We've sure learned a lot in the last few weeks with VGT testing, I'm bolting on the last VGT setup tonight, with dyno runs tomorrow. I'll be glad when those are over. Tonight's switch makes about 8 different VGT setups ranging from 53-59 mm inducers I've tried since bolting on the 72 atmo. Now I will finally be able to pull pull my bald 37's off in favor of the new 38's without affecting data collection.
I was planning on swapping out my 60 hp nozzles in favor of 85's, or 110's, and will eventually, but I've still got enough fuel on the table to see performance differences between the next round of turbos, even though they won't be as dramatic as more fuel would make them. For now though, I suppose I'll continue to enjoy my low EGT's, and lack of smoke.
I gotta admit, I'm pretty anxous to install this one soon.
