less turbo lag and more horsepower

A twin turbo configuration means that two turbos are sequentially being used. The first turbo spools at a certain RPM/exhaust flow/engine load rate (for example at 2500 rpm under heavy load) and the second turbo spools at a higher RPM/exhaust flow/engine load rate (for example at 4400 rpm under heavy load). Usually the two turbos are small enough that the first turbo will spool fairly quickly to a usable boost level (if not full boost), making low RPM drivability good. The downside is that the full powerband is not as smooth as a single-turbo installation because there will always be a "blip" or interruption in the power when the second turbo becomes spooled.
Additionally, a single-turbo installation, of one large turbo, can often be more a powerful setup than a twin-turbo installation. The reason is that the single turbo allows a single large turbo to operate at its maximum boost potential producing usually more power than 2 small non-optimized turbos. For example, in the Toyota Supra Turbo, which is twin-turbo stock, drivers who wanted power in the 500-600 horsepower range would replace the 2 small stock turbos with one large turbo. Of course this requires custom dynotuning for a smooth powerband.

"twin" means that it uses two turbochargers ......... Same turbocharging process just two chargers doing the work.
Usually twin turbo cars have an intercooler to keep the air charge temp to a minimum...
