ORIGINAL: marbro I find it odd that everyone isnt saying both are important, cause what good is a car with 500hp and 120ft/lbs of torque? Yeah so what if you can get up to 200mph if you get to it in 5 minutes. Ideally you want about a 1:1 hp/torq Its just you dont want so much torque that your tires always spin out. When you think about it, your car really isnt going to its potential if your wheels are still spinning out in 3rd gear. Having 500 hp & 120 lbf*ft wouldn't be so bad if you had the right gearing. Trouble is you won't find the right gearing in a normal transmission. That would have to be somewhere above 22,000 rpm. Gas turbine engines ??? Having 'more' torque or 'more' HP doesn't really mean anything, since they're not the same quantity. And the definition of the units is sorta arbitrary. If we were talking in KW & N*M, this wouldn't be an issue. Or why don't we give power in ft*lb/sec? My Accord has 82,500 ft*lb/sec of power!!

IF you take a look at two of the fastest production cars available, the Buggati Vyron and the Hennessey Viper, each has a very flat and massive torque curve, this allows theses cars to reach instane speeds as the torque curve does not fall off until you get way up into the RPM range......

why is this even around dident i explain enough for everyone? both matter equaly without one the other is useless... end of story... and yes gearing matters because when u gear something U INCREASE ITS TORQUE! if u dynoed a car in 1st gear... it would probably flatline any dyno... 400-600 Ft pounds is easily made by ur engine in first gear... 3rd gear is were u dyno ur car... 3rd gear is were it all matters... trust me i work with dynos... im a student at wyotech ;)

you might want to study some more......... having a narrow torque band is useless You ultimate goal is to have a broad flat torque band that covers as MUCH OF THE RPM RANGE as possible. Since HP is a direct relation to RPM and Torque. IF your torque was 100% flat then your HP would raise linearly with RPM. and gearing does NOT give you more torque, it allows you to make the MOST efficient USE of what torque YOU ALREADY have. The trade off is the speed at which you can drive forward at. The only time you actually get more torque that what the engine has is when the car is equipped with an automatic transmission and that is 100% due to the multiplication given to you by the torque converter when the car first starts off. (this is the reason why autos are FASTER off of the line than the same car with a MANUAL)

pl;z plz plz dont post in this again... u have no weight anymore... the TORQUE CONVERTER is mearly a fluid clutch... it in no way multiplies or enhances torque... it actualy destroys torque because instead of a clutch which is solid on solid a torque converter is a liquid turbine that slips 100% while at a stop allowing ur engine to turn while ur wheels dont... when u hit it it creates a vortex with its fins inside the liquid that is transfered to the other side of the converter and then runs threw the automatic tranny... this relationship actualy creates a HUGE HUGE loss in power because instead of the clutch (direct connection) u have a weak liquid... pushing ur car... and if u wanna come back with well why do drag cars use automatics its because they run bracket racing and thats about consistancy not and i make this very clear NOT about top speed or lowest time... a geo metro that runs 50s could dominate in bracket racing because with a good driver it would run exactly the same run over and over and over... now is there any more reasons u think that a auto is better? and if u say anything about the hennasy viper automatic i will stab u in the eye!

you really think you know something don't you? I really hate it when people have no idea what they are talking about and try to tell me i am stupid...... Here read this and then come back http://auto.howstuffworks.com/torque-converter3.htm "In addition to the very important job of allowing your car come to a complete stop without stalling the engine, the torque converter actually gives your car more torque when you accelerate out of a stop. Modern torque converters can multiply the torque of the engine by two to three times. This effect only happens when the engine is turning much faster than the transmission" you are so full of it you stink........ I deal in facts not stupidity........
