speed governor on cummins?

Q: well folks after i get my truck fixed next week i will be heading out of town and into mexico with better and cheaper lsd not the drug that is about $1.80 a gallon next month. anyway i recall some people discussing some years ago about governors on the gas engines limiting the vehicles to 120 mph. even recall some lawsuit. anyway i am wondering if the cummins had it. i want to test the speed of the truck of the long straight roads of he autopistas. i have had it up to 100 for a very short time and it did it without even blinking. i would prefer to do it on the mexican autopista because speed limits are not enforced and its too expensive for the average mexican to use so there is usually very light traffic on these things. my last truck i had was the pathetic v6 w/5 speed. i took it for a test drive on the autopista and it struggled to get to 115. bet dodge did not put a governor on that model of truck ;- .

once again snohead has it wrong. the ecm does govern engine speed but its based on rpm not road speed. iirc the ecm holds the cummins to 3150-3200rpm while in gear and 3250rpm while in neutral. changing tire size in the ecm does nothing to this as the ecm on the isb trucks is blissfully unaware of the res of the truck. the pcm controls the trans shifts and knows about road speed but is unable to control the engine. the isbe common rail may be different since at some point dodge and cummins agreed on common software etc iirc. -- max join www.devilbrad.com and find out what free exchange of info is all about. there are four boxes to be used in defense of liberty soap ballot jury and ammo. please use in that order. -ed howdershelt author on wed 18 apr 2007 012445 -0500 geekboy ner@nerdy.com wrote well folks after i get my truck fixed next week i will be heading out of town and into mexico with better and cheaper lsd not the drug that is about $1.80 a gallon next month. anyway i recall some people discussing some years ago about governors on the gas engines limiting the vehicles to 120 mph. even recall some lawsuit. anyway i am wondering if the cummins had it. i want to test the speed of the truck of the long straight roads of he autopistas. i have had it up to 100 for a very short time and it did it without even blinking. i would prefer to do it on the mexican autopista because speed limits are not enforced and its too expensive for the average mexican to use so there is usually very light traffic on these things. my last truck i had was the pathetic v6 w/5 speed. i took it for a test drive on the autopista and it struggled to get to 115. bet dodge did not put a governor on that model of truck ;- the govener you speak of was places on some models as a safety feature. it was controlled by the ecm and the logic behind it was to not let end user exceed the speed rating of the tires. aftermarket programmers can defeat this limit and in the cause on a truck of mine i simply tell ecm that different tires are present and it changes the speed limit. your vehicle may not have one since its top speed is mostly limited by gear rato and low engine rpm redline. a big gas engined vehicle can go a lot faster top end because of no low rpm redline. ----------------- thesnoman.com .

well this is groovy. i wonder if one can mode their rear-end to have dual selectable rear end gears one for speed other for towing. actually if you have the 3.55s its pretty much ideal for the truck. if you have the 4.10s swap to the 3.55s. -- max join www.devilbrad.com and find out what free exchange of info is all about. there are four boxes to be used in defense of liberty soap ballot jury and ammo. please use in that order. -ed howdershelt author well this is groovy. i wonder if one can mode their rear-end to have dual selectable rear end gears one for speed other for towing. well folks after i get my truck fixed next week i will be heading out of town and into mexico with better and cheaper lsd not the drug that is about $1.80 a gallon next month. anyway i recall some people discussing some years ago about governors on the gas engines limiting the vehicles to 120 mph. even recall some lawsuit. anyway i am wondering if the cummins had it. i want to test the speed of the truck of the long straight roads of he autopistas. i have had it up to 100 for a very short time and it did it without even blinking. i would prefer to do it on the mexican autopista because speed limits are not enforced and its too expensive for the average mexican to use so there is usually very light traffic on these things. my last truck i had was the pathetic v6 w/5 speed. i took it for a test drive on the autopista and it struggled to get to 115. bet dodge did not put a governor on that model of truck ;- .

maybe to you but i can tell when a engine is happy and not and it is not happy at 2800 and sounds strained. oh one other thing.... wheres the hp peak of the latest version of the 5.9l engine think about that one for a minute... heres a hint its over 2800rpm in the 80s i drove a m1009 cucv commercial utility cargo vehicle while in germany. the militarized version of the chevy blazer. though military regs limited speed to 50 driving that speed on the autobahn was way too slow. i would usually drive it at 70 mph. making it the fastest tactical vehicle the military has even to this day. anything above 70 and the engine would start making a loud terrible sound though i have gotten it up to 80 to see how it would respond. not very well. it has the detroit diesel 6.2l v8 with a turbo 400 trans. only 150hp 135 w/kerosene. it had no power. the truck had trouble even going up hills. due to my postion nobody really bothered to ask where i was at anytime. so me and a companion took our vehicles out for test drives. we were one of the first to get the m998 hwmmvs. though the field officers did not want them because they liked their comfortable rides while the hwmmv was very rough and noisy in comparison this would be the first time i took both vehicles through serious off roading. while the other was driving the hwmmv i had trouble keeping up with it. the m1009 just had no power even with it in 4l. we went up some serious hills where the vehicle would barely go while the hwmmv had no problems. after each highway run i would have to hurry and run over and get it washed before the motorpool warrant officer would see the condition of the vehicle. every time after run of above 55 transmission fluid would get pushed out somewhere and end up splattered on the back of the vehicle. .

my 04 ctd goes into fuel shut off around 3100 rpm. for some unknown reason im hesitant to run it over 2500 for long periods of time. anyone know the maximum safe sustained rpm btw my fuel mileage goes to hell over about 2300 in od. al the maximum safe rpm should be listed on the cpl tag on the engine. when towing heavy its best to keep the rpm above the torque peak but below the max rpm. if you climb a steep grade when the rpm falls to the torque peak you should downshift. it sounds wrong to me but thats what cummins says. they made the engine so i believe them. driving technique recommended in the cummins quickserve online isb owners manual cautions do not operate the engine at full throttle operation below peak torque rpm refer to engine dataplate for peak torque rpm for more than 30 seconds. operating the engine at full throttle below peak torque will shorten engine life to overhaul can cause serious engine damage and is considered engine abuse. do not operate the engine beyond the maximum engine speed. operating the engine beyond the maximum engine speed can cause severe engine damage. use proper operating techniques for the vehicle vessel or equipment to prevent engine overspeed. technique the engine produces maximum power at an rpm less than governed engine speed. to obtain optimum engine performance on a grade allow the engine speed to load down to near peak torque before shifting. this will result in an engine operating speed in the maximum power zone after the shift is completed. refer to the engine dataplate for peak torque rpm and governed speed rpm. chart http//i13.tinypic.com/4ckx66s.jpg -- ken .

and youre talking about what in particular please notice the smiley face at the end. anyone who would consider a .357 pistol as a home defense weapon obviously doesnt know a lot about ballistics. again assclown steve you are making and made an incorrect assumption. i never said .357 magnum you did. read the fucking link i sent. hint the part about the clip for the revolver and the part about the holster for said combination was a joke son. hint a sig sauer p229 is a magazine feed semi-automatic pistol. it is either a 9mm a 40 s7w or a .357 sig. if you knew so much about ballistics you would know what a .357 sig was and you would also know that it is no where near the round of a .357 magnum. read the damn link search it on google what ever but be educated before you open your mouth about something. .

actually if you knew what you were talking about you would know that flame speed is a issue because as rpm increases the rate of expansion is not fast enough and the power output is overcome by increased power requirements to pump the engine through next compression and efficency drops off. one word bullshit. all of the above is bullshit. why because its a diesel. so long as you have oxygen the fuel will burn and the expansion of gases will continue. there is plenty of fuel injected to allow the engine to move at 3000 rpm under the rated load. when this ceases to be the case such as when the truck is severely overloaded the engine is lugging. it is said to be lugging because there is not enough power to increase rpm despite increasing the amount of fuel injected. then and only then is your theory applicable. as stated it takes being severely overloaded to make this happen. as to your increased power requirements to pump the engine through next compression statement that is simply a bunch of crap. top fuel engines make enough power to overcome the decreasing pump efficiency despite similar compression and higher rpm than the cummins. iow the decreasing pump efficiency isnt a noticable factor for higher rpm in the cummins as many drag racers can attest when tuning the cummins for 4000rpm. sure you can spin one up to 4000 rpm but torqie will be way down it will be well past peak hp and efficency will be in the toilet so what have you proved nothing. this is also false. peak power levels depend on the fueling curve programed into the injection pump via the plate or the ecm. the most efficient rpm for the b5.9 series cummins is at 1900 rpm according to cummins. however also according to cummins peak power is found at 2800rpm in factory trim. although i do not own a ctd i have driven many and i do agree that it just does not feel happy above 2300 rpm or so. mine feels great all the way to 2800 rpm and ive pushed it to 3100 numerous times. maybe to you but i can tell when a engine is happy and not and it is not happy at 2800 and sounds strained. engines do not have emotions. thus despite the sound it makes at 2800rpm the cummins is well within factory specified limits. it can not only be operated safely but it will deliver power as specified all the way to the rpm limiter. not at all. if you knew thoery you would understand why i said what i said and the dynamics behind it. if you knew reality youd know that 5.9 litres displacement is small. the next step up in cummins line prior to the 6.7 was the c series at 8.3 litres. this doesnt even consider the larger n series or any of the otr diesles marketed by cat cummins or navistar. longer stokes are needed to obtain displacement on there is more mass to balance due to forces of heavy pistons on longer strokes and their inertia as they change direction of travel at each end of stoke. and yet since the crankshaft is larger there is more room for counterweights. the longer the stroke and bigger the bore the more there is to overcome and balance out. this is why the throws on the crank are spaced out at 120 degrees. imagine that perfectly equal throws for perfect balance. for each doubling of rpm the inertia in pistons in increased 4 fold. so if all of them increase equally they are all still equal and thus.... still balanced. btw the reason the new engine is a 6.7 is so they can lower boost to reduce nox formation some. no be mystery here at all. ford did same thing with 6.0 ps who cares thats not your original point nor is it the point under contention. the inline six is inherently easier to balance than any v design. gm and ford likely stuck with v8s for the following reasons not so because as the size bore/stroke of it increased the dynamics of balancing the inertia forces in it become difficult. the mitigate this by reducing rpm when possible. more bullshit which ive already addressed. 1 higher rpm ability thus quicker acceleration when under no load. 2 low hood line 3 cummins was unavailable due to contractual obligation. 4 could be put into vans not just trucks. more to it than thay it would have been a pain in the arse to thry to fit it in and then there is the issue of the 600 lbs more weight up front that many do not think matters. a 1200lb motor if fine in a 2 ton truck that can weight 10 or 12 k empty but not in a truck half that weight. huh the inline six will deliver more torque at low rpm for any given displacement than a v8 will deliver. this is the reason for better efficiency. again you do not understand why. i know why. the reason is because of longer stroke which improves piston to crank angularity for its displacement. if you have a big bore short stroke 6 with same displacement as a v8 it would offer no torque advantange over a v8. your logic is wrong on the reason for efficency i gave no reason f

From : tom lawrence

efficency drops off. sure you can spin one up to 4000 rpm but torqie will be way down it will be well past peak hp and efficency will be in the toilet so what have you proved nothing. better tell that to the competition pullers who are turning their engines to 6000rpm. obviously they do that for the reduced power that they get out of the engine. .
