Horsepower vs Torque

[TopEngine]

Toyota - T for Torque
Honda - H for Horspepower

mas kailangan ang torque lalo na dito sa atin na kailangan mag-overtake. vtec is great pero matagal pa bago sumipa (at higher rpm range meaning you'll consume more fuel) and that delay in time for overtaking is a matter of life & death kaya mainam na as much as possible mababa ang peak torque like with modern day crdi, kapag tinapakan mo bigay agad ng power when you need it.

What I do when I overtake, I shift gear 1 down then gear 1 up when I feel that I got the right rpm, I hear the VTEC kicks in

BTT: basically it's the Torque

The high-revving nature of the Hondas don't necessarily mean malakas sa gas.

The R18A on the Civic actually has decent mileage. Also, even without having to use the upper rpms, kaya namang magovertake. I rarely found myself needing to go past 3000 rpm with an FD. Sa bagal magdrive ng mga tao, di naman kailangang flat out para makaovertake.

kaya pala hirap si CIVIC ek ko sa bundok
mababa pala ang torque..

how about trailblazer vs. fortuner?
balita ko mataas daw HP ng trailblazer

[kinyo]

torque sa akin ... aanhin ko ang hp sa city driving?

accdg to my OBD2 scanner, my diesel suv use only 25 hp while cruising 100 kph ... it doesn't really take much hp to keep a car in motion, but having more torque will make moving the car easier

yup gaya ng namention ng isang post dito, yung mga civics ng 90's-early 2000 ang nagsusuffer sa low end power but yung mga fd ay di na gaano

Read this explanation somewhere: hp is like a sprinter--it gets you there faster but slows down with more load. More torque means it can move at the same speed with heavier load but it's not necessarily fast.

My interpretation: You need more hp if you like driving fast with less load, and more torque if your car is usually at full load but you don't need to drive fast. More hp = mas mabilis. More torque = mas malakas ang hatak.

Torque is more fun, especially when you're pinned back on your seat.

.....to a certain extent. Too much torque isn't good either. Back when I had my turbo Diamond Star, my roomate got sent overseas. So, he left his 5.0 Mustang LX with me while he was gone. It's so torquey compared to my car, I kept spinning the tires when I took it out for a drive.

Mga sir makikisawsaw na din po.

Para mas simple ibukod natin ung engine alone hanggang sa flywheel wag natin sama iba component engine muna.

Hp and torque are directly proportional to each other. Parang magkakambal po oyang dalawa na yan.

Nagvavary lang kasi different engine perform differently.

For example honda 6000rpm max power out put ibig sabihin yan ang max torque at hp niya.

Nagiging complikado pagnasalpakan na ng transmission dahil sa gear ratio.

So technically bigger engine can produce bigger hp and relatively higher torque.

Nagkakatalo lang sa configuration ng gears sa transmission and/or gear box.

Hope this helps.

By the way on a mathematical standpoint hp is determined by the torque multiplied by the rpm - i hope i recall it correctly from my thermodynamics class.

About gear ratio, mas maliit po ang gear mas mababa po ang torque. Kaya ung iba feeling nila mahina humatak ang vtec (stock lang ha walang iba confi) kasi maliit gear eatio niya at mas makakaproduce ito ng speed.

Parang bisekleta lang sir at constant rpm bigger sprocket and main plate combi is lighter on your feet because it has bigger torque but speed will suffer kahit tulinan mo padyak mo hanggang dun na lang iyun. Pagniliitan mo naman ung sprocket tutulin ka pero mabibigatan ka kasi maliit ung torque na napoporduce ng sprocket naniyun kaya yo u need to exert more effort.

Hope this helps mga sir.

this is the equation most tuners used to predict wHP during dyno runs...

HP = T x 4000
-----------
7120

Where:

HP - horsepower
T - torque, Nm (engine torque mapped in the ECU)
4000 - RPM
7120 - constant

HP to be multiplied with 10-12% (FWD) and 15-20% (RWD) for loses in the drive train.

[niky]

5252 if you're talking foot pounds.

And more precisely, 7121 for Nm.

-

Drivetrain losses are nothing more than ballpark, nowadays. With some cars using ultra low-friction drivetrains, you can't assume anything. The Nissan GT-R boasts some 10-15% losses only versus something like 20-25% losses for STIs and Evos.

And then you get to the problem of dynos calibrated to different standards, SAE (over)correction and etcetera.

[Helios]

used to be a big deal back then, but engine tech has matured since and microchips and control systems have increased performance and fuel economy. our road going cars benefitted much from f1 and other track cars.

now going full electric...

HP is how fast you hit the wall,
Torque is how far you take the wall with you.

hehehe

[Retz]

Hindi ba comparable sa gasoline and diesel engine? If you need more Hp then sa gasoline ka but if you need torque sa diesel engine naman.

Mas maganda po paliwanag ni sir niky kaysa sa akin, inelaborate ko lang in my own words.

Diesel engine at same size produces more hp and of course torque kaya mo ramdam ang torque is that of the diesel having higher hp can pull up a load faster on a smaller gear ratio.

Imho ang limitation ng diesel vis a vis gas engine is the rpm. Kasi diesel engine are compression ignition while gasoline is spark ignition. Kaya mas mataas rpm range ng gaso sa diesel dahil sa flwxibility nito in controlling intake exhaust and spark timing.

I have to watch the throttle pedal also when i take out the mustang. Cant just floor it anytime. Have to make sure the wheels have traction or i will spin into a wall or incomming traffic. The torque of these v8s is monstrous and relentless. I wonder how many people have made the mistake of flooring it from a standstill and losing control of the car. Hence im gravitating to AWD safer and friendlier for power and torque ratings such as these.

staggered wheel&tires?
295/305s na yun mustang mo sir?

Still stock 255 width. I need to go to 305 in the rear but ang mahal talaga.

Maybe when my facelifted version arrives will change to staggered wheels.

hi everybody!

what's needed to consider between hp & torque when it comes to hilly highway? coz i'm planning to purchase a sedan with the following specs and i would like to know if this can easily conquer those rolling hill highway even if it is loaded with 5 passengers.

1.8L Petrol, 4 cylinder, in-line, 16 valve Double Over-Head Cam (DOHC) with Dual Variable Valve Timing-intelligent (VVT-i).

Maximum power – 103kW at 6400rpm
Maximum torque – 173Nm at 4000rpm
Drive type *– Front wheel drive.
Fuel tank capacity - 55L. 91 octane recommended.

thanks in advance!

You'll be fine with amount of output from a 4-banger engine. Some sedans can do well even with less output.

Those output figures are much like the Civic FD/FB/FC with the 1.8L engine which is decent for a compact sedan. Since it is a VVTi engine, I am assuming it may be a previous generation Altis with the 1.8L engine.
