Re: Muscle Cars vs. Vtec.....

  1. Vette Pro is correct. Also, Vette engines sometimes weigh less than their smaller displacement competition.<!-- Signature -->

  3. Torque is not reserved for heavy trucks. A diesel semi truck's motor and a muscle car engine have absolutely nothing in common. Truck engines lack HP, so they cant go fast. Muscle car engines lack no HP whatsoever (that NASCAR/CART comparison proves nothing, you should try comparing supercharged drag engines), so theres no lack of speed. That low-end torque just assures that the powerband doesnt die out below 5000rpm.

    hmmm..what you're saying makes sense. Glad you make that clear. Me bad. Me wong. :p <IMG SRC="http://www.supercars.net/servlets/cMsg/html/emoticons/smile.gif">
     
  5. yea the ferraris are badass but i still would have to stick with my SOl when it hits the vtec pt at 2700rpm its over its badass to see it rev to the 12000rpm redline yes 12000redline this is from a newly modified mugen superchip it was pretty damn expensive but its worth it ($5500) i love this car its the best ...now what !
     
  6. idiot. horsepower always wins. if two cars are raced one with 290 hp and one with 300 hp and geared the same way the one with 300 hp wins no matter how. i encourage you read what horsepower is comprised of. secondly honda is not the only car to use v-tec which is quite common in today's more advanced vehicles. thirdly the reason bottom end torque is low is because of the engine displacement, and v-tec actually helps boost that vs if you used a differently sized cam lobe. now hondas with v-tec are far from revolutionary and the whole tuning civics thing is stricly an american thing trying to duplicate japanese tuning which by the way honda does not domininate (in japan).

    v-tec basically works by having two cam lobes which are interchanged during different rpm operations this ensure better torque, breathing, and cam timing..anyone who needs to why you need to time your cams ten you shouldn't be here.

    torque although the physical effect is more effective in teh higher rpm areas. however its no good if you can't ca horsepower = torque X rpms / 5252 as you can see rpms is always larger thereby instigating a more dramatic effect. although low end torque is always good having a higher rev lmit lets you take advantage of gearing to power you vehicle down the 1/4 mile stretch. why because as soon as it hits the torque peak torque goes down...versus if you build up to your torque peak. also a car with less rpms will have to shift sooner thereby reducing power while the toher car is still in the previous gear. this does not mean a honda civic will outaccelerate a corvette but you should get the idea...that if a corvette revved higher..(see?)

    although the corvette is a good vehicle superior to most american ones it is by no means godly in terms of modern engine technology. i do not understand they use of pushrods which limits revving and efficiency when they had a perfetly fine lt5 engine 10 years ago....
     
  7. i have posted this in two of teh corvette forums because clearly there are some misguided things. as for nascar and cart?? cart revs to 15000 and is aided by a turbo. nascar is uh kinda boring....a constant left handed turn.... you can't touch formula 1 or world rally no matter how you put it and i'm sorry to say this the corvette is a good car ( i wont deny you this because i drove one like 2 days ago it was amazing) but simply doesn't stack up in comparison to what a more modern engine of similar displacement could accomplish. what's the displacement on this sucker 540 hp? so you going to say to me that you'd rather hae more torque and generate 350hp and somehow object to the corvette having 540 but less torque? that really seems misguided
     
  8. Actually HP is just Torque calculated over time. TORQUE is what matters. That is the pulling force you feel when you slam the pedal to the floor. It is the measurement of the force of the twising motion of the engine that moves the car a certain distance. If I were building a car (and I am) I would look at the Torque specs through the RPM range rather than the HP numbers, because that's what matters. If you can make torque up high, you're going to make a lot of HP because again, it's just a calculation taken from the Torque numbers.<!-- Signature -->
