I don't normally speed around in my underpowered oversized tire rig, but last weekend between Denio Jct and Winnemucca, NV we hit the limiter in my bro-in-laws '03 4cl (stock tacoma) at 104 mph at just over 5k rpms. Me being the streetbike variety said it was probly a 5th gear rev-limiter. So we ran up to 104 in 4th (don't recall the rpms on that one, but it wasn't redline) and sure enough ignition cut again. I'm not a flagrant speeder, but this is seriously the middle of nowhere. I think one stretch is about 30 miles, not turns, no trees, just sagebrush.
