i just got quoted $250 per bend for 2 or 2 1/2"...is that ridiculous, or is it about ballpark? i've never priced out inconel before.

 

whats it for

 

i was playing with the idea of making an exhaust manifold and some exhaust parts.

 

whats the benifits from using inconel? if u dont mind me asking

 

Weight and strength.

 

That sounds about right.
Why do you think there aren't to many inconel mani's out there.

 

^ lol

 

INCONEL headers for a F1 car cost is 100,000, there are areas of perfomance that as ordinary people we can never get into, I call it the US and them FACTOR. let us say titanium rotors, forged molibednum 5053 steel no flex E-SHAFTS chrome, a much better cooling system or use of the heat made in the chamber, so much is wasted, come up with a better way of using it.

 

That's about right, I had my 3rotor exhaust manifold made of it.

 

ive considered making some type of intake using round tubular steel without all those damn blockoff plates and with better airflow. what would be the best steel for that?

 

use 321 stainless for your header much less expensive

 

well, i don't mind paying $1k for a manifold if it does what i want and lasts forever, but i think i'll be practicing with some mild steel before i go spending that much just for the pipes

for the intake manifold, use whatever is cheap, then ceramic coat it. intake just holds boost and vacuum, along with its own weight. it doesn't see the punishment that the exhaust does.

 

Inconel is pretty tough to cut and grind on and even harder to weld good. Mild steel is a cakewalk compared to Inconel.

 

Add another vote for 321 SS.

I remember when one of my local intelligence-challenged rotary performance shop owners was dead set on making an inconel intake manifold, as if it had some type of advantage, and was something that he could actually accomplish and sell. We aviation folks had a good laugh at that, especially since his previous work showed that he couldn't even work with mild steel.

I personally only know of one person who really knows how to work with inconel, and he is an aviation maintenance instructor. Apparently, it is not as difficult to use as it seems, but it is "different" from other materials that are more common to the automotive fabricator.

 

If you can weld ss, especially 321, you can weld inconel. Yes I am speaking from experience and I am certainly not a professional welder.
If you've only welded mild steel, get some ss to practice different kinds of welds in different positions.

Your best affordable option is .065 321 tubing and 3/8"-1/2" 308 flanges.

I knew there was a 20b guy out there who had an inconel manifold made but coudn't remember who. Thanks for reminding me 20B 3rd Gen.
How's the car coming along btw?

 

i'd do the intake manifold out of aluminum or carbon fiber if i knew how to work with it...

but i'm a fab noob

 

I have just about everthing I'm waiting on my Haltech, wheels and so other cosmetic stuff. All I lack is finishing the fuel system install and oil coolers

 

just out of morbid curiosity, how much did the 3-rotor manifold cost...$3kish?

 

Well I had a friend make it for me so I only paid for the material and a minimal labor fee, but it was over 1K still

 

got any pics just for fun?

 

Not anymore I recently clean'd out my email and deleted all of them, I will take some more once they are back from HPC.

 

i thought it was becuase it had good heat resistance, or could at least stand heat cycling better than mild steel?

 

Among other things, you thought right.
