Ian, I've tried running the valve the other way around, but noticed no difference. This was before, when I hade a few vacuum leaks and the car wouldnt boost 10psi until 4000rpm.
The valve doesn't clear the hood when installed that way. I have a dent in my hood to prove it. I'd rather not make another one.

Thanks David. I was going to order that kit. Will it solve the problem of air escaping out the screw on the top?

David Floyd

Looks like the kit comes with the o-ring for the top screw, so it will cure that leak also.

Eivind, this is going to sound ghetto but it's what I use - put a drop of sealant (such as Sika if you have that in Norway) over the tb screw... it's a bit of a pain to dig out later on if you need to adjust the idle, but it works

Elvind,

Could you tell me how you made the plug inside the rubber turbo outlet pipe to pressurize the system? I just started my car and got it out of my garage two days ago since putting it in there last december. I did suspension ugrades and a few months ago jumped on a k27/6 that became available. I replaced all of the vacum hoses also except for two and removed the venturi under there also. The car is hesitating violently under boost like someone tied a rope to the back of the car and all of a sudden is pulling it backwards. I think I have to test for leaks. My idle is not that great cold and when its warm its good at 1100 rpm showing 15 hsg on my boost/vacum gauge.

Who sells that kit contac info.?

Eivind, try few things (one at a time) and report any difference.
- disconnect/block the pressure line going to the WG.
- Install the factory BOV

Something is happening when you hit 12psi.. Need to find out what it is.

I had a new accuboost with a bit of dirt on the ball so it wouldn't seat, cleaned it and got lots more boost,

I went to the Norwegian equivalent to Home Depot and got an endcap for a PVC pipe. 50mm (2"). I drilled a small hole and inserted a valve. I had to use some superglue on the valve to make it airtight. I then used the tirecompressor to pressurize the system. I kept an eye on the boost gauge to see how much I was pressurizing the system. With the tirecompressor I got about 5psi of pressure which was enough to reveal a few smaller leaks.

I did try running without bostcontroller, but that was when I had a small leak. I'll try again now.

I don't have the factory CBV. I'll probably get in on the CBV group buy, but that will take a few days / weeks.
Can I run without the CBV (just for a couple of runs), or will this harm the turbo?

fast951

Yes you can run without the BOV (just for testing, few runs only). Do not slam the TB shut at once, gradually ease of boost (slowly close TB). This eliminates possible surge.

Also, I noticed that your boost pressure is slowly building up. At 2500rpm you should be making 5psi or so.

schnellfahrer

I managed to fit the CBV the same way the stock valve sits and spool up was slightly better, but not by much.

Start looking at the WG. Also, on your turbo, the compressor housing has a hole that can be used to read boost or it must be plugged. Make sure it's plugged if not in use.
