Check the Bullydog downloader it may be able to remove the top speed limiter.



This thread should bring some interesting responses.....

As far as I know the Bully Dog Power Pup does not remove the speed limiter... However. . When u reach the speed where the speed limiter is supposed to kick in (mine is at about 107mph) the ecm cuts back on stock fueling. . but the extra fueling from the power pup is still there so u keep accelerating... Or u could try a RAD box (racing anti defueler)..... R u at the drag strip when u hit the speed limiter or on the highway?

You did not show a truck model in your signature, but I believe the stock tires on my 03 are rated at 106 mph if I remember right.



Could you imagine death wobble at that speed. :--)

So this summer I was at DYNO day at one of the local performance shops and they had a mobile dyno there and the operator of the DYNO showed my buddy who has a HEMI that once you hit 108 or 110 whatever it is you can crank the key to the try to start position and the starter did not engage but the gauges all drop dead and then lay off the key and mash the pedal down and I watched my buddy takes his hemi up to 134 mph, now he said the cummins will do it too but I previously dyno'd mine just before than so id idn't get to try it. so it does no damage to the hemi and supposably it does no damage to the cummins but I have never tried it so trya t your own risk, but it had the dyno compnay on my print out so maybe I will post the number later and then you guys can give hima call. and maybe verify it, but I saw it work on the hemi.

I rememered you posting that once before, but some how I just can get up the nerve to blip the switch at that speed. Can you imagine if the starter engaged or stuck at that speed. :--) I remember some time ago when someone said you could turn the key back half a turn and eliminate the 110 mph limit also. However when I tried it the truck continued to run, but felt as though it lost power.

So I found my DYNO sheet and it was done by a company called Dyno Tune and Performance (605) 753-1101 I don't remember the guys name but the dyno event I went to was in august of this summer in DUluth Minnesota at a place called Adcanced auto accessories. He might be able to give more details or correct me, he seemed to know a bit about our trucks he said he was a dealer for alot of aftermarket products like FASS, Banks etc...

My '03 topped out at 108 due to the speed limiter, my '01's limiter was at 118.

the RAD box by BD will take care of the 108 speed limmiter. With the Bd RAD box your speedometer won't show over 90 mph, it just goes to 3400 rpm and stops. I hit 111 mph in the quarter, i need to get a GPS and see how fast i can roll until to hit the rev limitter.

 

[Mundgyver]

It is possible to do 131 mph in a Cummins. RPM was at 3200 to 3400. This was not on a dyno and was recorded with a Garmin II+ GPS in the state of Washington, 50 miles South of Ritzville on HWY 395 running against a Mercedes Kompressor on a long uphill grade of 3%. Tires were 285 Toyo's. The ECM monitors the speed sensor via a single wire. Orange and White I recall. I was tac'd out and the Kompressor (one of the smaller ones) could keep up but could not pass. I backed off at the top of the hill for fear of a cop on the other side.

so it would be possible to either cut the wire or put a toggle switch in line? I remember on the older 24 V motors if you cut the limiter wire it would eliminate your cruise control also.



Edit**Never mind, I just saw you have a 24 V. :-laf I thought you were a third genner. Has anyone found a similar wire on our trucks? I know which one mundgyver is talking about.

I tried the key back half a notch also. I have seen the Hemi guys do it at the track a lot. It did what I was told as far as Speedometer and gauges dead, truck still ran, but I noticed my FASS was not pumping. So I maybe you experienced the same thing depending on how your fuel pump is wired. I was not very comfortable with it anyway, but sure would like something to beat the TM crud.

i think you could cut a wire, put you would lose your speedometer all to gether when you would switch it. I think what BD did in their RAD box was put a zenior diode and took a certain about of voltage (90 mph of voltage) and dumped the rest off to ground. I can find out which wires i cut into and let you know. One wire was speedo only and the other was the whole gauge cluster for the torque management override.
