With a decent rad set-up, it'll take ages to get hot. It's not a backwards step for a street car at all.

End of the day water cools better than air anyway. So on a 30 degree day, even if the water temp is 40 degrees it'll do a better job.

You show some data and i'll take my words back, but water will always cool MASSIVELY better than air. Get a decent size rad, decent sized core

Quite a few manu's from the factory use W2A, I'd take a guess mainly @ space saving vs performance given it would cost more, but hey, the Veyron uses it - can't be to shit! :)

The only disadvantages are weight, more complex installation and the cost. It wouldn't be simple and you would need to use decent parts & fittings for reliability where a A2A doesn't matter.

You'd also need to workout what motor & how much flow, vs the cooling etc.

Water cools better and has more heat capacity, need more heat capacity? add more water, or add more cooling.

If appropriately chosen gear is used it can work fantastically in any scenario, the main issue is the appropriate gear for the engine/turbo combination can often weigh so much it is not worth while, eg a track car.

For a street car if you don't mind adding 100kg of water I can imagine it cooling any system you can dream up, even with a undersized radiator it would take a long time to get heat soaked.

W2A is a good option for a whole lot of reasons but you still need a decent radiator, thermo fan, good quality water pump and a good core.

I have installed a W2A system on a turbo diesel patrol and it is miles ahead of the pissy little A2A system in almost every way except complexity. And it is not that cheap by the time you buy decent silicon joiners for the air side and a good pump and radiator for the wet side (recommend a Bosch Cobra pump)and custom fab everything. Whatever you do don't let any of the eBay style merchants convince you that a little oil cooler sized radiator will work efficiently (unless you have a huge storage thank somewhere for additional water to act as a bigger soak).

Looked into a similar setup on a GTR and it just didn't stack up over A2A.

For about 1/10th of the weight of a water intercooler you could have a NOS intercooler spray and a 100 shot of NOS bottle.

The reason they are good for drag is peeps put ice and dry ice in the water intercooler, not really practical on street or track.

      Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy.

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.

      Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
