High power inconel headers.
 

Has any one made one yet?

I'm looking for a nice write up.

Do to the costs involved I dought it. The material by it self would be more expensive then any production header on the market. Could someone use inconel materials into there already existing jigs, yes. If you truly want a header made out of it I would recommend calling all the header manufactures and get a quote, expect no less the triple or quadruple the price, most likely more. If not interested in spending that then just let idea pass. It is a great material but very expensive. Look at the differences on basic google search for the cost of just j bends and 3/8" thick and 1/2" thick materials for making flanges. Not trying to talk down to you at all in this as a lot do not relies the material cost involved. I hope this has helped in some way and not come off as preachy. Also there is always an option of getting one fabbed for your self locally.

U will never see a inconel set up for the public

Would it even be worth it for a NA engine? I could see it being used in a FI race build, or something requiring the extreme heat resistance...

Why on earth would you even want this? Your exhaust gas temps will never reach the point of making good use of incolnel. Besides that its heavy and $$$$$$.

I eagerly await your threads regarding how an sr20 can fetch a premium a week before race wars.

If you want to drop a ridiculous amount of money on headers just have a set made out of Titanium.

As said, very expensive, and difficult to work with. I've machined Inconel 600, a lower strength alloy, and even that just sucks work work with. The primary benefit it strength and corrosion resistance at high temperature. Weight was mentioned, yes the nickle base is heavier than iron, but not by much. Iron is 491 lbs per cubic foot and nickle is 555 lbs per cubic foot, 13% difference but inconel can be made thinner.

But yeah, really expensive. I wouldn't use titanium for a header, much weaker at high temperature, a lot easier to machine though.

Tell you what when your car gets as hot as a combustion turbine you let me know.

Another Downside to titanium from a fabricators view is its a bit less forgiving to weld, compared to stainless, steel or even inconel.

Inconel is easier to machine at slower rate of speed with a highspeed super fine grain tool steel, ive found most carbide to cut like crap no matter what speed you machine. we do alot of inconel at our machine shop becuase lots of factories use inconel pieces in their machines making molten plastic and such.
We end up having to reweld surfaces and machine everything back to tolerance.


But anyways, its simply not beneficial in anyway to use on anything aside from a crazy race built engine like that of a f1 car.


Diesel pulling trucks run ridiculous egt's but they still use stainless headers. :iono:

I think susper sprint mentioned they could make some if people were serious about it.

EDIT: LINK

I have been anxiously awaiting the release of some attainable titanium headers and a titanium over pipe. This could explain the long wait. Are titanium headers known to break?

I thought titanium had a pretty high melting point. I'm not a welder or anything though, don't know where I got that from.

This thread doesn't make sense. The material is nothing to do with 'high power', it's to do with weight and suitability for use (e.g. longevity).

Inconel doesn't really give you anything above stainless, for power.

If you want 'high power', then speak to a proper engineer who can design you a manifold fit for purpose, not just some off the shelf rubbish.

Nonsense!
