  2. Re: gmc 2500 4x4x turbo diesel all the way

    i have a question since you seem to know about diesels, why do diesel have so much torque, and what is torque anyway<!-- Signature -->
     
  3. Re: gmc 2500 4x4x turbo diesel all the way

    torue is the pulling force behind the car, it's directly linked to the cars acceleration
     
  4. Re: gmc 2500 4x4x turbo diesel all the way

    How about the BMW X5 Le Mans. V12 straight out the winning Le Mans car, good for about 700 odd horsepower.

    Well, not a real race car, just a concept<IMG SRC="http://www.supercars.net/servlets/cMsg/html/emoticons/smile.gif"><!-- Signature -->
     
  5. Re: gmc 2500 4x4x turbo diesel all the way

    the X5 isn`t a truck-i`m talking about the big american rigs. oh yeah my truck already has a turbo -i think all diesels do! i think the plow has sum aerodynamic affects though
     
  6. Re: gmc 2500 4x4x turbo diesel all the way

    so, about torque.. is it good to have a lot?

    Horsepower accelerates a car, not torque. Torque can be produced without the wheels even moving (ever tried to pull a stump out of the ground with a 4x4 truck?). To accelerate a car, the wheels have to move (duh) which introduces rpm into the equation, and hp = lb-ft x rpm / 5252.
     
  8. Re: gmc 2500 4x4x turbo diesel all the way

    Torque is in fact related to a car's acceleration, I would say even more than horsepower.
    The mathematical definition of torque is
    Torque = Force*Length

    In the case of a car the length is the radius of it wheels.
    However, I actually don't know why diesel engines produce so much torque at so low an rpm. Anyone can say something usefull about that?
     
  9. Re: gmc 2500 4x4x turbo diesel all the way

    torque is the spinning force put out by the engine. the more torque you have, the more you can tow. diesels are high in torque cause the are bigger than gasoline engines, so the crankshaft has a bigger spinning circumference(or distence). thats why the old chevy 454s and 427 big blocks had a lot of torque<IMG SRC="http://www.supercars.net/servlets/cMsg/html/emoticons/smile.gif"> the turbo is there because normally asperated diesel engines don't tend to produce that much horsepower, so the turbo commes in handy in that department.
     
  10. HA HA HA HA HA HA HA HA HA HA you guys are hilarious

    you get torque from a long stroke motor u idiots . . . . . . diesels have long stroke to compress the air before diesel fuel is injected, that's why diesels got torque <!-- Signature -->
     
  11. Re: gmc 2500 4x4x turbo diesel all the way

    um excuse me did someone say that torque is more related to acceleration than HORSEPOWER?? may i remind you that the horsepower equation is hp = torque * rpms / 5252 so in fact horsepower ALWAYS WINS?? your going to tell me that if i pit a 290 hp car vs. a 300 hp car same weight same drive ratios/gear ratios/ that the 300 hp car (if it had less torque) would LOSE?? is that what your saying? because if it is than there is something seriously wrong with your thinking. horsepower is a number for a reason they dont just make it up and say that its a measure of a car's power. you can have all the torque in the world, but not move one step...you might have your torque equation (torque = force * length) but force is no good unless it is accomplishing work. You can have a lot of force, but not move something.

    Its exactly the other way around, torque accelerates a car but you'll need horsepower to keep it going when you exceed certain speeds!

    torque is what moves the car from a start horse power takes over at high rpm this is why the zo6 out accelerates the 36 modena they both make about 400 hp and the ferrari is lighter but the zo6 has 400 lb/ft of torque to the ferrari's 275 whichis why the zo6 runs the 0-60 in 3.9 secs and the ferrari is capable of just 4.3. <!-- Signature -->
     
  14. Re: gmc 2500 4x4x turbo diesel all the way

    ok so you say that horsepower is high end power? that's what your saying. may i remind you that from my figures the z06 you talk of doesn't out accelerate the modena. the modena does 0-60 in 3.8 from motor trend...and in addition its quarter mile is 12.2 thank you very much which ties a viper. the new 2002 z06 has 405 hp and does the quarter mile in i believe 12.6? and its 0-60 is still 4 something. i got this information from both car& driver AND motor trend. so that's my source.

    in addition even if what you said was true (assuming your z06 assumption is correct) it still isn't correct. the reason why the z06 would have a leading edge is because

    horsepower = torque * rpms/5252
    i dont know the torque curve of each so i'll make one up

    suppose the z06 at the low end (3000 rpms) makes around 350 lb/ft of torque and the ferrari 360 modena makes around 130 at the same time.

    by substituting this into the equation at the particular rpm (3000), the ferrari makes less horsepower than the z06. so in turn you assumption is not correct that torque is what powers a car at low ends and horsepower at high end.

    the REASON why horsepower is always at high end is because when choosing horsepower and torque numbers people pick the HIGHEST number meaning that if a car hit its torque max at 6000 rpms. THAT WOULD BE THE TORQUE NUMBER.

    obviously you didn't read my thing closely enough or you wouldn't have this problem comprehending my words. HORSEPOWER POWERS THE CAR TORQUE IS HOW HARD ITS PULLING. HOWEVER YOU CAN PULL ON SOMETHING REALLY HARD BUT IF IT DOESN"T MOVE IT DOESN"T REALLY MATTER.
     
  15. Re: gmc 2500 4x4x turbo diesel all the way

    wut the hell guys the poor kid just asked if it was good to have alot of torque -yes it is and yes torque does accelerate the car/truck
     
  16. Re: gmc 2500 4x4x turbo diesel all the way

    Im only 12, so dont blame me if im wrong but i believe that horsepower is a direct figure generated by torque, from the equasion hp= lbs.ft x RPM /5252. torque is the pulling force in my book, and horsepower a measure of this force at a certain rpm.
    Lots of torque is great unless you dont want to smoke your tires every day drving to work. so it really depends on your driving wants/ needs.
     
  17. Re: gmc 2500 4x4x turbo diesel all the way

    i was dont diss cars u can`t have but i lost my pass word----besides how did we get on about the torque we where talkin about the 2500!!!!!
     
  18. Re: gmc 2500 4x4x turbo diesel all the way

    dammit you should read the #$%#in post next time of course its good to have a lot of torque I NEVER SAID IT DOERSN"T BECAUSE TORQUE CONTRIBUTES TO HORSEPOWER. you can have 10000 lb/ft of torque at 0 rpms and have 0 horsepower. all i said was ultimately horsepower makes the car go faster. you should read my post next time ask any car expert and they'll tell you the same
     
  19. Re: gmc 2500 4x4x turbo diesel all the way

    see even a 12 year old knows the shit from my explanation.

    point given: a formula 1 car generates little torque but has a huge horsepower figure your saying it has a slow start?
     
  20. Re: gmc 2500 4x4x turbo diesel all the way

    someone made a stupid comment besides on the original issue there is a lemans "truck" the bmw x5 lemans 700 hp v12
     
  21. Re: gmc 2500 4x4x turbo diesel all the way

    ooooooooooooo u sutupid kids piss me OFF READ ALL THE POSTS BEFORE U POST !!!!!! the X5 lemans isn`t a TRUCK!!! its an suv!!!

    actually, bmw did with the bmw x5 4.6is made it 700 hp was it?
     
  23. Re: gmc 2500 4x4x turbo diesel all the way

    right but suv's are traditionally derived from truck chassis and engines although i would highly doubt that for the bmw x5. also i put truck in quotation marks because it doesn't exactly fit the category. andi believe there is a bmw concept that is basically the x5 with teh back chopped off so it looks like a truck.

    I am almost positive it's sourced from Chevy, although with different part setups. Its not like the V8's they sell here.
