Porsche never revisited the concept. Few automakers have. The principle behind a sequential turbocharging system is fairly basic. A large turbo may provide the desired peak power, but it takes a ...

to best match an engine's intended usage can result in somewhat of a compromised outcome. An engine, after all, is typically operated at a wide range of speeds - and the behaviour of the ...

Another method of twin-turbocharging is a sequential-turbo arrangement, where one turbo is operational solely at low RPM, and one is operational solely at high RPM. This almost entirely eliminates ...

Later, 'series-sequential' systems would follow - in which the first turbocharger would be shut down once enough exhaust gas was being produced to drive the second turbocharger at full power.

Enthusiasts should be familiar with sequential turbocharger systems, in which a compact turbocharger operates at smaller throttle openings and builds initial boost before "handing off" to a larger ...

The brand's innovation extends to being the first to produce a turbocharged car and sequential turbocharging in a road vehicle. Porsche has also introduced groundbreaking features like rear-axle ...

faster-spooling sequential turbos, electric turbos, supercharger/turbo combos, and mild hybridization. Two fresh ideas recently caught my attention. The Torotrak V-Charge variable-drive blower can ...

On the turbocharging side, TwinPower Turbo currently stands for a single mono- or twin-scroll turbo, a parallel setup (two similarly sized snails), and sequential turbos (differently sized snails).

What better way to do than through racing? No area of development would be off limits: an all new all-wheel drive system, sequential turbocharging, kevlar body construction. You name it.
