BD Quick Spool Valve Install with Pics

Wow, I just got the link to this from another thread. Looks like I missed a lot of drama.:eek:
 
With the quick spool valve, yes, the larger housing acts better. I could easily push over 20+psi with the small housing. Now I am getting 17psi at full tilt with the large housing. Some of you might be anxious to know, I did try to increase fueling yesterday but ran into some snags and had to abandon it for another day. It's in the works sometime though
 
Boost Pressure. There should be pictures at the start of the thread that show the turbo and valve. The blue line running from the turbo to the valve has boosted air in it. The pressure acts on a spring inside the can and pushes it downward, actuating the arm to open the valve. When no boost is present, the valve snaps shut again from the spring tension. The more boost, the further it pushes until the valve is completely open. It is set to open around 14psi. I know it really is only opening right now for about 3psi worth of full open turbine housing, but I am simply out of fuel right now. I am hoping with a lift pump upgrade and another 1/8-1/4 turn on the pump, I can run around 20psi out of it. That is what I am aiming for right now.
 
Great work 6.5. The ideas you folks come up with on this forum blow my mind every day. It keeps me coming back, day after day. Keep it up, I will follow this thread, as I am looking to do something different with my turbo in the near future. I have the GM3 Butt plugg as some refer to it. LOL
 
I actually just got the FRB-5 lift pump in the mail today. I will be installing them this weekend hopefully if anybody is curious.
 
Just finally got around to reading this whole thread!
Thanks again for your business.
Very nice work/idea you had. Im real interested in seeing if someone comes up with a vac operated version.
Do you think the QSV could be rotated 180 degrees so the gold spring thing points forward? On my truck I can easily relocate the rad tank but most others won't be able to as easy.
 
Thank you for an awesome product line. And I am fairly positive it would hit the valve cover. Plus, it takes up a whole lot more room than it looks like. Going forward, you run into having to possibly re-do some hard lines on the coolant system, maybe having to re-work the air plenum, probably some other stuff. Mounted like I had it was probably the easiest way. The AC could maybe have stayed but it didnt work anyways on mine. I am pretty sure with some skillful line bending, it could be kept, and the overflow tank was fairly straight forward a swap. Where I mounted it is the best place possible in my opinion, where there is room, and it actually still leaves room to open the fuel filter manager just fine.

I tell ya what would even be easier than that, is about 75-100 of us all emailing BD, and asking for a set made for a 6.5L diesel. Sure would make things easy :hihi: I do swear that it is the people who try to get power out of these old beasts that leads to some quality time learning how to fabricate
 
Can you post some more pictures?

I would be very interested in one made to clear everything on a 1995. BD can borrow mine to make it if they like. The cooling system requiring the pressurized tank there leaves me going back to a 1993 radiator setup style aka: eliminating the pressurized surge tank with a overflow bottle.

AC lines can be made and move the accumulator if necessary.

Other people are simply not moving on this project very fast. I need one in the summer heat down here badly. I have been debating all evening to take advantage of the sale going on.
 
Unless I have parts in my hand I have a hard time getting the movements, theory...ect and I lack knowlege of the vac system/actuator SO, this may be a dumb thought, but could you take the vac actuator off a GMXX turbo and fab it up on the QSV replacing the BD spring?

EDIT: Another thought, Can the QSV be turned 180* AND! upside down so actuator is near inner fender? Would that mess with the flow controlling the QSV

I'll be checking tomorrow on pricing. How long is the sale?
 
I am not sure since I am not familiar with the vac systems. I will try to post some pictures tomorrow or the next day in here if I remember and I will try to get a bunch of different angles so it can give you an idea of size and fit. If that would help.
 
Sale is at XDP till 6/17/13 thanks to hookedup50 for pointing that out.

Measuring tape from firewall to valve where surge tank/overflow would hit and accumulator in the pictures would really help.
