Well (this is on the one minute 95% pull), stock went from 1400+ and climbing, to (with up pipes only) 1340 and climbing, to (up pipes and headers) 1320 holding

 

what about the other testers, i hit 1700+ if i lay into it for too long

 

Don't know. This is just on my end, the towing end.

I will assume, it will help but don't know for deffinant. That's for others to tell.

 

i see. I guess its up to chris to tell me more info abouts them

 

Well, not totally. I just don't want to mislead. Major flames come with 'here-say', so I'm CYAing.

I'd suspect you would loose many * while gaining major HP/torque.

 

thats a given, but the talk about headers failing got me thinkin about what makes them fail

the stock ones seem to take a beating very well

Theres alot of factors that could lead to this, like where do the headers fail at, and what kind of metal are they made from, when they are first made were they ever heated and then dunked into water to cool, and how they dissipate heat, Whats the max thickness, the min thickness.

how hot does the headers them selves get, its seems to be made out of less metal than the stock manifolds so they can heat up faster. no heat shields.

maybe the main thing is the longevity of them, the internet got all these horror stories runnin around

 

I *think* failure is from leakage, not the materials melting to ablivion. Yes, it has slip joint, but this has been tested long before I go my set and *so far* no leakage. If it does, I'll be the first to say so. This all an experiment, you have to start here to reach the final goal.

 

yes this is true. But Thomas Edison didn't invent the light bulb on his first try

the material composition of the "super alloy" inconel and the manifolds, do you happen to know the specs?

what about weight. stock vs TxC.

Hardness.

CFM flow, Surface area on the inside, drive pressure. Manifold heat stock vs TxC after 1600* EGT's.

have yall been measuring and taking note of these factors?

a good knowledge in metallurgy would help

hmm this inconel is some strong stuff....

 

This is not the 'first try' and it didn't happen overnight, plus there are many people involved. People that are much more knowledgeble about this than me. All I can tell you is what's happening on my end of it and on my end (the towing side) the result are looking very promising, but I won't know for sure till this weekends pull.

This pull will be matched with a previous pull I made when 'stock'. Same route, same load, and the cruise control on to take out the 'driver factor'. Only thing possibly different will be outside temps (now it's hotter) and wind conditions, which is out of my control. Many systems will be logged, most important being EGT's.
