Titanium Turbo Unit and Exhaust

Durable and Lightweight. Can be used with the anti-lag system

Titanium can withstand high temperatures. The turbo unit and the exhaust will be more durable if they are made of titanium. You can use the anti-lag system (bang-bang system) without too much damage to the turbo unit and the exhaust.

       Pricetag? $4,000,000,000,000,000,000

       ...and a B2 is more valuable (expensive) than it's equivalent weight in 24K gold, a good deal pricier than titanium.   

       2" OD titanium tubing in 18ga (.049" wall) is about $33/ft retail. 1.5" is $25/ft.   

       If you really want to deal with the heat though, perhaps Inconel (an alloy of nickel, chromium, molybdenum and nobium) is the better choice. It's designed for turbine engine use and certain alloy variants are directly designed for turbocharger and exhaust systems.

       I know the idea of Ti exaust components is widely baked for sport/race bikes. and you pay for it. Don't get me wrong; as an idea, its WONDERFUL. However, there are some major hurdles to overcome to make it work. (price)

       I would think that this type of idea is already baked in racing applications. Not Titanium exactly, but perhaps another lightweight heat resistant alloy, as [bristolz] mentioned, inconel is a good canadate, its used in turbine engines quite a bit. This technology is out of the reach of the average twin turbo 3000GT joe smhoe.... but hey... we can dream.

       I'm new here so I'm a little fuzzy on the terminology, but this is an idea that seems to be mostly baked, but only available in four star restaurants. Titanium is an awesome material for turbos and for exhaust systems. It's lightweight, strong, has low coefficient of thermal expansion, low thermal conductivity, and sounds so much cooler than "stainless steel." For this reason it's used in turbine engines (with much the same demands as the inside of a turbocharger) and in performance exhaust systems. The Chevrolet Corvette Z06 was the first production car to carry a titanium exhaust from the catalytic converter back. However today Ti is still pricier than it's alternatives and it's tough to work with. Those things are changing and a day will come when we can make exhaust systems and turbos out of Ti all the time. But the question is...once we switch materials....what new options will be available to us? What will we be able to do that we couldn't do before?   

       Oh...and the current alloys (inconel among them) offer a wide variety of satisfactory options for turbine material. But we can still hope for improvement
