has anyone ever ported the intake port on boost side of the turbo, i have seen on turbo websites that were selling replacement turbos that hav had this done, they also claim 30 extra hp by doing this. Anyone hear of this?

I have seen pic of a the compressor housing ported out on a older powerstroke. I dunno what kind of gains can be expected though. ATS sells a ported housing for the newer 7.3's. and they "claim" about 30 hp. I doubt youll see that kind of gain on a older powerstroke.

I guess it could not hurt, I have a buddy that works at a machine shop and said we could do it for free, if nothing else it will let more air in easier, right?

yep it'll help it breathe easier which will give you more power if you have unburnt fuel.

If I remember right bulrid8 ported his. I don't remember what difference it made but maybe he will chime in.

Yes, I ported mine. I did alot of talking with swamp and we talked about stuff to try. If you look in the inlet opening, there is a groove cut in about 1/8". I filled this in with JB weld and covered with an epoxy. Then worked on smoothing the whole opening and widening it as much as I could. This was to help the air flow as smooth as could be. Then I bead blasted the entire inside of the compressor housing, to give it a glass finish.

I forgot to dyno it after it was done, so I don't know HP gains. But, I did gain 5 psi in boost and the turbo sounded much smoother. Did not cost me anything and I think it did help alot. I was at 400rwhp on a stock turbo and never killed it, so it had to help a little!

Hey bulrid8 I was checking out your pic and saw your map sim what do you gain by having this and how does it work? I'm guessing you use it to simulate boost to fuel more off idle without actual boost or am I way off?

It did a good job, But I took it out. It was to hard to keep it dialed in, to different conditions. If you took the time to set it up right, it really picked up the low end power!

So I don't suppose you would like to share some of the wiring info? I was going to take a reostat and T into the supply and the signal from the map sensor to be able to fool the computer and have it adjustable in the cab. I noticed you had three knobs what did each one do
