Duramax Puttin the Hurt On Everybody I pulled up the street races last night and everyone is ranting and raving over this duramax work truck there. I raced it and proceeded to get my *** thoroughly waxed. He then proceeded to desimate a c6 vette. Then a low twelve second ls1 trans am. Then a new 5.0 stang. Then finally my buddies showed up in their foxbody and beat him by a small margin (1-1.5 cars). That foxbody runs bottom 11s.
Diesels continue to amaze me over and over. I'm not trying to be a dumb redneck, but it is amazing that a lifted truck on 35s with a toolbox and a brush guard can pull trailers all week, then go to the strip and run 11s. That is a true multip-purpose vehicle. Of course, I wouldnt choose a duramax, but thats a different issue.

Horsepower is what makes you fast, not just torque.
If you can't spin the engine fast enough and/or flow enough air at higher RPM, you aren't going to make much power, and consequently won't be all that fast.
This particular diesel is fast because it can flow tons of air efficiently at a high enough RPM to make tons of power. To make a high torque number, you just need to fill the cylinders with lots of air. To make a high power number, you need to maintain that high torque as much as possible as the RPM rise.

Uhh...what?

hp=torque*rpm/5250
torque is the actual force that your engine produces (makes the car accelerate), which is exactly "what makes you fast"...

I think what he's getting at is that all that torque at low rpms and not spinning the engine to maintain that torque at high RPMS isn't going to make you fast. Plus the fact that diesels are really heavy. You also have to consider that it takes a Diesel truck like that about 1000 ft/lbs to do a low 11 ET.

I've seen a few modded diesels that were that quick and the owners claimed to have a LOT of money in them.
Those couple make the idiots with nothing but stacks and programmers think they're fast though, makes for amusement and some all you can rape redneck buffets.

Yeah Mr 1992tsiawd, please keep your "knowledge" to yourself. This is not a HP vs TQ thread. Diesel make gobs and gobs of TORQUE and rarely see anything over 5k rpms. zz4 said it best. Torque is force.

lol at HP being what pushes the car....apparently along with Ricer math there is also Ricer Physics. a diesel engine will rape you 10 ways from sunday in a 1/4. a cummins or duramax if you could fit it into a light truck or car...you would destroy anything on the street once tuned. you dont need to be screaming 8000+ rpm to make power... typical import owner who thinks topend, peak HP and trap speed and roll racing is where its at..

its not the fact that its a diesel, its a turbo. ANY turbo will run like that. and as a matter of fact ANY TURBO 35psi 6 liter gasoline v8 will murder a 35 psi diesel.
and a stock GT3788VA turbo(lb7) is capable of 850rwtq. the trans cant really handle it. for long.

horsepower is the definition of work produced over time. torque is the measure of twisting force. any work produced over time IS horsepower. Horsepower IS what moves a vehicle NOT torque. strictly by definition.
torque is and instant value. it is spread across an rpm band for a series of instant values. the work (HP) that moves a vehicle in (calories/hp/watts) is the measure you speak of.
