The faster their car is, then better. In this fast paced world we live in today wherein just about anything can be done in seconds, a fast car would be appropriate. But, how do you get more out of your 3800? Supercharge it and you will see the difference. A good supercharger would dramatically enhance the performance of your aspirated 3800.
If you're looking for serious performance enhancement for your vehicle and more speed and power out of your 3800 then the way to go is get yourself a powerful supercharger kit. A supercharger kit includes all the important parts that you would need in order to give your 3800 a complete supercharger conversion; and you can do it all in just one weekend with the proper kit.
Basically, a supercharger kit would contain the parts that you would use for the 3800. You get a pair of engine heads, fuel injectors and fuel rails because you need to have fuel injection system installed before supercharging (however some newer aspirated cars would need fuel injector adaptors), a pair of 3.8" pulleys, lower intake manifold, valve covers, MAP sensor, coil bracket and of course supercharger and a throttle body. The supercharger kit would also include all the bolts, vacuum lines and other parts and accessories that you would need to put it all together in your very own garage. However, some kits would not come with gaskets and bolts and some other smaller accessories. These kits are recommended only for those with the proper experience and knowledge because they can source these parts correctly. But if you are not an experienced builder and you do not have access to these smaller parts and accessories fret not, because you can also purchase an installation kit complete with all the smaller parts that you need to give your car a supercharger conversion in a few days. These installation kits include the supercharger gasket, a pair of head gaskets, fuel injector O-rings among others. Also, you would need to purchase a belt available in any parts store. The proper size is 6 rib 68" belt.
If you plan to enter your 3800 in a race circuit or street racing then it is best to supercharge it first. If you have the proper knowledge in installing these parts and you know your way around the block then you can purchase your own supercharger kit and you can install it yourself in just a few days. If however, you do not have the knowledge and skills for this, then it is best to buy the parts either one by one or by kit and have someone install it for you. But be warned, supercharging is not cheap. It could set you back around £2500 to £4000 depending on who will install it and how you would acquire the parts. But the resulting performance could be well worth all the time, money and effort put into the project.
