Yeah the screamer would def be illegal in WA, but I was planning to have the exhaust shop make up a screamer pipe, and a recirculation pipe, so few V band clamps and a block off plate later, I'd have a screamer/recirc...
Thanks man, that helps heaps The first two aren't really a problem, there's heaps of space under my manifold, only the cooler piping and an engine mount to doge (easy).
Yeah I had the same problem with the 1.0 bar actuator, it was making about 12psi with 3mm of pre-tension, when it should make more like 14-15, boost dropped off to about 10 at redline - so clearly didn't want that. The .5bar one I'm using at the moment, has heaps of pretension and makes 10, which it obviously isn't designed for, hence the poor control, I'd imagine it'd work fine at 7psi though. Both were genuine Garrett actuators. My boost source is taken from the cooler pipe closest to the throttle body, and the disco potato has no provision for a nipple located on the comp. housing, thanks bro.
