    It's really weird how many people here seem to assume that polymers are automatically worse. Polymers are a vast subset of materials. Much like how gold would make for a terrible metal for turbos, while refractory metals can handle the brunt of the exhaust gases, polymers have their own equivalent. Chemistry continues to improve and I would reserve judgement about the quality of these turbos. The company spent a lot more time researching and developing polymer turbos than most of us. I'm eager to see what they can offer.

    Talk to me when they are used in high performance applications. Number of big hp tuner cars running plastic turbos? 0.

    That said I'll certainly watch this develop but for now there is no deluding ourselves.

    Since we are moving to a world of better emissions, hybrids, electric, etc.., these new turbochargers will be powered by electric. Could be electric stored in battery or these turbos can be driven by an electric motor.
    I'd like to take this moment to correct Altec & anybody else who says this. By definition what the function & how a turbocharger operates, the electric "turbocharger" is actually a supercharger. Superchargers are mechanically driven (most commonly by a belt system, but an electric motor is also possible) vs. turbochargers which are powered by exhaust gases.


    Thank You.


    Otherwise -- Nothing against plastic turbos in a production car. The minute you add performance you'll just throw it out & put on a higher power, more efficient, quicker-spooling metal turbo.

    I do wonder how some people think F1 cars cope with exhaust gasses projecting at the diffuser. These can see 1300 to 1400 degrees and are a composite plastic. I imagine a plastic turbo would cope quite well all things considered.
