Secondary 6.7 powerstroke wastegate
I was looking through some literature on the 6.7 today, and it talked about the EGR valve being used as a secondary wastegate in high boost situation's.
Then I started wondering out of all the trucks I have seen or heard of turbo replacements on how many were deleted (all of them) and how many had tightened or adjusted the wastegate (a few i know of).
It also seems like without the backpressure of the dpf that would fuel the fire as far as overspeed.
My point is would a wastegate kit plumbed into the passenger side manifold and piped back to the downpipe be enough to relieve the pressure and get a few extra rwhp out of the stock charger.
I know the restrictive exhaust is the problem, but is a complete turbo kit/replacement required?
We have decided that there is not much fuel available for added power over and above.
With the egr cooler out of the way we have plenty of room.
I think a wastegate kit could be made for around 500 dollars.
