Sure it does.
The twin scroll exhaust housing has 2 sides.
So if I close one side off.
That changes the AR. you have cut that ar in half.

Ah i see, pretty much doubling the volume into 1 volute to get it spooling quicker then opening up to both

Too bad you can't change which side your closing off (and see which half makes it spool better).

Still lookong for a donor truck. It needs 3.73 front end, good front frame, and NP149 transfer case. A center console would be a plus.

I had wondered this too. If it wasnt welded on I would flip it around to see what happens. As it is now, the port furthest away from the center section is always getting the exhaust.

Yes very much so. Very glad I did it. I might still do the air solenoid like you suggested. I already have a Hobbs running my 2nd fuel pump.

Hmm...now you have me wanting to do this when I build my turbo setup. All in all, what would you say it cost you to add that to the manifold? And other than welding it on like any other turbo flange and hooking it up to a vacuum source, what else did it take to make it work?
