What can increase acceleration?

[flashbang]

Easiest way to increase acceleration is to buy a new car. If you bought a slow car, don't expect it to fly like a F1 racecar...

Just to add...

 

If want to play, buy a car that can play.

 

If want to play but want to go cheap, you will play forever but will still not be satisfied

idk why, on dyno my car shows 333nm of torque from 2200rpm all the way to 4000rpm. on paper the acceleration is 8s. but when i do real world test i get slower timing?

 

gear ratio problem?

That's around 260 to 280 bhp ; on a normal saloon car you should be going under 6 sec .  Is it a heavy SUV since you are getting 8 sec ?

333Nm is on crank. wheels ard 250+  mine is the all new C180 with monster tuned. now doing 201bhp

Your torque of 333Nm is available from 2200 to 4000 rpm .  At 4,000 rpm , your power output is already 186 bhp . If you are having 201 bhp max , it means that your max power occurs relative close to 4,000 rpm , my estimation probably around 4,200 rpm .  Beyond 4,200 rpm , your torque drops dramatically .That's why you are getting 8 sec , the engine simply runs out of steam beyond 4,200 . Because century sprints are done with WOT , you need peak power output preferably all the way to 6000 rpm and beyond .

 

C180 is 1.6L .   A 1.6L NA engine gives you around 120 bhp , and in your C180 with turbocharging , you get 150 bhp stock . And because you are squeezing another massive 50bhp out of it to make it 200 bhp , the engine becomes grossly inefficient at the higher rpms hence the massive drop in torque at the higher revs.

i look at my torque graphs. the 333nm comes in at 2200pm and stretches flat out till 4000pm b4 it starts to drop.

 

so its better if i use pedal shift and change gear at 4k?

[F355]

Shifting at 4k will not give you a lower sprint time ; but it will give you the feeling of a very torquey drive .

so ur advice to get a better sprint time. when do i shift my gears?

[Mkl22]

At the redline of course

[Terri]

If you have lauch control then you need to use launch control to achieve that figure.

Otherwise if just stepping from idling RPM from stationary you will not hit it.

Temperature, tyres, driver, weight, fuel, all affects.

Mfg data is controlled data performed at controlled environment.

real life... will never get close.. 
But as long your car out accelerate others means your car better than theirs already.

It's not pedal shift.

All automatic cars are smart enough to shift gears depending on your acceleration / speed condition.

 

If you stepped lightly on the gas pedal, it's going to shift gears at 2000 rpm generally.

If you stepped harder during acceleration, the gears will shift later, probably say 3500 rpm.

Well,, if you then stepped pretty hard, lets say 90% to 100% to the metal, then it will shift at say 5500 rpm.

 

To use pedal shifters, might as well just step harder.

 

In my car, if I use the +/- gears, the shifting becomes more harsh, can feel the engine / gbox will feel a bit fierce during gear shifting.

 

If I just step fully, the gears shifts smoothly, even at 5500 rpm

 

Just use leg.

That's what automatics are for.

 

Forget about pedal shifters. They are for posers.

Don't stress out your engine man, does your car come with drive settings i.e sports mode, comfort mode etc?

Optimum timing of gear shifting, proper inflated tires and turn off your air con (air con take up some HP from the car) will increase your car acceleration. Checkout how its works at http://www.carreviewsncare.com/my-ride/

surprised no one mention lose weight... aka driver + passenger :P *tongue in cheek*

[Stanfordho96]

yeah it does. twitch the gear shifts and more sensitive gas pedal(like a sprint booster)

 

I went to tune the car again. its now about 350nm.

 

the wheels spin when i do a sudden flooring of the pedals.

[Mercury1]

I see, given the case if you switch to sports it should change at optimal no need to use the pedals. Normally I use the pedals in comfort mode when the gear lags on the previous one too long while driving.

 

Whats the width of your rear tyres? My car puts out about 350nm but has a 275 rear tyre profile which matches the output so no lose of traction.

If you do any modification it won't always improve the acceleration, but what you really need is more horse power or less weight. A different transmission system might increase acceleration but it is expensive. The cheap and best way to improve acceleration is by removing unnecessary components and reducing the overall weight. Getting an oil change, getting higher quality oil, or even checking the spark plugs might improve your car's performance. https://www.yourmechanic.com/cars/hyundai
