Anybody ever redlined there ALH shifting or had their TdI at top speed ? The speedo says 140mph and redline is 5200 rpm's.
Whats that translate into MPH at 5200 rpm. Just curious in case I have to escape a Cowpoke or a Chupacabra

I’ve hit 198 km/h but that was on the old K-Tech tune. Not sure if they’re governed from factory.
Holy Shiite thats 123mph . Amazing. I rarely go more then 80mph. Usually 70 on cruise control. Every now and then 90mph . I do an Italian tune up from time to time rapping it out to about 3500 rpms every now and then . Speaking of Italians I says to my mother in law , when is it ok to spit in an Italian womens face ? She says I dont know , I says when her mustache is on fire haha. Now I sing Soprano

"Channel 18:

  • On some EDC-15 ECUs, this channel has a non-zero value in it like 190.
  • Yes, that's the "speed limiter". Don't mess with it!
  • It can only be adjusted downward, and it's one-way! You cannot increase the value, and if you decrease it, you're stuck with it.
  • So unless you want to permanently decrease your car's top speed, Don't mess with it!
  • If you do mess with it and your car ends up with a lower top speed than it had before, don't call us, don't e-mail us, and don't complain that we didn't warn you

    ≥This≤ is what I was thinking of. Not sure what all it means but it is on Rosstechs site. I just assumed they were limited, not saying I was right. 198 is pretty awesome @J_dude

I’ve always thought these cars with a taller 5th, bigger turbo and ect would be pretty darn surprising on the autobahn. Pretty sure they’d have the power to get you to 250kph. Someone could math it out with ratios. @IndigoBlueWagon probably has a good number as he has tracked a number of these cars.

When my 99.5 was new it got redlined all the time, seemed to feel like the valves just floated beyond redline. Drove for many years after.

For some reason In my head I had over 4K rpm’s as the magic number to exceed.

I’m imagining Mater saying this as I write it...”ssshhhaaayyyy 3500 ain’t nuttin’..., I used to set the cruise on my sbc at 3450 and let her eat.....” (not counting converter slip) 12+ hrs at a time. 80 mph and 12 mpg:ROFLMAO:

1988 V2500 Suburban, 355 sbc, TH-400, 4.10 gears, 32” tires.

Yeah I don’t do that often lol, I was testing things out that time 😉

Same here usually, depending on the speed limit.
Well today I was on the Crosstown expressway in the far left lane cruise control on 80mph . I was moving along at a pretty good clip. Watching the side traffic and one car behind me at a pretty good distance . A car in front of me quite aways up the road. The car behind me didnt look like it was moving up on me.
Well I guess I wasnt moving fast enough although Im passing traffic . This guy behind me speeds up and he whups out to the right and hes gonna cut me off between the car in his lane and me in the fast lane. However theres a car in front of me thats doing about 70mph. So I let off the throttle , he cuts me off in a cars length I nail him with the airhorn. He has to hit the brakes so hard the back of his car comes up and his rear wheels are skidding across the pavement so he doesnt hit the car in front of me!
Then he instantly whips across three lanes of traffic at 70mph and exits right, barely making the exit
Im flabbergasted ? What just happened ? This isnt road rage , theses are just idiots!
I need more horsepower. Or a horse and buggy

I've never red-lined any of TDIs .... hardly ever drive faster than 75. Mostly, I hang at 70 and below. Let the left lanes roll is generally my policy.
I hardly ever take the RPMs past 3600 when going through the gears. Shooting up to 3200 to 3600 RPMs briskly while going through the gears is more than enough to keep the oil accumulation to a minimum in the Inter Cooler.

Im with you there AndyBees , I try to drive conservativity and in that range 70-75. Shifting too. Very seldom do I get to froggy on it
