ok guys im wanting to build twins for my truck and want to leave my pacbrake on would it "KILL" my pacbrake buy putting a CAT (80-somthing-20)turbo under it its off a D10? to me the concept will still be there for the breaking by making more backpressure on the upper turbo (current hx35/40 hybrig w non-gated 16cm housing) whats everyones opinion on this

 

Which Pacbrake is it? 3" elbow mount? or inline?

 

its the 3 inch elbow mount, what i was thinkin is making a custom pipe to bolt directly onto the pacbrake then to the CAT turbo flange

 

Thats interesting.. I don't know how well the primary turbo would like it when it closes. That would be some fun trying to weld or make a connection from the donut flange to the primary.

 

I've seen a lot of guys run them off the bottom charger. What exact turbo are you running? you'll want to get some specs and a map for it.

dont know what the exact size is but it will need a 5" downpipe wich the break will not fit on it

 

I've seen guys running 5" brakes is what I was getting at, but to keep your existing brake, you might be hard pressed to fit it all in there.
