Experts: What power comparison is better contained by drag race?
Question:Hp to weight ratio?
-or-
Torque to weightiness ratio?
I raced a vehicle the same mass as mine, he have 235 pounds of torque, but 170 Hp, while on the other hand, I have only 188 pounds of torque next to 190 Hp and his vehicle smoked mine.
I can do 120 mph and he can only do 80. Thats the ensnare. Which comparision do I use to compare the power to weight ratio? Mine tempo his for the first sec, then he swiftly passed me and kept going. We are both automatics.
Please don't shift into gearing, we were contained by our 2-3 gears (on drive) and he is the quicker one. It had something to do next to torque. Thanks.
Answers:
It can't be done without considering gearing.
What make a car get a move on is torque _at the rear wheels_. That is engine torque times gear ratio. And it's complicated because engine torque change with rpm, so it's continually shifting.
There's no easy comparison. You hold to look at the curve of engine torque versus rpm and at the gears used.
Usually the higher horspower to counterbalance car will win, because soaring hp cars make torque at sophisticated rpm and allow the use of lower gears for a particular speed, to multiply engine torque. Having a numerically difficult rear gear is flawless because it lets you use the nouns gears more effectively to stay in an rpm band where the engine is developing better torque.
Sorry if this is complicated and complicated to follow, but it is the way things are. I know you won't deduce it perfectly from this short answer, it's newly to get you thinking nearly the right things. There's a good discussion nearly it in tons books, like:

Racing is rock-hard.
Just because you were contained by the same gear doesn't niggardly the 2 cars are geared the same. Sounds close to your car is geared lower than his. Thats why you time him out of the hole then he comes around you.
He's get you beat on acceleration. Torque = acceleration. Power to mass ratio is based on horsepower. There's a handful of things that could hold slowed you down, besides torque.

Why is 'drafting' a vehicle contained by NASCAR beneficial - but detrimental contained by Formula 1?
Question:The benefit of lower air resistance achieve by closely following another vehcile is easily buried. 'Drafting' in NASCAR, for example, is a central skill, saving fuel and facilitate overtaking moves. However, in Formula 1, this is prearranged as hitting "dirty air". Why the difference between these different types of motorsport? The principle seems to be like...
Answers:
In Formula 1, the cars do punch a hole in the upper air, the "dirty air" phenomenon being in truth turbulences behind a vehicle; this destabilizes the car trailing in turns.
Drafting or slip-streaming is also see in Formula 1, when cars are on a straight beside less than 150 meters within between. It's what commentators call "getting a tow".
The combination of these can be beneficial on a super-fast circuit similar to Monza, or very detrimental within a place like Monaco, where on earth you need adjectives the downforce and stability possible.
Some of this speculation must have started next to thoughts about the ridiculous cost handed over to Fernando Alonso at Monza for impede Felipe Massa, although the distance between them on track was 40-50 m contained by the slowest turns.
It is all down to the design of the wing and spoilers.
F1 designers have cultured their 'art' so much that the cars dont punch a hole in the atmosphere, they cut through it so there is no 'hole for the following sports car to sit in similar to there is within Nascar.
Thats the answer above.
Woah, wrong answer! There is a benefit to drafting, it's just you own to be really really close, and all the guy within front has to do is erect the throttle, and an F1 car decellerates harder that road-cars brake, because of the engine-braking effect, and he can also hit the brakes, which are only just awesome in an F1 motor. Further back from him, the upper air will be turbulent, and you either want to be right within or way out of it.
It's merely detrimental to a Formula 1 car when going through the corners, as the 'dirty air' reduce downforce efficiency and collectively causes the sports car to understeer so the driver needs to progress even slower through the corner to stop the understeer.
In NASCAR the aerodynamics are not as intricate as F1 and the cars are designed to draft. Also many of the tracks are bank it's almost like driving surrounded by a straight line so the cars can draft through the bends.
Nascar is full-bodied so at hand is a slipstream behind them.F-1 is approachable wheeled and the heavens does not flow off them within a way to create a slipstream.
Insomniac is on the right lines, no pun intended, oodles teams surrounded by F1 are thought to tune the aero to intentionally make a turbulent wake up that would `steal` the air from the wing of a following competitor.
In NASCAR competition the aero rules are more basic and the shape of the vehicle allows a longer `hole` in the atmosphere for a following car to sit surrounded by. The `hole` is a partial vacuum and it sucks the following car along, thus allowing the slingshot effect for overtaking.
drafting contained by NASCAR equates to getting a tow in F1
the difference is that F1 Generally go faster, has a much more intricate course to steer, and vastly different speed variety.
you will get NASCAR style "drafting" on a long straight when someone requirements to overtake, but doesn't have a subtantial speed / power benefit over the leader. however what little overtaking that go on in F1 is usually by outbreaking the influential car (ie entering a corner faster, departure the breaking later, and hoping to convey that speed through the corner.
however the points made earlier are valid F1 cars are designed to cause as little aerodynamic impact as they drive (to improve speed, dwindle fuel usuage etc.) They use wings & other aerodynamic structures to acheive this (NASCAR uses bank tracks do a similar job). F1 wings would be significantly compromised going through turbulent nouns, and would mean lower speeds going through corners, and poor handling (incorrect twist settings can cause spectacular problems (eg the Mercedes crash at Le Mans surrounded by the 90's (at 1.14 on the clip))). NASCAR cars are aerodynamically very set.
The differences probably reflect the origins of the sport. In Europe the trend be to smaller more agile cars, the US tended to dance for large "power" cars (in abundant ways similar to road cars). The handling of US cars on European roads is / was a quip when corners and pop up, the brakes dont work, some of them are pretty scary contained by the US...
NASCAR is sponsored by the car manufacturer who want something (bodyshell wise) sort of similar to the cars they sell and a spectacular show, F1 have always be about out and out speed and engineering excellence, not neccesarily selling cars, although coup¨¦ manufacturers own always be involved (Lotus, Ferrari) and are becoming more so (Mercedes, McLaren, BMW, Honda, Toyota). NASCAR is mor eabout selling cars and being a TV / grandstand spectacle
yer pays yer money, yer take yer choice.
in my belief F1 has become amazingly very boring (liitle overtaking, little action)
NASCAR newly looks dumb.. especially the frequent shunts
I prefer tin top racing (Touring Cars... very soon that is a spectacle and things develop on a varied track so driver skill, a bit than bravery is critical)
cars in NASCAR are designed surrounded by such a way that they enjoy higher tolerance to the so call dirty air generate by drafting. this design is essential due to the nature of the sport of close endeavour racing.
formula 1 equally can benefit from the principle of drafting as well but not within a long duration. a number of things can dance wrong if they opt for drafting in an extended amount of time. a highest concern is their cooling systems, this includes engine, brake and even electrical cooling system. they're designed to gasp for verbs air contained by order to be important. another is the whole aerodynamic packet of the car, cars behave differently almost wildly if they get close satisfactory to the car within front.
if you watch formula 1 closely, you will go and get to see drafting being done on various occasion during the see but it is oftentimes only done surrounded by straightways attempting to pass the driver surrounded by front . in an event that the driver ruined in his overtaking attempt, the driver simply back off a short time ago a bit as they reach the first corner. he will after use the whole nouns to get close again as they approach the exit of the final corner overriding to the straightways then start the undamaged process of drafting again.
Shape of the car. F1 begin wheels, which affects the steering.
