I'm not going to keep that on there very long. Going intercooled.

Any problems with your drive pressure line getting plugged with soot? looks like a pretty easy setup that you have how is it working so far?

Not yet. It's worked great. I'll be putting a bigger filter on it though.

I still have the stock filter on it so all it really does is make the turbo louder. Need to get a better filter on it. Still have the old turbo in this picture.

Drive pressure regulated with a neddle valve pushes the turbo open. Boost pressure pushes against it to keep it equlized. And a spring closes it when you let off.

parts-
copper tubbing
neddle valve
rubber fuel line
filter for an air compresor
4 hose barb fittings and clamps
2 fitting for the copper
air cylender off of Ebay
90* boot and clamps
home made crossover and exaust adapter
exaust flange off of a 6.0 powerstroke
1' of flex pipe and two band clamps
HE351VGT turbo

Added up it comes to about $320 for the whole setup

Drive pressure is comes from the exhaust manifold. (driveing the turbo) Go for it they're great turbos.
