    17 6.2 Crew Cab Max drive shaft speed when dynoing

    Just wondering what the max safe speed is to run a 6.2 Crew Cab on the dyno so you don't lose a driveshaft. Are you guys doing them in 5th or 6th gear-TIA!

    I wouldn't go over 100mph to be honest.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Determine the critical speed using the estimated wall thickness and length of the driveshaft. Engine speed/gear ratio = driveshaft rpm.

    So probably 5th is my guess.
