Hi guys, well after 6 months of buying parts from here, doing up the Soarer and getting a ton of help from you guys the car is up and running. Now the problem is it seems to be stuck at 10psi according to the boost controller (profec b spec II), though the emanage ultimate is reading around 18psi. Now the car goes good, but not what I would expect so I'm inclined to think it would be about 10psi. I've given it all its got and the reading on the boost won't go over 101, which I think means 10psi (I have changed it to psi from kpa).

Now one thing I think I could of done wrong was the air tubing from the waste-gate and boost solenoid. Top of the waste-gate (nipple which can swing) goes to COM, nipple off middle of the waste-gate goes to a Y connector, which also then gets the tubing from the NC port on the solenoid, and then I feed this to the very back right nipple coming off of the manifold (looking at the engine). Now, I'm not sure if I should be connecting the waste gate and the piping from the NC port together, or if these should be going to separate places. The tubing to the boost controller comes from the second back right nipple (This was on the same line as the stock sensor but I changed it and it made no difference).

Now I'm going to try the trick with the aerosol lid to check the inter-cooler piping this weekend, and if I get the guts i'll try the trick where you disconnect the piping from the waste-gate to see if that's the problem. It could also be the cat that I have read.

The e manage was from Harley who I think was having problems too but I'm sure it's not that. The turbo was from Tony and it seems fine (TD06-25G). It could be the boost controller because it was the only thing I didn't get from soarercentral :-) but it does seem to be working at least till 10 psi. I get a reading of -85 when I start the car but what I've read this is normal, but maybe not.

Any help on this issue would be great, because after putting all this work into it (I'll do a right up one day) just pulling a bit harder then stock isn't really a satisfying feeling. I also have a Monza SSQV BOV welded on the cooler piping after the inter-cooler which I read I could tighten at the back as well. This was on the cooler when I got it.

Oh also I got the boost controller settings from a forum post off here for 17.5 psi. I've tried a few others but it does seem to like sticking to 100/101 on the controller still.

*cross fingers* some one can help.

Have you got a boost gauge? If not you need to get one before you start increasing boost pressure. I believe the Profec measures in percent not psi, might be wrong but I think that's how mine works.

Hi Jeff, yeah it is in percentage when setting the controller but when you get a peak reading, the 100 or 101 values ive mentioned, ive been told this has been times by 10 from its psi value. That i understand anyway. But yeah i should be getting a gauge, im just worried that like the emu saying 18 psi it will too, and its some how the controller restricting the wastegate to get higher then 10psi.

The adjustments are made in % , but if its set to PSI and not BAR then the boost guage section of it is relevant to pSI .

100 = 10psi . 108 = 10.8psi . mine peaks @ 182 which is 18.2psi . As i have mine set to psi .

Thought thats how it went but big ups for the confirmation. Sometimes u know but dont :-) internet i guess but saves a bit. Any advice on the y connector at all on the profec b spec II? Should of changed that subject cause it prob that or something i can test at least.

Not sure what you mean by Y connector ? Mine only has 1 line going in .

Do you have a 1 way filter in the Vac line going into the profec B ?

Or do you mean the Solenoid ?

So one from the solenoid nc port and one from the middle of the wastegate into a y connector (like a t piece) and then from the y connector to the manifold.

So I connected the cat up, did the inter-cooler testing with the air compressor and that was fine. It was the boost controller. I disconnected it and it ran over 10psi. Also the Y piece I was talking about is fine to do.

Typical, the only thing I didn't buy from Soarercentral doesn't work. Thanks for your help.
