On a happy note the Trooper is back and running tip top. The turbocharger works like a charm. Apparently several exhaust leaks at the manifold had adversely affected its ability to boost completely. Makes sense now that I think about it. <img src="/forums/images/graemlins/baby.gif" alt="" />
It takes all the exhaust pressure to spin the fan in the turbocharger, yet much of the exhaust was escaping through the leaks, taking the path of least resistance, leaving no energy for boost power. I did find one issue which was present on both engines: A missing manifold stud in the (lower) middle of the exhaust manifold. I couldn't find a suitable replacement in my stash, so I left it out <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> this is probably going to come back and bite me at some point.
For now I am very happy to have some power back. The Trooper made it up (our) Nine Mile Hill at 50 miles an hour hauling all the tools and supplies I need to do wireless Internet installations plus 30 gallons of choice waste veggie oil scored from the local Chinese restaurant <img src="/forums/images/graemlins/cheers.gif" alt="" />
So heck yeah, I'm stoked.
