Altitude. High or low compression better?

Welcome to the Army Rumour Service, ARRSE

The UK's largest and busiest UNofficial military website.

The heart of the site is the forum area, including:

  1. Disregarding turbocharged or supercharged engines, which will perform better at altitude, a high or low compression engine?
  2. Err......not quite sure, if we're talking modern cars/bikes doesn't the ECM (Engine Control Module - computer) account for variations in atmospheric pressure? Is this the line of questioning your chasing?

    Dunno about the engines. They are out on the wings.
  4. high compression
  5. Maybe it depends what you are driving and where you are? This is at 18,000 feet.
  6. Khardung La! whats an f1 car doing there?!
    I rode a mountain bike up there and bloody hard to breathe. Mind you all the Tata trucks seemed to be getting up there ok. The indian army has a VCP on the top
  7. All very nice. However, does anyone know the answer to the question? :)
