I love those guys. They don't come on the aerodynamics forum with extraordinary and inconsistent claims.

Actually I don't tig weld and I have never tried it.
I have passed bend tests with fcaw, gmaw in flat, verticle and overhead and smaw in flat. I think that's decent since I have never been a full time weldor.
I have mig welded with titanium. Its a lot like welding stainless, but with more prep work.

I just don't like how with a gasoline engine you are always fighting isobaric expansion. Your pumping losses at the throttle body are going to be around 2 horsepower on a small 2.0L 4cyl engine and there are lots of really complex ways to try and reduce this. Or you can go with a tiny sub 1L engine and run it wide open, but then you are limited to sub 1L power, okay for a car, not useful in other applications.
I would rather just eliminate the isobaric losses all together.
