Out there again yesterday and I've (with the help of feral4mr2 and GUN METAL 87 SC) determined that it's boost cut causing the issues. This was verified by a '34' fault code and the fact that it was hitting 15PSI on the boost gauge.
So what would cause my car to get to 15PSI? I would think the only reason to be the actuator not opening up the wastegate.
So why would the actuator not be working?
1) It's not connected up right
Even though my compressor housing is clocked 180 degrees, it's still connected up to the same pipe.
2) The dump pipe is stopping the wastegate from opening
Shouldn't be, I checked clearance before fitting the aftermarket 3" pipe. And it hits 15PSI super quick, if at least some air was escaping, time from 0-15PSI should be more than the fraction of a second that it is.
3) The actuator is stopping the wastgeate from opening far enough
Could be, but I woudn't think so. When I made the new bracket up for the actuator, I positioned the actuator by pulling it away far enough that the wastegate was firmly held shut, but not far enough away that the actuator rod was pulling out of the actuator. And as above if this was the problem, it should boost quick to 7PSI then creep the rest.
4) There is some sort of leak in the line between the compressor and the actuator.
Possibly, although not likely, it's a brand new hose. I might before I replace the actuator though, plumb a boost gauge in to it and see what pressure the actuator is being fed.
5) The actuator is stuffed
This is what I've got my money on. Even though I was VERY careful when welding the actuator bracket to the actuator not to get it too hot, maybe I stuffed it. Or maybe it was stuffed when I bought it.
Is there anything I have missed, neglected?
If I went with one of these what would I plumb the turbo VSV to? What's that thing for anyways?
Cheers,
dave
