they do.
they're set anywhere from 3200 to 3800 rpm. if you have a tach, it's easy to find yours. just run to truck up to high gear and see where you stop reving.

Of course you could find out your govenor is broken also.
In that case you just let of Mine is governed to 3300 rpm's. I honestly dont think my truck would like to rev much higher than that.

Makes you wonder when the valves on the IDI start to float. I would bet at that point the kaboom wouldnt be far off.

that would be around 4100rpm.
i like doing absolute limit testing
I couldnt even imagine what that would sound like at those RPM's
not on that run. but I do run off the governor on a regular basis.have a vid by chance
there's many local members here who got the t-shirt after they lived to tell about it

well mine must be the 3800 or 4100 level she sits at 3500-3700 all morning(70-85 mph) ... (4:10 ) auto with turbo... funny thing this thing is quiet at that rpms unlike the other 6.9 that sounds like it's coming apart at 2000 rpm I ve got some pics of it let me see if I can find them....
Sounds about right...next time I'm down there, I should bring my video-capable camera...there's many local members here who got the t-shirt after they lived to tell about it
Ouch. I know what the new Superduties sound like flying by with their new 6.4's turning those ultra low rear axle ratios with the big rims at 75MPH. It's a wonder they don't fly apart. That's a lot of fuel being wasted for sure, and a lot of extra wear going on.

well it still gets 11-13 mpg like this running on diesel or wmo...... i've been thinking of putting a 3.55 in it... or swap out my underdrive(locked in high side) for a overdrive...
been thinking of getting ahold of you about a moose pump for the new motor.... but that will have to wait want to replace the turbo and underdrive....

You can use a governor spring from a GM 6.2L that has a higher rev limit...
My international got a lot more driveable when I swapped on a Ford IP. It has a real wide gap between 3rd and 4th gears and it helps to wind it out before the shirt.
