I want to see some videos of this thing in action!
I want to do a project like this sooo bad! Great work!
A general project update (and I appolgize on falling behind on some pics and write-ups..hope to find some time for that shortly):
I am getting closer to getting the engine tuned properly now.
Boost has been spiking around 32psi with N75 sitting at 94%. This was most likely due to the vanes not opening enough.
At VWMikels suggestion, I removed the turbo and played with the clocking of the housing a bit more to try and get control of the WOT boost levels.
I first compared vane location and range to my other GT2056 turbos. It was identical, so for some reason, this particular VNT20 model does not open the vanes vary much before the arm hits the internal stop. I decided to pull the housing dowel pin and see how much further I could rotate the bearing cartriage on the exhaust housing. I got about another 2mm (measured at the turbine flange) of movement, which does not sound like much, but seemed to add around 5-10deg on the vane angle. I then re-adjusted the closed vane stop screw until the lever did not reach it anymore. After determining that location, I turned it back in a touch for some contact. With this adjustment and the custom clocking, the little vane arms are able to travel from guide wheel to guide wheel (guide wheels on internal adjuster ring). Vanes will not close as much as I would like, but they are not too bad.
I then reinstalled the turbo and tested with data logging. Boost is now maintained at 26psi WOT and 75% duty cycle on N75.
So the tiny re-clocking movement corrected the problem and I am now ready to get a tune update to address spooling issues and full power limits.
Some youtube vids will follow..probably will show drive by under full boost, WOT Acceleration from rolling start, and dash view acceleration 2nd thru 4th gear. Any other specific request for vids? 1/4mile time etc may have to wait till next spring.
Tonight I will be trying to find a 2.4amp current draw that keeps killing my battery. Looks like I will need to do some more wire chop chop again..arg. I think I have installed and removed everything on my converstion 3-4 times now.
