How much Torque is needed?

[Rickster]

Anything that is above 170Nm (must come in mid range RPM) will be nice....provided that your car does not weight 1.5ton.

 

How about a mid-range torque of only 137Nm, but the car weighs only 1 ton?

[Rickster]

Thats why many conti cars, despite very low ratings BHP/ton, does not feel sluggish as conti cars tend to focus on bringing out more torque.

[Akula]

Considered a little high.

Read through the thread. There is another problem with asking for a magic figure... Torque figures at the wheel (unlike power) is affected by the gear ratio as well, so two identical cars with equal engine torque with diff gear ratios will show different torque figures at the wheel, at each point along their curves.

If it develops 80% of it early in the rev band....then not so bad.

 

But dun expect too peppy performance.

[Ghostrider]

Not that conti cars bring out more torque...its more on their gearbox ECU unlike Jap and Korean which IMHO is a lazy unit....dun downshift when required.

 

Jap boxes when you lift off the pedal at 90kmh...it will remain in top gear until you stop then it goes into 1st gear. So when say halfway thru and the lights turn green and you need to move, you step on the gas and it will respond slowly....then you step a bit harder it downshift 1 or 2 gears.

 

Conti on the other hand will downshift according to the speed....so when you step on the gas at anytime, it will be in the proper gear to move off smartly.

[Wt_know]

that's why people mod their car with 'sprint booster' and something like that to improve the throttle response. however, all these i suspect is butt feel only and the unit does not work or response well to varities of car

[Dwoon]

Wah.... lidat the FC sure kena big time.

 

But Jap gearboxes also provide a responsive gear switch... but need to actvate that option throu' a switch mah... then the FC suffers like crazy.

Often read comments that a NA car lacks the torque. Also read that a TC-ed car can overtake effortlessly, faster response in changing lane. So how much torque do you think is required for a NA car to do the same?

 

Lets say how much torque do you think a stock 2L car should at least have? 20?

 

Regards,

 

NA cars should have 999Nm to push the car fast. 1000Nm will burst your tyres.

[Saabretooth]

"double vtec".

new phrase?

 

anyway,even vtec can't produce that much torque compare to turbo assuming same power and capacity.

 

hehe.... some morning creativity just kicked in. ;)

 

Thats true. unless its a detuned TC car if there is such a thing.

This question is just simply too general.

 

Unless you are able to define your purpose for asking such a question and narrow down the factors, otherwise there are just way too many variables to even consider.

Correct me if I am wrong, but it seem to me that you have never sat or driven in a TC-ed car?

I think a ride in a friend's TC car will give you all the answer you need.....

 

how much torque a TC-ed car have to be able to overtake effortlessly is the same torque your NA car needs (if all other factors considered). Period

not only that, some of the conti paper specs are done differently from Japs/Koreans, eg, the 1 to 96km/h is done with a specific passenger weight on the passenger seat, 1/2 petrol tank & also a specific luggage weight in the boot

[Marcng]

my car is a 2L car weights 1.4 tonnes and has only 375mn torque@ard 3.8k rpm

is easy to overtake cars at expressway but the G pull isn't very strong

[Ghostrider]

That is e-throttle then you need sprint booster. It is there to "fool" the electronic throttle...layman term...a lot of drivers on e-throttle cannot gradually step the throttle and they step a bit....no action (cos the e-throttle opening) then they buay tahan....step a bit more....then throttle by then would have open up. Its like a retarded action.

 

E-throttle does nothing to gain power or torque. Its just there so that pple feel shiok....step a bit only the car go.

[Ghostrider]

You mean the sports toggle ? That would usually switch your ECU into another mapping altogether....older cars will just hold the rev but newer cars will have another map for "sports" mode.

 

Yes....FC will go up. Power does not come without a price.

 

But conti dun even need to switch to "sports"....and they are responsive liao. They are more advance than Japs....my ex ride a 16yr old Bimmer already has 5 speed gearbox....today Jap boxes still have 4 speeder....hianz...

maybe he often get overtaken by turbo cars.

so he is asking for ways to enhance his 2litre NA car to match turbo cars?

This could be another topic on its own. This is more like a myth or hearsay. No one can be exactly sure about this as there is no concrete evidence.
