I personally believe the numbers are high for what I have seen for a 6.0 BUT it could be possible if he only has high 600 or low 700 in torque.

we all know that unbroken has seen 150+ mph on the street, so the 160 could be possible, but i know thats in OD or 5th gear aint it? shouldnt the runs be made 4th which is 1:1? i remember UB saying he was at like 4200 rpms and he figured with math that at 4000 rpms he was running like 145 or so so he added the extra rpms, so if he was near the rev limiter in 5th gear at 150 or so, how could another truck in 4th gear be running 160? i just doesnt seem possible, there isnt enough rpms to gear that rear tire spinning 160mph in 4th gear.......

Jeff, I believe it depends on what brand of dyno it is.

It mostly depends on if the dyno operator is smart enough to put reflective tape on the harmonic balancer and zip tie the pickup onto the drag link. Or they can default to mph... You can chose in the dyno program.

I would not know if it is fake and wouldn't get involved either way, but there are dynos in Miami that are known to produce higher numbers than others on the same truck. Based on that I figure it has alot to do with the dyno and operator : I think that's why DJ prefers the track.

Thanks,
Vivian
