Sold to GZ Aero Jon. Pending bank transfer in 3 days else back up for sale - 2nd dibbs welcome.
  6. 1 of tehedecat pipes I hade made up and commissioned in 2 1/5 stainless. Cut and welded with a perfectly measured dogleg bend. This is simply the best fit for the Supra. Brand new - was selling them for £199 I have 1 left over. £100 +delivery. Bank trasnfer only. Ask anyone who has one of mine - they are a perfect fit.
  7. I might even turn up if I still have the Single by then.
  8. Check your security settings.
  9. I have my Single Turbo Supra for sale and Im in Weston. Welcome back BTW
  10. Im aware of mechanical grp limits, but that seems like an awefullot of understeer from a car like that.
  11. The worste case of eating E102 Ive ever seen. Although I do feel its a bit fake.
  12. Do you have beef with me? Have I ever owed you anything? ever? If you answer no then why not just keep your uninformed comments to yourself. Your NOT HELPING!
  13. Yeah I know - frustration sets in.
  14. Easy change Chris. Very easy. Whole unit is best.
  15. Correct when I was desparate for cash. Gaz as you know sometimes you need to generate money, and sometimes you can sell at a higher price.
  16. NO actually 2 weeks is too long to wait for £850 when I have nothing. But carry on you too - keep putting the boot in - it must be fun for you. {edited} Didnt seem to complain when I sent you free stuff Gamer.
  17. Turbo seals. do you have a 1st decat?
  18. Neither, both budget. Go for a Greddy Ti or and HKS Ti.
  19. Yes I have a brand new one for £30
