Re: exhaust leak; Tips on finding them?
turned up nothin, although I have a hard time believe it worked. the only place i could really see it leaking would be in between the turbo and the manifold. I have to be loosing alot of air somewhere to only be getting max boost of 15 psi...I have to think about it logically.
the turbo is a constant, it did not do this with the previous turbo, but I rebuilt the whole motor in the process of changing turbos, so that means little.
same boost solenoid.
I have switched out for a much much stiffer actuator, with no results.
I have fixed many leaks on the intake side, and now seem to only have one in my throttle shaft, which is apparently minuscule. also, this has done nothing besides increase throttle response.
gate is programmed to be closed, but I have not proven that it remains so.
I cannot find or hear any exhaust leaks.
the turbo fins are all straight, it spins freely, although it does have a tiny amount of in and out play (14cm 20G)
I am not sure what to do next, other than to replace the boost solenoid with an external regulator, just to see if it changes. I have a hard time believing that it will, because it is doing the same thing with both actuators, the stock 20g one, and one with a base pressure of 18psi. The issue is it will only build around 14-15 psi, it will spike slightly when it shifts into third, to about 19, but will quickly come back down to 15. i do hear a slight hissing.
