what's your top speed?
just curious what ya'lls truck's top speed is. i'm sure everybody's tried at least once 
I got the opportunity to play around with another cummins on the highway a few days ago with some interesting results. I have not idea who the other guy was but his truck was an 01-02 2500 sport definately bomded. we gave each other a mutual thumbs up while on the off ramp.
I ultimately found out that my truck goes 109 MPH. that's it, it runs out of rpms, i tried for what seemed like miles to get it to go faster but it wouldn't. Oh well.
how fast are u guys running?

117 at 2700rpm in 4th gear. The truck started defueling. Need drag comp to make it go faster. Pretty impressive considering I'm lifted 4.5" and run 35's. I guess the 3.54 gears in the rear end help.

Yeah I have about the same set up. done up to 100 before lift but i don't see a reason now. did 160 on a honda cbr 600 once, never again.

Believe it or not; i havent opened mine up yet, and ive had it ever since i have had my liscence which was 16, and im 18 now. Some day i want to, but i just havent done it yet. I feel like it would do around 120mph. 3:54 gears, .69 overdrive in the auto, 285's, and a 3k GSK. Id hate to know how fast it would go with a 4k 
It will pull to about 3200rpm's if i tighten the governor springs a little. Id say 120 should be about right. Thats dang fast for a 7k lb truck

Just messing around one time I had my '01 up to an indicated 115 during a 30 second blast on the service road to the Bonniville Salt Flats. Still had more in it, but the road was too rough for that speed.

Up to 105 and climbing put I had to let off. Wife saw how fast I was going 
I was barely losing a race to a Chevy gasser towing an empty 6' utility trailer..............
..............I was towing a 18' open car trailer with a 70 Newport on it.
However it did take him a while to start pulling on me.
