Laughing at all of the back and forth over design of turbo (what this thread originated as) headers...morphing into header design for normally aspirated engines. Classic Nasioc blueprint.

I have a Perrin 4-2-1 header ATM and a killer b pickup tube. I'd really like to make my own header. But only have a mig welder.

I have no clue how successful you actually are, maybe you just scrape by year after year, or maybe you make a killing. Hell, people make a killing selling scam warranties too and there's thread after thread touting them.

funny how you never really follow up on these technical points once I point out the fundamentals

Castings are better than fabbed headers. . . .abandoned, what happened to that one????

stepped headers are for flow, even though it's about pulse timing. . . .no response now on that either, surprising. You should get a fluid dynamics textbook and see how rational it is to bump up a properly sized tube for flow purposes. It's literally the opposite of what you said to fanboy #2, but he went along with it so you must be right.

What did you seriously think I thought stepped meant? nothing again. . . . abandoned. I mean really what on earth did you think?

I never said everything you say is 'horrible', there are times you absolutely know what you are talking about, but this is a topic you just don't understand and I'm sorry anybody who doesn't recognize you are biased as hell to push your own products is just naive.
I don't make money selling things to people on this site, I have no incentive to push biased information, that would be you.

anyhow, please correct me on any of your points about castings being a better header design, or castings being cheaper and faster, or slower and more expensive because you abandoned each and every point you made after directly contradicting yourself.

He dug way into pushing his products and proved a complete lack of understanding one post after the next, and he had three fan boys on here propping it up, THREE, Frankly THAT is what Nasioc is known for, blatant misinformation being perpetuated by two or three dudes who just stick to their guns.

This guy really needs a therapist... and to learn how to summorize his words.. and maybe let goo lol...

From what I've learned is there are many people and many ways people are teaching things..

Just because your text book says one thing doesn't mean it's correct.. make logical sense of it..

You can always measure back pressure at multiple locations of a step primary manifold.

I bet you will find no drop in pressure or raise in back pressure..

You know, it's funny, I've never seen a fabricated turbine housing. Someone should tell Garrett/BW/etc that they're leaving power on the table...

Lol now that's true...

I don't even think a CNC machine can make one not enough axis.

Someone should send them better metals to pour into a cast template so they don't rust! LoL

so equal length headers are less prone to cracking as well? Not sure I understand why...both header designs, EL and UEL are going to glow red hot at times and go through the same type of heat cycles.

Because they're more equal in temperature and it's temperature differentials are what cause headers to crack due to different amounts of thermal expansion.

The simple way to think of it is have two bars of metal next to each other that are the same length. Heat them up and they expand/contract together and at the same rate. Now have one shorter then the other, and the longer one expands further. This difference is one of the reasons there are additional stresses with UEL.

OK that makes sense

I had Perrin on my car since 2008 no cracks welded the slip fit. Ported them also.

And they never get glowing red. The tune!

Jr tuned.
