The picture posted is a turbo, headers and exhaust. On the up-pipe/headers side of the turbo, there is an extra flex pipe with a black box attached to it. The pipe pulls air in from the hot side of the intercooler and then pulsates it through the black box (the rocket) and then finally through the turbo, keeping the turbo spinning. This would prove to be a more effective way at canceling out the lag and not going with the "bang-bang" ALS that a lot of cars use.
