Keeping in mind that most road-going cars are built to be as economic and reliable as possible, performing any of these following upgrades can subsequently change how the car behaves and feels. Be sure to document yourself thoroughly before investing time and money into anything.
1. Intake and Exhaust
On a stock motor, overall results from a CAI (cold-air-intake) and catbacks (performance exhaust systems) are more “show” than “go”. That said, engine/exhaust noise is more noticeable and a minimal increase in horsepower (if done correctly) is also possible. A cleaner-looking engine bay and a chromed dual-exhaust is always a good start, too.
2. Reprogrammed ECU (Electronic Control Unit)
To avoid flashing “check engine” lights and mechanical maladies (such as a rough engine start/idle) a performance-tuned ECU is highly encouraged, as it will better “understand” any significant changes in horsepower/torque data. In automatic transmissions, an ECU can also be used to modify gear ratios (so the transmission will shift faster).
3. Turbocharger/Supercharger upgrades
Turbo and supercharger kits are often extremely expensive, but they can equally provide the oomph that you want (with the rule of thumb being that you ensure your engine can safely withstand such major upgrades.) If mechanically-savvy, do-it-yourself kits can save you hundreds of dollars in installation costs, otherwise, it’s best to have a professional do it for you.
4. Transmission
Standard drivers can get “short-shift” kits which reduce the time between changing gears, and can increase acceleration. Performance clutch upgrades can also help the transmission cope better with higher engine torque/horsepower.
5. Rims/Tires
A good set of rims and tires can be more than just attractive swag, as they can make all the difference in your car’s overall responsiveness. Though stock rims are more resistant to corrosion and wear, some aftermarket rims are lighter and wider, accommodating more rubber and increasing overall grip on the road.
I find it interesting when you said that a possible way to tune cars with automatic transmissions is to get an ECU so that they can shift faster. In addition to that, before having it installed in a car, a driver must buy it from a trusted local dealer. Doing this will help increase the engine’s lifespan and improve its performance at the same time.
Wow! I find it awesome that you suggested getting short-shift kits in order to reduce the time between changing gears. Reading through your article will help me get my car in better shape so that I can join in a drifting tournament next week. Since I need to get this auto part to improve the car’s speed, any tips on which shop should I get it from? Thanks!
