Proper maintenance
boring
Yes, you can increase it with tune-ups and by upgrading the engine.
Yes, tuning a car does increase its performance. By buying parts and tuning a car up, the performance goes up as well. If a person would tune up the engine it would possibly increase the car's horsepower thus increasing its performance.
A race car driver can keep the same engine but increase the acceleration of the car by making the holes bigger in the carburetor template. This part is also called a restrictor plate because if it has smaller holes, the car cannot go as fast as with larger holes.
Headers go on either side of you'r engine. They are the first part of you'r car's exhaust system. It can increase horse power, make deeper sounds, increase speed, and let's more clean air into you'r engine.
My car has lots of torque in first gear.
yes you can put it when u want to increase the speed of your car
200,000 miles if maintenance is performed regularly and the car is not abused.
(no it uses the energy from the car battery not the energy made by the engine)Yes it does increase consumption because the battery has to be recharged by the power of the engine driving the alternator or the dynamo
There are three main areas you should focus on and decide how much you want to do.The intake and exhaust of a car are the easiest components to change and/or improve. They are also the cheapest, but you should expect no more than a 10% increase in power.The mechanical engine parts are where you can get real power. A turbo will get you the biggest power gain, but will reduce engine life and you will have to adapt your cooling system to cope with the high temperatures. Your car's engine management system will have to be remapped and it'll have to go onto a dyno for further tuning. A turbo could give you a power increase of 20%-50%.The electronics in your car (assuming it has fuel injection) can be altered by putting in a "chip". This will remap your engine management system (as above), but your car will also have to go onto a dyno to be tuned. I'm not sure of the power gains.
Due to the increase in the compression ratio of a diesel which fires on compression rather than spark, the engine is built much stronger than a petrol engine. It therefore just costs more to manufacture.
it can start but it won't go far as the engine will "explode" because of the increase of temperature. A thermostat regulates the temperature system of your car.. Usually the engine will run too cold with out a thermostat. That will hurt the efficiency of the engine.
