What is importance between torque and horsepower?

[lkeong88]

How come keep comparing with B16A take one b16b and see how much horsepower

haha, lets back to the topic....for me i strongly believe high torque car will always win. for example a 2000cc continental has 200nm torque from 1500rpm onwards to 6000rpm but only has 120whp, but it will smoke b16a for good. and it will cruise 200kmh around 3500rpm, wherehence a b16a will be doing very high rpm at 180kmh n canot maintain that speed more than 45 minutes coz it will heat up.

in this point of view, high torque is more important.

Hmm...it is torque at the wheels that counts,which in this case,the gears plays a role...which engine characteristic is better,depends..very hard to compare because each engine is different,gear ratios are different,no apple to apple comparison..generally,if the vehicle weight is the same,and the difference of torque and hp between two car is minimal,on acceleration 1st,2nd and 3rd gear,high HP and high RPM engine will win..high torque engine will shine on high speeds,4th to 5th gear..but dont la compare 4AG to EVO,of course Evo will all the way la..

Well~ let compare with Mivec 4G92 where produced a pretty 180hp, but Vtec only B16 was produced 170hp. In the end, 4G92 Mivec will still always lost to Vtec B16 le...

in the end, macam no conclusion liao....hahahahahha

to simply put:

torque: affects the rate your car can accelerate
hp: affects the ability for your car to maintain speed

continental car will win on top speed and long distance but not on acceleration..
b16a will reach 180 faster than continental car..
unless if you talk about alfa or fiat..it different story
if bmw, blacktop accelerate faster.(based on my previous experience)
power to weight ratio..
there are some guys at kedah..
evo vs bmw328
10km long race
evo accelerate faster
but bmw wins

mivec max torque oni in narrow powerband but b16a torque is wider powerband. 92mivec can produce 17kgm torque compare to b16a 16kgm torque. mivec can produce 17kgm torque but oni at narrow powerband, b16a produce 16kgm torque at wider powerband . tats why vtec can all the way tarik from 5500 rpm to 8500rpm wen vtec on. mivec 6000rpm hp is less than b16a 6000 rpm but oni win b16a at 7500rpm. the max torque is too narrow for mivec.

so dun wan compare hp, but compare power band.

another example, rb26 come wif sequential twin turbo coz wan to have wider powerband. wen ppl mod to single large turbo, the powerband narrow but max torque produce at peak of rpm. this can achieve higher hp but low rpm sure less power.

1 IS 4WD 1 IS 2WD. 4wd can easy use all hp wen pickup from zero but oso the most suffer powerloss in tranmission.

hmmm its been a while since i logged in here..

back on topic, a high revving engine like a B16 doesnt have the 'pull' at low rpm, in contrast to a high torque engine at low rpm.
suffice to say, a AGE could cruise high speed easily if compared directly to a B16.
i mention these 2 engines coz its the perfect example..

 

[Dayline668]

There is no replacement for displacement.

 

[nurburing]

okla, i quite agree with the powerband thingie. in stock form b16a eg6 is quite a powerful car due to power to weight ratio, and its abilty to rev to 9000rpm undisputably its 1,2 gears are very fast making 0-100kmh. a stock 1600cc mivec can never catch up.

but what if, both heads up for a touge uphill race ? the person who drives b16a have to be super-fast in making gear change and maintain highrev, while the mivec driver just stick to 2nd gear and focus all his attention to handling control.

now see the picture ? plus if a 1600cc mivec throws in stndalone ecu n highcam, providing a good powerband from 3000rpm - 8000rpm do u think it cant win b16a ? mitsu engine are wellknown for WRC, honda were only in formula1.

and we mostly driving with torque NOT hp. coz we cannot hit hp(peak power) all the time and this is where torque is the most crucial

so imho, torque is more important than hp. but in laymen terms, regular ppl does amazed by small engine making BIG hp and say "AWESOME".....hehe

 

[khoo198]

guys....the topic started at Toyota thread....so pls discuss abt hows toyota's torque and horsepower only...ok?

 

[nurburing]

sorry, but the topic dint mention toyota although its a toyota thread....

anyway, carry on :)

 

[muzhaffar]

b16 maybe faster at straight line..
but at circuit or cornering road,..
20v has advantage

Yeah~ Because all of big boss here are trying to show much clear view in torque and hp, so need to involve some non-toyota (sorry).

Since some one here was said, HP for straight line; torque for cornering road & hill touge.
So you means 20V have more torque than B16?
But I think, Honda have much better suspension design than ours. How you think?

yup
better suspension..
but how about in terms of reliability?
vtec open at high rpm..
20v vvt activate at 4k rpm..
for me, more advantage at cornering..
no need to take cornering at high rpm to maintain the power band..
just my opinion..
if wrong, dont shoot me..
and some more, dont rely on the factory output power..
it not really2 accurate..

the torque produce by the electric motor is the best
high stall torque
very fast 0-100 time..

 

[nurburing]

yes ofcoz, that is why i say b16a is powerful, but not the most powerful.....sr16vvl N1 is more powerful than b16a, but then if vs a 4age 20v on a hillclimb, maybe even sr16vvl N1 might lose to 4age....WHY ?

hehehe

 

[GasPedal]

Erkkk :hmmmm:
Why I use 4AGZE but with C56 gearbox + bigger crank pulley, I can always win B16A (near stock) and B16B (near stock) too? 1 thing I realize is when drag race between this 2, I found out in 1st 50-100m i can lead it easily; But once at 300-400m, I found B16 is closing up already.

oo~ No wonder I feel more comfortable when uphill compare to B16 la...

U said u use bigger crank pully, is that suppose to spin the supercharger faster? This will increase boost, torque n horsepower, i dont think yr 4agze is near stock condition (just mod air filter n exhaust), thats why u always win.

My friend told me he saw wira with 2.0 4g63 dohc na play drag with ae101 with 1.6 4age 20v blktp with just airfilter n exhaust mod, they play 3 time, 20v win from 2nd gear onwards all 3 time.

Could somebody confirm this, or maybe the wira driver miss shift or something....

 

[muzhaffar]

i play with satria turbo before..
dont know what engine..
but can hear the bov sound..
at that time already 100++ km/h..
then he accelerating and i catch him from behind
drop to 4th gear and accelerate
manage to tailgate the car until 180 km/h and my speed cut does it job..
stock blacktop 6 speed...
even air cleaner stock..
with ae101 double muffler..

 

[lkeong88]

If not mistaken 4g63 NA no mivec, horsepower only around 140hp rite? Its just something like camry's engine ? 3sfe?
