update-swapping

I bet that will be a good combo. The larger housing should let you take better advantage of the quick spool valve. Looking foward to hearing your results. Some dyno results sure would be nice too.
 
Good results. No mileage tests yet but I got what i wanted with the larger housing. Boost is down at 70mph (2500rpm). Hopefully mileage will rise. Not like it wasn't good before but I am driving 6 hours tomorrow and was curious how it would do. Not to fret though. Boost is always on tap. I can still peg the big housing out to 17psi. Starts to boost just only slightly later and I can't tell that is boosts any slower. If it does, barely noticeable. I see good things in the future.
 
No dyno. No money. Very little time. Plus it is unfair to compare dyno results until I am not running winter blend diesel anymore. My opinion
 
I'd like to see what the quick spool valve could do if you had it set up on an electric actuator of some sort that would allow you to open it at cruise to get the least amount of boost and backpressure, but close it during spoolup times to get the best spool up. Set it to open up around 5 pounds of boost and see what it could do. I still say there is alot of potential here with the quick spool valve and some creative setup.
 
Can you swap springs in the quick spool valve to change the pressure when is opens?

Sure would be sweet to have full control of the quick spool valve especially for an exhaust brake feature
 
With the valve now a run only about 2psi at 80mph.its perfect.it keeps egt's in check and boost is always on tap when needed. Yet not enough boost to hinder mileage. This setup is perfect although I may change springs to open at 10psi
 
On summer blend I made a 6 hour trip, averaging 75-80mph (2700-2900rpm) for basically the entire trip, with the normal housing and quick spool valve, I came out to 14.47mpg, which considering the rpm, is pretty good in my book. On winter blend, the exact same trip, same speed, with the larger housing and quick spool valve, came out to 15.89mpg. So not bad.
 
Not bad at all for winter fuel. I'm curious what my 95 would be doing now on summer fuel and less idling (warm up and coffee stops), im sure it would do better with att but don't plan to find out.
