Duramax Kill No videos, the one night I don't have a camera. I was up at work waiting for my buddy to get off so we could go to the sunday night meets up at quaker steak. While waiting, a newer duramax drives up and dudes girlfriend rolls the window down and says "hey, you wanna race?" My reaction was "race that?" and she says "yea", I point to my car and say "in that?" and she says "uhh yea!". So dude gets out and under the hood and changes the tune (6.6 turbo diesel btw) and we roll out. We get on the highway and run up the road and get off an exit to turn around and get back on the highway. We slow down to do a 50 roll and he honks. He kinda caught me off guard because we were on a curve but on his third honk I went, and put a nose on him. I slowly started putting a few lengths out on him, when I let off I was probably a good 3 or 4 lengths ahead. He followed me back to the parking lot and we talked, said good kill and told me about his tune and how it was just dumping fuel and thats the first time he had ran that tune and how he was only doing 390 to the wheels. Anyways, thought i'd share, kinda excited me since it was my first race in a while, actually kinda suprised me for a bigass truck!!

^^^ Lol funny you should post in here, the truck in your sig popped into my head when he pulled up, and I was thinking "**** this could be one of those super diesels running like 1000+ tourqe and i could be screwed. I think I coulda got him off a dig if I would rolled out and not launched, but he woulda definitley got the nose on me.
Correct me if i'm wrong on your signature, but if you could get a Gasoline engine to hold 63psi it would make a hell of alot more torque than 1300. Dont 400+ CI gas motors on 20-25psi make that much torque? Not being a dick, that just seems like a lot of boost for that much torque, and my buddy is always telling me how much more efficient his diesel is, but that doesnt scream efficiency to me.

He would have gotten slaughtered. He would have dropped it into 4 wheel drive and yarded him! Then he would be chasing him down and hoping he stayed in it long enough for him to catch up! YouTube drag racing deisels: They destroy pretty much everything through the 1/8 mile, then fall on there faces. Good kill though: kinda like a 5.0 Mustang: you never know what you're gonna get when you line up with one... 14.9 or 9.9 sec car? You don't know until they hit the go pedal. Though with deisels it's more like 16.9 or 11.9 sec...
Long stroke engines like a deisel require lotsa boost to fill the cylinder: it's not uncommon for alot of deisels to run 130+psi! For that matter, I coulda sworn I heard stock is in the 60's for some trucks. ?

You could make a gasoline engine strong enough hold 63 psi, but it would be extremely heavy and there is no way to make it hit 63 psi with out severe detonation. Go educate yourself before you sound like a retard again.
You obviously don't know very much about thermodynamics. The compression ratio of an internal combustion engine is directly related the efficiency of the engine. Diesel motors commonly run a 22:1 compression ratio, which is much more than even a n/a gasoline engine could run. For a forced induction gasoline motor, the compression ratio would be even less. Also, there is more chemical potential energy per unit volume in diesel than there is in gasoline. So, when you buy a gallon of diesel,you buying more "energy" than if you are buying a gallon of gas. Diesel engines ARE more efficient than gasoline engines and I could calculate a percentage, but I don't feel like wasting anymore of my time.

Go pull some trailers or some stumps with your big bad truck. He would have gotten slaughtered. He would have dropped it into 4 wheel drive and yarded him! Then he would be chasing him down and hoping he stayed in it long enough for him to catch up!

But, remember, it's not all about boost numbers alone. It's also about the volume and efficiency range of your turbo(s). I could take off my twins and put on a large single turbo and make bigger horsepower numbers with less boost, but it would spool slow as hell. I would even take off the smaller turbo in my compound turbo setup and make bigger numbers. The smaller turbo "chokes" the larger one from puling more volume, but it allows for a very fast spool up. If this truck was used for sled pulling or dig racing, I probably would run a larger single charger.

EDIT: Also read my post above to educate yourself further.
since you overlooked the original statement from his post because you were in such a hurry to make him feel inferior about his thermodynamics education ill rephrase it. your sig says lets see your gas motors make that much boost and that much torque. gas motors can make that much torque(and horsepower) with less than half the boost.(tho i agree they are less efficient) so mabey your sig should just say lets see your gas motor make lots of boost and half as much horsepower as torque, or twice as much torque as horsepower....the second phase would probably suit your ego better
Well My engineering degree covers me for that but it does not change the fact that your truck is less than impressive compared to a 20 psi 400ci gas motor

Oh forgot to mention his friend trying to "School" me on LS1's 
For some reason alot of local SS guys seem oblivious to the fact that all LS1's from the factory have 350bhp. He also claimed that his bone stock SLP car made 390 to the wheels allthough it only ran a 8.6. I really hate when people argue about things when they're wrong, but it kinda entertains me as well.

I guess a 8,000 pound, 700 horsepower truck that gets 19 mpg on the freeway isn't impressive at all. You're right. what was I thinking...
