What is the cost? Inconel is used extensively in water-water u-tube heat exchangers because of strength, high temperature stability and most importantly corrosion resistant. Nuclear power plants use inconel to reduce corrosion that can be activated (made radioactive) passing through the reactor.

A waste of money for all but professional racing applications in my opinion.

Speedlimit..

 

at the exhaust port it was pretty good but soon after it cooled down really quick( ala carbon carbon brakes)

the nice thing about these was you could do some wild compound curves and have expansion chambers where ever you wanted. but i think the cost/ reliability was too great so they went back to inconel or some unobtanium setup.

sure was fun to play with that tho

Hey, I used to manufacture Inconel exhaust nozzles for the Pratt & Whitney V2500s (25,000 lbs of thrust). Drilling the parts was hell on all types of drill bits... even using automatic Quackenbush pneumatic drills. I have no idea what it would be like as tubing. Even back then the engineers raved about the durability of Inconel. That was a long time ago though.
