This past sunday, I went on a cruise held by the local import tuner scene. It was about a 250 mile round trip, mostly staying at legal speeds but at one point towards the end of the cruise after half the group made a wrong turn, it turned into a bit of a race. We all had turns passing each other at high rates of speed, I for one passed several Civic's in the group at about 170 km/h. My 92 Accord pulled right up to that speed in 5th and felt like it could have kept right on going past that. Anyway, over the length of the cruise, whenever the group pulled away from a stop, we all revved our engines pretty hard in gear, I usually shifted out of 1st and 2nd at 5000 or so. We stopped and started probably 15-20 times, and almost every time, I shifted at 5000. Now here's the thing, after doing that all day Sunday, the car doesn't seem any worse for it, in fact, it seems to be running maybe better. Maybe all that high revving freed up a sticky ring or something, or maybe sucking in all that oil smoke from the handful of Civic's made a difference? What do you think? Could repeated high revving make an engine run better?
