Re: Boost Dropping
Color of the wg spring is red, but I don't know if it's tial's little or big spring. So it's either 5.80psi or 11.60psi. Elevation is right around 400ft (seen anywhere from 390-420ft). The BOV is running off a vacume T connected to the back of the IM and the boost gauge. The wg is run from the port on the compressor side of the turbo (I'm not up on my turbo terminology, but it's a vacume port on the inlet side of the turbo). The mbc is between the port on the inlet side of the turbo, and goes to the port on the back of the wg. As far as I can tell; all vacume lines, fuel lines, MAP, missing link; are all mounted correctly. The wg doesn't seem to have an O ring at all, just 2 gaskets that came with it. Infact the gaskets were the only hardware that came with the wg, not even the port that screws into the top of the wg (that would hit the hood anyways).
Last night we messed with it for hours and rechecked everything again. But this time the BOV didn't make a sound at all. It's back to 7psi again and it didn't make even the slightest chirp. And I found out that the BOV is used, so no one knows how well it's been working. But it was midnight by the time we started narrowing it down to that, so we'll have to check that today. We did get it to go to 10 psi again yesterday (earlier in the evening), but then it suddenly stopped again without touching anything. But the boost gauge was fluttering like crazy when it hit that high.
I knew about the 3-bar map sensor, but the customer just didn't want to buy it yet. But he also thinks that he can get 600+ whp with his Apexi WS2 exhaust. And he's been driving the car, since the break in period, with 7psi and only using an FMU for engine managment. I'm wondering if maybe bad rings (caused by the rich environment) could cause the problems we're having. I would assume that it would cause a loss in power (and obviously compression), but I don't know if it would effect the turbo at all. I hate this car...
Edit - we replaced the Tial wg with a delta gate one and it hit 14psi. But the BOV still wouldn't go off, so we replaced it with another ssqv. Everything seems to be working fine now, other than it running rich at 14psi. Idk...
