Professional superchargers can be bought from $1500 to $7500. Professional installation of a turbocharger will cost from $1,00 up to $4000.
3. Intercooler
If you’ve fitted a turbo/supercharger Don’t visit the auto painting facility in the near future to declare it a day. Your super powerful sleeper car may need an intercooler upgrade in order to cut down on the heat of the air that is compressed from the charger. The cooling of the engine is an essential component of engine control. It improves its efficacy and last longer. Unfortunately, your turbo/supercharger compresses the air which causes it to heat up.
This is where the intercooler’s role comes into play. Intercoolers improve the combustion process and increases the power of your engine. According to thermodynamics, the higher the difference in temperature between the combustion chamber and the air combustion chamber, the greater the amount of energy generated through combustion. The cooling of the intake air results in a greater temperature difference between the temperatures generated by the combustion process and those in the air. Intercoolers are also able to cool the combustion cylinder. According to repairpal.com, the installation of an upgrade to the intercooler will run between $901 and $955.
4. ECU Tuning
The shops, or cars, are conservatively tuned for efficiency instead of speed. That means there’s untapped potential within your car. The tuning of a car that you have already installed could boost its power by as much as 20 horsepower. There’s even greater gains with tuning your super-powered sleeper vehicle and its top-performing components. The possibilities are even higher improvements if you install an engine. ECU tuning will increase your high-end horsepower and low-end torque and overall performance.
ECU tuning allows you in order to get rid of the rev limiter , allowing you to increase the rev limit beyond what’s on your dashboard. This could affect your car’s performance as high revs could cause damage to the pistons, engine as well as the transmission. It’s better to take off the top speed limiter, and then update the map of torque for your engine. It is also possible to improve throttle response and adjust the air/fuel ratio.
