10 Tips to Increase Engine Performance
These tips are of a general nature and not specific to Mazda. The article is actually specific to carburetors, however, the same basic rules apply, that's why I changed a few---to reflect on modern efi.
FROM: 10 Fast-Quick Ways to Increase Engine Performance
1) Synthetic lubricants reduce friction, which can do two things to your engine: increase power and reduce friction. Typically a couple horsepower can be achieved.
2) The ignition includes everything from the coil to the spark plugs, and sometimes a simple replacement of the plugs can help your engine to run smoother. An aftermarket ignition system can help increase performance because of a higher energy that comes with aftermarket systems. It also helps to check ignition timing, one of the biggest performance robbers. Ever hear a ping or knock when you press the gas? That comes from your ignition, and making sure your timing is can eliminate the extra noise, of course using a better grade of fuel will help, too.
If you have your ignition coils on top of your spark plugs, go to aftermarket for more spark! My stock ones where 20,000 volts and my aftermarket ones are 40,000 volts. Try MSD Ignition or Accel.
3) increase throttle body and injectors. More air in, requires more fuel, and that means more air out… which can give you a slight gain in power. Go too big, however, and you might see your performance and economy suffer. I actually removed part of the butterfly shaft to bring in more air, pic below!
4) Increasing compression. The compression increase gives the potential for a better burn inside the combustion chamber. This is not easy.
5) roller rockers can reduce the friction that a standard cam and rockers produce.
6) Aftermarket intake like K&N to let more air in. Colder air is more performance.
7) Increasing the fuel hose. Increasing fuel hose size on a performance engine will help the fuel flow a little better, with less restriction.
8) a better flowing intake manifold can help. Porting!
9) Exhaust system: headers and porting!. If not changing headers a good re-design may help. As a general rule, you can enlarge the pipe diameter of your OEM exhaust system by 1/4 to 1/2-inch to increase your horsepower. However, any additional increase in pipe diameter is likely to decrease your performance; specifically, low end torque: FROM Magnaflow: MagnaFlow Performance Exhaust - FAQ, Frequently Asked Questions This would include increasing the size of your rear main cat that doesn't have O2 sensors around it!
A good example, click on: https://www.mazdaforum.com/forum/maz...-design-28940/ Lots pics in that thread, 2 pics before and after also below.
10) Power programmer. If one is available for your car. Companies: Hypertech, SCT, Diablosport. For some specific to Mazda 6: Twisted Visionz - Online Store
