Probably more wear on the clutch, but my point before was that a buggy has so much more soaking up the transfer of grip to the drivetrain load such as taller rubber tires and longer suspenstion travel. The slack metaphor used earlier doesn't make for a good comparison. I think it would be more like all that slack would have to be made of spring or rubber to relate to what is actually happening. Take for instance if you plot the physics of this on a graph. On the x would be load, and the y would be time. The load is determined by grip percentage, engine rpm, and weight at the wheels. So If someone actually had a good way of calculating all this math, then my guess would be that if you plot the load on the drive train curve of a buggy has to be a gradual incline over a longer period of time than a 1/8th onroad car. In an 1/8th onroad car, since theres more hp at higher rpm when the centax enages plus more grip available, shorter suspension travel, the graph of the load would be shorter and spike higher than that of a offroad buggy.
