What are turbochargers and superchargers—and which one is better? The amount of power an internal-combustion engine can produce depends primarily on how much fuel it can burn and how quickly and efficiently it converts that heat to mechanical force. But fuel requires air the oxygen contained in air, actually to combust, so an engine's maximum output depends largely on how much air it can take in to burn that fuel.
Hence the concept of forcing-feeding an engine more air than it would normally ingest, so that it can burn more fuel and produce more power. This additional intake air can be supplied by either a turbocharger or a supercharger. Both are air compressors, but they operate and perform very differently. A turbocharger uses the velocity and heat energy of the searingly hot and expanding exhaust gases rushing out of an engine's cylinders to spin a turbine that drives a small compressor, or impeller, that in turn stuffs more air back into the engine.
A supercharger also pumps additional air into the engine, but it is instead driven mechanically by the engine via a belt that runs off the crankshaft or by an electric motor. Each of these power-boosting technologies has advantages and disadvantages, but the most obvious difference from behind the wheel is a slight delay in response to your right foot in a turbocharged car, especially when you push deep into the throttle.
By contrast, a supercharger has no lag; because its air pump is linked directly to the engine's crankshaft, it's always spinning and instantly responsive. The power boost it provides, and therefore the engine response you feel through the seat of your pants, increases immediately in direct proportion to how far you press the accelerator.
While the turbo's primary drawback is boost lag, the supercharger's is efficiency. Tuning your car is expensive and for doing it only to optimize a cold air intake is not worth the money. A cold air intake is a cheap and easy upgrade that does not require tuning. Common problems include a decrease in gas mileage, hesitation when shifting gears, slugging acceleration and even a dirtier air filter. Begin typing your search term above and press enter to search.

How do I make my automatic transmission handle more power? Can you put a twin turbo in an automatic? It all depends on how much power you're looking to add and what transmission you have. If you had like a turbo or , you could buy a simple shift kit to help deal with the power.
Most automatics are designed to slip when they shift, which makes for a nice smooth ride but increases wear on the tranny, and the shift kit makes them a bit firmer. There are companies that will build up a transmission for you depending on what your needs are. Sometimes a stock transmission can handle big increases in power without any tweaking at all.
The transmission in my car is a 4T65E-HD, it's a slightly beefed up version of the 4T65E that gets mated with standard 's and other engines around the same power. But I've heard of people getting more power out of their NA and having no problems with the tranny.
The HD version goes with higher power stuff like the SC and LS4, and again I've heard stories of upping things a bit and still having zero problems with the stock tranny. As owner of both an automatic and a manual no bias i can vouch for that, all the quick cars are autos. A botched gearchange with 1, horsepower would be a very expensive disaster. Ask around, take it to a transmission shop and have it built up a bit and a stall put in, and you'll be fine with any power increase.
You can generally strengthen an automatic transmission to handle big torque. No different to a manual, where the stock clutch and gears will only handle so much. On a car with suitably big power, an auto car is consistently quicker than a manual one.
If you're making enough power, the lack of direct mechanical connection between the engine and driveshafts is not relevant. Its only in a really underpowered car, where you'd want to launch with more RPM than a stock auto permits, and the parasitic loss from a viscous coupling is actually noticable, that manuals are quicker.
