i've got a 1998 hyundai elantra and i wanna get my money's worth out of my car. what do i need to change in order to make my car faster, and more efficient? right now, everything in my car is the same as the day it left the factory, aside from a few changed spark plugs and other basic repairs from normal wear and tear. any advice is greatly appreciated. i also need to know how to keep my 12%26quot; subs from draining the battery of my car. thanks much!How do i make my car faster and more efficient?well you could get a tune up, that could help, a free flowing exhaust system, and a cold air intake. all of those things will increase your power and efficiency. however that is about it to make it more powerful and more efficient. if you are more concerned with power you can put a turbocharger on it and as long as you keep your RPM's down, and are gentile on the gas that shouldn't affect your mpg's too much.
as for your battery, you might need a new battery if your sub-woofers are draining your battery down, and you might also need a new alternator, one that will be able to produce more electricity. also you might want to leave your car running when you are using a high output sound systemHow do i make my car faster and more efficient?Usually performance mods mean worse mileage. Cold air intakes do not add enough horsepower that you could feel the difference other than a better sound. A free flowing exhaust system would help the sound and performance a little, but you would still not notice a big performance jump. But both of those things would make it more efficient.
By upgrading to better spark plugs, spark plug wires, new fuel filter,keep the oil changed, keep your tires inflated properly, having good wheel alignment, keep the fluids changed (coolant,transmission,etc), and make sure your suspension is not damaged/worn, all those things can help give you the most out of your gas mileage. Another thing that could help is to take out the subs because they weigh alot. Any extra weight you keep in the car just adds more weight for your engine to pull, hence taking away power.
You can add a in line %26quot;Cap%26quot; or capacitor. It stores power while the amp is on and distributes it when your car gets low on voltage. This helps stop your lights dimming or you battery going low.
Good luck!How do i make my car faster and more efficient?I agree with what everyone said besides the nitrous oxide answer....hurrmmm not street legal and def not suited for this engine. Also expensive and pointless in a hyundai.
As for the draining of the battery your alternator should be able to run all the electrics on your car and charge the battery at the same time sooo either you have a problem with the alternator or the alternator is not large enough to power the subs.
I am assuming you are running the stereo with the car running otherwise you will be seeing the battery go flat more often.
I have a 12 inch sub in my 3.0L skyline and have not had problems with my alternator as a result. It's not a hardcore system - newer cars have loads more electrics than what you have with the subs combined so yeh it may be worthwhile getting the alternator checked out.How do i make my car faster and more efficient?K%26amp;N Air Filter - Or similar
Free Flowing Exhaust System - Or just a better muffler
Synthetic Oils
These are the cheap and simple first steps you can take.
Of course there is the other steps of making sure the tires are at the recommended pressures and keep the foot off the pedal so much.
If you turn off the subs then the battery is not supposed to drain. I put one of those yellow tops in my car and I can let my 12s pound for almost an hour before the battery gets too drained to start the car.How do i make my car faster and more efficient?many people will say cold air intake, exhaust system or something. But that will cost you an arm and a leg, you can buy a programmers or chips to tweak timing fuel ratio or gears. A cheap one will cost you about 300 bucks, or a used one on craigslist is cheaper. you cant get horse power with out sacrificing gas milage but with this you can go back an fourth. also get a better alternater for your batteryHow do i make my car faster and more efficient?The bad thing with making the car faster is that your going to pay more at the gas pump.How do i make my car faster and more efficient?nitris oxideHow do i make my car faster and more efficient?cold air intake will help a little
