Driving Habits
I heard some one say "you drive a diesel different than a gasser" what is meant by that, other than the RPM range is much lower and peak TQ is found at 1600 or so RPM. Sorry in advance for the noob questions!!!

RE: Driving Habits
Diesels are much different. What most people don't realize is that on a Ram diesel, your operating RPM range is a third of what todays gas motors can rev up to. I know the newer cummins rev up a little higher than my 95'. I never take mine over 2500 (I have a 3000 rpm governor kit).
Diesels are long stroke motors for the most part. GM had a few V8's they converted to diesel. Real diesels are inlines.......lol. And a straight 6 can be dialed up to mega hp and torque.
Diesels take a little bit longer to wind up.
Diesels are not fond of winter time.
You have to assume a different set of driving habits with a diesel, in my opinion anyway.
Diesel trucks take longer to stop.
They have ravenous appetites for air. They love the fuel too..........lol.
If I had to condsider the most important part of my setup........ I would choose the turbocharger. A good diesel man knows how to manipulate the throttle to get the job done. Slamming the pedal to the floor is only applicable in some circumstances.
That motor is worthless until you get that compressor spooled up. As soon as you're spooled up, you're ready to do business. If you can feather your gas foot with precision, you can be a good driver. The trick to power is letting the turbo catch up with the amount of fuel that is being introduced into the cylinder. If you open the throttle slowly and steady, the turbo will keep up. You will also retain acceptable EGT's. If you are the kind who likes to press the pedal to the floor, then get ready for black smoke, and undesirably high EGT's.
Driving a diesel to me is an art. I make my turbo sing. I love pulling up along side a struggling Duramax,and touching the pedal ever so slightly. The first thing the Chevy guy hears is my turbo adding about 8-10 extra lbs of boost. The next thing he hears is heavier amounts of fuel being added. Finally he hears that all too familiar "burping" sound coming out of my tail pipe.
And I forgot......he's also having a hard time seeing thru the black fog.........LOL. Sounds cruel but there has to be rank. And there are no Duramaxes at the top. The only way you will catch me, is on the CB radio..LOL!!!!!!
Good luck.

RE: Driving Habits
a gasser's horsepower and torque curves generaly meet somewhere around 5200rpm, a diesel, unless it is highly modified, or a powerstroke/duramax, will never get there. the rotating mass is just to heavy and will end up being slung through the oil pan. gassers make their best power when the torque and hp curves begin to close in, Diesels will never have the hp and torque curves meet, and saying a diesel has a torque curve will get you slapped. frrom 1400-1600 is it roughly a straight line up, then from 1600-3000 it is a straight line, then it begins to drop off from there. the horse power curve is very linear on diesels instead of being curved since horsepower is a dirivitive of torque. basicaly what I am saying is the more RPM's you run on a diesel the more horse power you have, but the torque stays the same. but then again you have the turbo question. pull the turbo off this engine and it would only produce around 150horse.
there are days where I'm not driveing right unless I leave the cars behind me in a cloud of smoke, but then there are those where I shift at 2K and bring the RPM's up slowly frrom there untill I reach the speed I need.
in order for a gasser to go faster you have to downshift and spin the engine up faster. for a diesel you just toss a bit more diesel into the fire to spin the turbo up.
