Watch this turbo feed itself a rag and die

Incredible long-range suction leads to a very expensive turbo rebuild

Everyone loves a big turbo – they give huge, exciting boost that ramps up and up, giving you the sort of shove in the back you normally only get from startled goats.

One of the less publicised side effects of big turbos is their pure appetite for air – as demonstrated by the giant turbo in this video, which sucks in so much atmosphere that it pulls a workshop rag from over a metre away… and then makes it into a light snack. Naturally, the common-or-garden turbo usually only eats air – and the introduction of a rag slightly buggers it up. This looks expensive…

  • Isn't that how you clean a turbo ?

  • High altitudes affect superchargers more. Turbo boost is controlled by the waste gate. So the wastegate will stay closed longer until the desired boost is reached. There maybe more turbo lag but will make pretty much the same boost. Supercharger suck whatever is available to suck and is run off the engine. Boost is controlled by a bypass valve to prevent over boosting.

    • They’ll be shed loads of lag in that turbo after that 😐

  • So in the paper bigger turbos would be less efficient in high altitude roads like Himalayas, right?

    • Be less efficient that what?

    • I mean it's the comparison between the air density in high altitudes an at sea levels! The amount of work a turbo has to work to suck enough air into I think is doubled at very high altitudes. Maybe it's not that significant or unscientific but...
