niceputera,
thanks for helping n sharing those above,i need to ask for your personal exp for stuff's done such as below:-
1)How was the diff after p n p?...was it more of pick up or higher top-speeds?
2)Was the torque higher bcos of h/comp/pistons?ans is it satria 1.6 pistons or mivec's?
3)J5 chip...performance chip?or?
4)Was there a diff felt on gas pedal with fixing of a r/regulator?
Sorry,but just so curious on these as above...thnx for the help again.
Satria81,
1)p&P - You'll gain both if the correct technique being applied. But if u over polished it by more than 1mm ( non experience mechanic always do this) youl'll gain top speed but you'll lose pick up at all.
2)The torque was high because all the components work together. There is no such thing as 1 specific component can boost torque. The pistons were satria 1.6 pistons. Mivec pistons will give u CR of 12.0:1 and eventhough it will be good for a bit more overall power, you'll have to be more conservative with you timing since it will prone more to knocking.
3)J5 - is the programmable chip by Matspeed that can control / change the air fuel ratio and the ignition timing of the engine.
4)I use the f/regulator to compensate a little for the shortage supply of the existing / std injector. If u reach this level, there is no more thoughts of " can adjust / play around with f/r for better pick up etc etc" - that phrase is limited only to those that do not serious to build up their engine.
Satria81, If u really serious to build an engine - any engine - than you must plan on how to go about. U must alway remember, an engine will only yeild good power if all the components can work together in harmony. Harmony is the key word.
I give u an example. U build ur intake, head, internal components but u still use std exhaust piping. Where can all of the power that is being produced in the engine transferred to? Yes it will go through the std exhaust but the std piping is only meant for std exhaust. With a modified engine, the total gas volume and velocity is so much greater than the std engine. Because of this, the std piping cannot channel all the gas in the most efficient way thus will results in some of the gas to stuck inside the engine. What will be the cause of this? It will create back pressure in the engine. And because it is creating a back pressure, the engine cannot inhale the large amount of fresh air to the head because the existing air / petrol mixure that has been burned out cannot be channelled out from the head. And because the head cannot inhale the required fresh air, the fresh air petrol mixture that get into the combustion chamber is less than ideal. Less than ideal - it means less power & tork.
That is why u can see why people mods their engine and getting less power than std or higher power than std but much lesser than their predicted power for that exact mods being carry out. Remember the key word - harmony.
Rgds.
Note: U eat, u defecate. U eat more, you need to defecate more, right? That is the simple way to describe it.
This topic is to share how to bring out a team and type of engine preparation is needed! N if things goes well it might became true that a team 0-100 member will step up!! I should start with race type...
