Instant Improvement You Can Feel

The Surbo makes the throttle lighter, in addition to vastly improved engine torque. Here's how Surbo feels like, by engine type.


You'll get a faster takeoff after clutching in, a quick dash to 3000 rpm, split second Surbo charging with throttle easing, and easy revving to the rev cut with part throttle. Vibrations on the accelerator are clearly felt, due to the denser air trying to pass through a smaller throttle opening. Gearchanges are faster, because as the accelerator is released between gears, the engine back pressure causes the Surbo to charge and hold the air pressure, so that rpm does not drop so fast. The result is like doing a heel and toe, and the gear is not only more swiftly changed, there is more power after the gearchange, shown by the gain on another car also going through a gear change. The Surbo charges through a bend as accelerator is eased off, and you get a stronger exit from mid bend after accumulating charge. If your car is front-driven, there will be a side force that tightens its line, reducing understeer.

For automatics:

The takeoff may be faster than even manual cars, because no clutching-in is required! You get a headstart. No wet clutch delay due to sufficient torque to allow full clutching. The throttle feels light, and gearchanges are smooth. The stronger low end torque means a quieter and more relaxed drive. There is no need to rev, but when desired, high revs come more easily, to a minimum of 4000 rpm at part throttle even for the laziest gearboxes. At the point where gearchange occurs automatically, a further widening of the throttle may extend the revving to 5000 rpm. Some sporty gearboxes will allow full revving or at least 5000 rpm with part throttle. Releasing the throttle pressure results in a back pressure that is sustained by the Surbo, and the car rolls further with less deceleration. Kickdown is easy with just a light press on the accelerator, and a further gear down can be induced afterwards. to prepare for overtaking. For some cars, kickdown from second gear to first gear happens while doing a u turn, making acceleration afterwards faster. This is because denser air is always on standby.

CVT (continually variable transmission):

Takeoff is faster, and instead of operating at 2000 plus rpm on a high gear ratio and taking longer to accelerate (which uses up more fuel), the rpm becomes higher at 3000 plus on a lower gear ratio and less time is taken to reach cruising speed. Lower gear ratios (kickdown) are also easier to induce, with a light press. At superhighway speeds, a longer gear ratio (lower rpm) may be allowed due to added torque, and outstanding fuel economy figures are achievable.


Cars such as Mercedes and twin-charged turbo VW's have superchargers. While the supercharger promises to provide a linear charge proportional to rpm, it is by itself a load like an airconditioner, being driven by the engine's pulley, and retards acceleration at low rpm where it is most needed. The stronger low end of the Surbo empowers the engine to take off instantly and reach a speed where the supercharger starts compressing the air.


Turbos have an inherent lag, depending on the compression ratio, and transmission. While modern turbo engines have higher compression made possible by high pressure fuel injection at the last moment before firing, they are usually smaller in size due to carbon reducing targets, and so lack strength in the higher gears, especially if they have outputs of just around 120 bhp or less. The usable power is much less at a low rpm than a normally aspirated engine, due to turbo lag. The Surbo starts compressing the air even from idle, shown by a higher idling rpm. This means thicker exhaust gases, which are responsible for moving the turbocharger. Once the Surbo is activated as the car gets moving, the turbo becomes unusually active, and much less opening of the throttle is required to move the vehicle at any speed. The turbo will be on most of the time, and even without deliberate Surbo activation, due to exhaust gases pushing the turbo. The result is a very lively drive, and amusing G forces for the driver and passengers.

Turbos with CVT gearboxes:

Good examples are the Nissan Qashqai and Pulsar 1.2 turbos. The Surbo will counter the lag from the turbocharger, and the CVT gearbox, and enable the small engine to rev to 5000 rpm easily.


Higher revs are possible with Surbo activation, to around 5000 rpm where diesel self-ignition retards, which is 1000 rpm above the rpm red line. This at part accelerator pressure. The result is a higher rpm to start from in the subsequent gear, which is a stronger position to hit the red line from. Due to the added power, less foot force is required. Less worry about smoke too. A normally-aspirated Peugeot Partner 1.9 diesel with Surbo felt more like it had a petrol engine.


The advantage in torque over petrol turbos means that the low rpm power enhanced by Surbo is exceptional. Get a thrill a minute!


There will be smoother progress due to more torque from the engine, helping it to match the electric motor for torque and so aiding coordination. The electric charger is a load to the engine, so as the Surbo helps the engine to rev higher and faster, it adds to the electric charge. Charging also occurs during braking, so the speed imparted by the Surbo is not wasted.
