Lightweight things move faster than heavier things — that’s as basic as physics can get. This solution is simultaneously low-tech and work intensive, in that it involves switching out heavier parts of the car (throughout the car, not just in the engine block) with lighter parts so as to make the car lighter and more aerodynamic.
There are a lot of options: get rid of extra seats you don’t use if you don’t cart a lot of people around; replace glass windows with lighter plastic or acrylic versions; or even remove parts of thedashboard. Disc brakes even offer significant weight difference over traditional brakes
2. Performance Chips
If you drive a late-model car, it’s highly likely that there’s an onboard computer regulating things and running the show, controlling such functions as timing, anti-lock brakes and the all-important fuel-to-air ratio. Performance chips (or superchips) are “hacks” that can be installed to override factory settings, and they’re most attractive to gearheads since they can increase the power of the engine and horsepower
A performance chip sets new parameters for the functions of your choosing, such as telling your car’s engine to use gas slightly more efficiently, or to intake more air for a bigger combustion.
3. Air Filter
Aftermarket air filters allow for more airflow into the engine for a more efficient use of the air/fuel combination, while also blocking contaminants and impurities that slowly degrade performance over time. Secondary air filters are generally made up of a thin layer of cotton or other material housed between several layers of impurity-catching thin mesh. High-quality aftermarket air filters (versus the standard, paper-based ones that come straight from the factory) drop into the engine’s air box, and that’s about it for installation. And because they’re made of fabric, they’re washable, making for an inexpensive, reusable performance enhancer
