      you have to remember that after only a few races (which last a few seconds at the most) the engines need to be rebuilt.
      Well, after each run, the engine is basically torn down to the block and rebuilt after every run. Including the clutch pack.

      And they do that in less than an hour.

      In fact, here's a video that's NOT sped up, of a pit crew tearing an engine down to the block in about seven minutes.

        So those engines are only good for 1/4 mile between rebuilds, and the spark plugs are pretty much shot before it gets that far? I've had an engine go well over a million miles, and never had to have the spark plugs changed. That's not unusual - in fact, nobody has EVER changed the spark plugs in a C-15.
        Any fool can piss on the floor. It takes a talented SC to shit on the ceiling.

          Well you're also not pushing your engine well past the red line of common sense either.

          And I wasn't certain if it was every run or every few runs so I lowballed to avoid exaggeration.

            Essentially, yes. Unless something really goes boom. And they have 2 plugs per cylinder, if I'm not mistaken...fed by 2 44-amp magnetos.

            Because Peterbilts don't have spark plugs. Am I right?

            Glowplugs.

            And if anyone wants any addition info on Top Fuel...this all seems fairly accurate...

              I only see single plugs in the disassembly video you posted above

              ...Which was really impressive, BTW.

              One is a childish fantasy that often engenders a lifelong obsession with its unbelievable heroes, leading to an emotionally stunted, socially crippled adulthood, unable to deal with the real world.
              The other, of course, involves orcs." -- John Rogers

                Weird. I thought at one point they ran 2 per cylinder. Seems I may be mistaken there.
