Unusual boosting problem
Hey guy's I know we alway's hear the same "Why's my car not boosting" questions, but this one really has me clueless... It's a built H22 boosted setup that does build boost, but it WILL NOT boost past 10lbs. As soon as it reaches 10psi it just stay's there as if something's not allowing the turbo to build boost past that point.
With help from myself and many others, the owner has tried everything to solve this problem. We've checked the timing, swapped camgears, checked for boost leaks, checked and swapped boost guages, swapped intake manifolds, swapped exhaust manifolds, Swapped 3bar MAP sensor's, swapped wastegates, swapped turbo's, double and triple checked the tuning, swapped blowoff valves, swapped throttlebodies... Everything... We even got daring enough to unplug the wastegate line to see if it would boost past 10psi, and it would not. This one really has me confused fellas, any thoughts as to why the setup or engine might be doing this?

Re: Unusual boosting problem
Well, those are some definate possibilities. I know it's not the factory exhaust... I think it's a Thermal setup but I can't be sure at the moment. It is definately a strange problem, I've never seen a car only build a certain ammount of boost and the poor owner has gone through EVERYTHING to figure it out. The IC could also be questionable. Maybe as stated above by running a straight pipe and eliminating it (for testing) that could be the problem.
Any more thoughts fellas? I do appreciate this, I had started running out of ideas myself.
