Instant takeoff from standstill. The reason is so much more increased torque from the Surbo, that there is no need for the gearbox to allow slip to prevent engine stalling. So, there is no more waiting for the vehicle to accelerate.
Fewer flat spots, due to light accelerator pressure, and therefore no over-fueling, that can affect combustion.
Higher rpm, because of the greater air density from the Surbo going into the engine. In other words, there is higher air compression. The result is faster acceleration, with the engine routinely reaching 4500 rpm to 6000 rpm with just half pressure on the accelerator, and in D mode! The max rpm depends on the gearbox program.
Easy gear kick down with just a light tap on the accelerator, because the Surbo's higher density air is on standby. More air is necessary when a lower gear comes, with its higher engine rpm. To illustrate, at 80 kph in 4th gear, press a bit more on the accelerator and see 3rd gear selected, and if you want 2nd gear albeit at 5000 rpm, just repeat. To change up, just release the accelerator a little.
Higher top speed, because the accelerator never needs to be floored, so that air suction is never depleted and acceleration can continue in each gear. This also means more momentum for easy cruising and hill climbing.
Little speed is lost even when foot is completely off the accelerator, because the engine back pressure so created makes the Surbo jet and compress the air, and the vehicle body pushes the engine and force feeds it with this higher density air. This may also help you exit corners faster, since the Surbo is "on" through a corner for the above reason.
Confident overtaking, with easy gear kickdown selection, and higher rpm capability.
And you can keep driving faster than usual, because there is no fuel penalty. After all, the rpm limit comes with just half throttle!
If you have an automatic vehicle and wish to make it fly, please come and try the Surbo.
