I have been working with a local exhaust/diesel shop and they should have my set built in the next few weeks.:cool2: I should have pics soon. We are hoping to find some HP and torque but also drop egt's and have quicker spool-up. They will be coated and also have bungs for EGT sensor.

Yes, pinnacle power is building them. I will be going to a dyno to test them and make sure they work. They have a set for cummins and just got done with the 7.3 powerstroke set.

Keep us posted. I'm anxious to see how they work out. Just curious, but what kind of material are they using?

PVC ;)

Seriously, it'll be interesting to see what gains can be made from adding headers.

Header on a diesel wouldn't add any level of sound what so ever, the header feed into the turbo not to the atmosphere

Maybe not quite true. There seems to be a certain amount of noise that indeed does escape through the thinner walled material. The thicker cast iron does seem to stop most of this.

They will be made of 409 stainless the flanges will be cut from 3/8's plate. They will be coated from HPC flat black to help cool egt's and underhood temps. Might have a polished available to for guys that like the bling bling.

So whats the prognosis tlee05? Any In-Process pics? Are you carrying them all the way to the turbo pedestal, or just replacing the manifold?

In a diesel application is there any advantage or disadvantage to runner length, or does the turbo back pressure negate any of the scavenging effects?:think:

I'm still working on getting the flanges finished up. We should have somthing more end of next week. Their will definetly be some pictures of work in progress photos. We probably will do somthing with the up pipes, Just not sure yet. I've got some ideas, can't tell you or I'd have to kill you. I'm afraid they won't be rally cheap. The ones we're building for the fords are a 4-1 desing all equal length. They're pretty labor intensive. We'll know more in the following weeks

Why use 409, one of the cheapest grades of stainless tubing. At the very minimum you should use 304 or even better 321.

I'm sure you guys have put a lot of time and money into the program and I would hate to see it wasted on inferior material.

Just some helpful tips.

EGT Bung fitting

Will both sides have a bung fitting for egt readings? or just one side?
