Good lord.



You don't have any respect!



Personal attacks are no way to make someone see or respect your point.

 

EXCUSE ME!!!!!!



I GUESS YOU DIDN'T GET THE MEMO...... AS STATED HERE, Memo 48-623a Section2, CLEARLY STATES THAT "SOYLENT GREEN" MUST BE AN OPTION IN EVERY NEW POLL......



REMEMBER NEXT TIME.......

 

yeah i dont follow memos...memos = gay

 

usually a bigger engine is designed from a smaller block. For example, a regualer chevy 350 v8, then you can put a stroker crank in there, and make the displacement 383, giving you more hp and torque, but not adding weight. Another example of this is actually the new s2000, they stroked the motor from 2.0 ltrs to 2.2 ltrs, giving the engine more torque, but not adding weight. Another way to add power is to bore out the cylinders, which would make a bigger displacement, but actually loose weight. So, basically my point being is hp and torque are relative to the displacement of the engine, not the actual size/weight of the engine.

 

It's more a case of striving for a light car rather than one with low torque. My car will have a torque per tonne figure of 140lb ft/tonne which is roughly the same as the new Range Rover 4.4l which I think is high enough (if not too high). Bear also in mind that I will have a power to weight ratio of 270bhp/tonne and the ability to go round corners like - well like a 1100lb sportscar with double wishbones all-round!

I believe he was attacking your reasoning, not your example(your car)....I agree, your car doesn't need that much torque, but your assuming that the more torque an engine has the bigger and heavier it is, but i already gave a response to why that reasoning is false.

 

Almost all street engines will produce a torque per litre figure of around 70lb ft/litre to get it much higher than this (ie 80lb ft/litre) is not only very hard but will almost certainly produce a car that is a pain to drive, even fully blown race engines will barely exceed 90lb ft/litre. Exceptions to this rule are turbos, but essentially they increase the size of the combustion chamber and add at least the weight you save with the smaller engine.





Obviously there are certain engines out there that are nowhere near the amount of stress they can be placed under - the Skyline engine is a good example of this, and can be bored out to nearly 3 litres but then again the Skyline engine weighs a tonne and has needlessly thick block walls. But you can only bore out an engine so far, obviously.



Put it this way if you can get a n/a civic engine to produce the same torque as a chevvy, and have a drivetrain to handle it weighing the same I will eat my car.

youre all ******* wrong





i am torque

 

your missing my whole point, torque is relative to displacement, not the size or weight of the actual engine. right?

 

my displacement = my torque...
