Okay,

Just to let you all know, I'm not going ahead with the group buy.

I'm not really all that happy with the boost control.

It surges a bit, like when it comes on boost it will open the first valve and then the wastegate will open and then boost will drop off a touch and then come back on again.

Also, it will jolt the car as the wastegate opens, which is strange to me....

Boost rises and then as the wastegate opens, and the exhaust note changes, the car jolts forward quite hard. It's very weird, I don't like it.

I think I'm going to get a PowerFC boost up kit for when I install the Power FC and be done with it.

You set it up wrong, that's why it does that.

You need to close the first valve off a bit...

if you have a wastegate actuator rated at 5psi, your relief valve set to 11 psi, and your regulator set to 10psi, then it will behave badly as you have noticed.

I had the same problem when i first played around with mine, but then I figured out how to re-adjust them, and it works perfectly for me...

hahaha, I knew someone would say that....

1. I REALLY CBF starting a group buy - sorry guys

2. I would feel bad charging people, thus I would not bother installing for people

3. I don't have the time....

I could tell you where to get everything though, to set it up yourself...

look for IMI Norgren Pty Ltd in the white pages. Call and order the following:

  • 1 x R07-200-RNKG Inline 07 ¼ Regulator Relieving 7Bar
  • 1 x V07-200-NNKG Inline 07 ¼ Relief Valve 7 Bar
  • 2 x 2069-02 07 Spring 0.7 Bar (brown)

Maybe ask if they have a spring rated to 1 bar instead of a 0.7 bar spring

then go to enzed (heaps around) and get:

brass York 23151-06 3/8-inch check valve, (or equivalent, as long as the cracking pressure is less than say 2psi)

and hoses + barbed fittings + clamps to suit. Speak to the guys at Enzed about the hoses, fittings and clamps, they should sort you out.

The valves come with their own brackets, and I mounted mine next to the air box in the engine bay.

      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?
