  • The Cayman S is about all the car you can use in the US streets.

  • @marky2112 Well.... That's sort of debatable.... I can't imagine using even 70% of the car's abilities without either breaking the law or seriously endangering people. That's why I take mine on the track. So I can explore those upper limits safely and legally.

    caw caw caw

    cough

  • @Zontalim That's called reversion. The engines is actually sucking air throught the exhaust. This happens when you rev and engine up and slam the throttle plate shut. This results in a vacuum in the intake, so the exhaust side is actually 14.7 psi higher in pressure (at sea level). When the exhaust valves open, air rushes into the combustion chamger through the exhaust.

  • @MikeSouzaYT I think he was talking about the birds cawing and the guy coughing haha

  • @agcskates You may be right.... And I went on with a long winded explanation..... (smacks head)

  • @rcjames01 The event to be very careful about is racing down the road and coming up behind another car while downshifting and braking hard. If the driver gets "spooked" they can sometimes hit their brakes simply as a fear response. Then one must really hit the brakes in order to avoid something silly. It happens.

  • I bet the guy in the Jeep is like "holy crap what's the thing behind me???!!"

  • @MikeSouzaYT hehehehehe don't worry, it happens to the best of us

  • @MikeSouzaYT is that why some cars shoot flames?
