idle rpm means the engine rpm when the car is stopping (like stopping in front of traffic light) ? if i am nor wrong , it tends to show 1000 rpm most of the time . Is it normal?

my iswara se comes with 4 speaker . But only 2 speakers are working .(the rear speaker) , i ckecked it , it's clarion brand. Is it good ? I personally dont like it very much and feel that blaupunkt on the 1996 model sound better  .Is it on the ori condition? i mean is the original iswara 2003 se model comes with 4 speakers? I also noticed 4 tweeters , but no sound come from the tweeters. What's the function of the tweeters? How to make the tweeters work ? btw i have pioneer head unit.

what is fader?

We welcome all GaGa Iswaga owners regardless. I just wish to inform you sometimes the otai here is very technical. When they explain, will have tons of crazy flying fish, prawn, crab here & there. If you can't understand, just wait patiently and ask the question politely, many will answer you with true passion geh

say what? mai yau hai fake lancer fiore Plotong? so there's lots of teknikal term being used for diskasen. sarj as "kon9lan7fem", "dnmgh", "ammoshaft hits the fan"

For my case, the sound developed immediately after I replaced the exhaust muffler & piping due to corrosion holes. So I thought the sound was from the exhaust system brackets, but I shook the thing hoping to get sound, but it was quiet.

Torque is leverage, measured in Newton-metre, pound-foot etc. For example, when you tighten the
bolt using spanner, torque that you applied is your applied force x the spanner length. It is independent of speed.

Horsepower is another name for power which is energy expenditure per unit time. measured in
joules per sec i.e. Watts

The above 2 concepts are related.
Torque x rotational speed  = power (kW) or horsepower (hp)
(one horsepower  = 0.746 kW)

So in the spanner example above, power depends on how fast you turn the spanner, even if the torque remains the same.

Yes torque determines how much you can accelerate the car, and so is horsepower which not only
accelerates but at what speed at that time. They are not really independent stuff, just what
kind of measurements are involved. Horsepower depends on torque AND speed at any one time.

TECHNICAL STUFF:

Torque of 4G13 engine is 109 Nm @ 4000 rpm (measured at crankshaft).
1st gear ratio = 3.363, final drive gear ratio = 4.322
The gearbox thus reduces the 4000 rpm to 275 rpm while increasing torque to 1584 Nm.

Radius of tire 175/70R13 = 0.288m,
Since torque = force x radius arm, you can calculate the pushing force to be
1584 / 0.288 = 5509 N which is equivalent to 561 kg force.
This means a force equivalent to 561 kg is pushing your car forward in gear 1 at 4000 rpm.

The power that generated at the engine = Torque x rotational speed
=  109 x 4000 x 2 x 3.142 /60 W = 45,664W = 45.664 kW = 61 hp approx.
This is the amount of energy extracted from burning petrol per sec and translated to engine
shaft output.

The power mentioned here is the same thing as in your household appliance like 2000W kettle,
50W lamp etc.

Torque can be increased or decreased by way of the gearbox. Power remains nearly same, i.e.
reduced slightly by frictional losses passing throught the drive chain.

At gear 1 & 4000 rpm, the speed is 30 km/h. The road friction & wind resistance is about
17.8kg, so the balance from the 561-17.8 = 543.2 kilos of force suppled at the wheel is to
accelerate the car.

Thank you guys for the wonderful Kar Huash TT!

My pleasure to meet up with jondankawan, despite years of Savvy ownership, in the end meet up as Iswara owner

Both cars are very good. For, reliability, I chose Iswara over Savvy. Only chosen people can bear with Savvy, not me.  Respect to all Savvy owners and Saga Iswara owners also (david boleh double respect la      hahaha)

after driving the 12 year old iswara for a few days , i noticed that the engine started to develop a strange sound . when i accelerate , the car takes along time to rev up compared to my uncle 's 1996 iswara. i heard  the 'zik , zik , zik' sound . i think it's the engine 's problem .Is it expensive to fix this?

i wanna save fuel , so I change the gear even the car havent reach the 2.5rpm . so i often use gear -5 altought the car speed is only 60km/h. The engine is not dead and the car is not vibrating too much. But , i noticed the sound of 'zik, zik, zik ' , seems like a bearing sound. I'm wondering will it cause harm to the engine?if i change the gear so quickly ?

Lol. @ thought drive at lower rpm coyld save the fuel. Will it cause harm to the engineif I use low rpm (not enough speed) to drive the car?

why need to pull out the fuse? what's the prupose of the fuse? if no fuse , the light can light up? p/s : i havent try pulling out the fuse. 

Thanks for the tip! Then I assume that if I have enough money, full overhaul will be my first choice in servicing the car? How much will it cost roughly?

And I am thinking of doing maybe transmission fluid flush or brake fluid flush while I earn more cash for the overhaul, are they recommended?

Thanks!

how do u learn how the car system works?  where do you learn it ?

My car is a manual. The shifting has never been smooth since I started driving it, so felt like want to do some flushing if it helps. Shifting only smooth sometimes after the engine has been running for a while.

Btw, regarding on Davidke20's comment on shifting at 2.5k RPM and above, would it does more harm to my old engine's pistons as it always spins at high RPM? I normally drive 60km/h (hahaha my hometown people all drive slow slow, so so do I ) so it will be at 4th gear at 2k RPM constantly, realised that I stepped less on the pedal at 4th gear as compared to at 5th gear, but just scare at constantly 2k RPM will like, does harm to my old engine

2k RPM will like, does harm to my old engine

I  pumped my car with petron 97 petrol yesterday . I can feel the difference. The car experience less engine vibration  and less engine noise. 

Ayam a regular petrong user, and belib their ron97 is the worst in the market normal engine sound indeed reduced, but will create knocks when engine on load funny shit, dunno what kinda soap water added

engine timing? increase it ? or reduce it??
