Was that 160mph speed on a tethered vehicle? I remember seeing a Nitro "car" (was little more than a long bullet-shaped car) doing ~200mph, but it was on a tether going in a circle.
Nope no tether. Straight line speed on a 1/4 mile drag strip. I didnt want to post a link to the race results, but if you google "worlds fastest rc car challenge" you will find it.
