Why choose Surbo? With and without Surbo Achieve red line by 1/2 throttle for manuals, and higher revs than usual for autos! What is Surbo? Surbo price in Singapore

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.

Manuals:

Faster takeoff after clutching in, rapid 3000 rpm, split second Surbo charging with throttle easing, and unlimited revving to the rev cut with half throttle. Vibration on accelerator clearly felt, from the denser air trying to pass through a smaller throttle opening. Quick gearchange, 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 autos:

Instant takeoff, faster than manual cars, because no clutching-in is required! You get a headstart. No wet clutch delay due to sufficient torque to allow full clutching. Light throttle, and smooth gearchange upwards. 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, with a minimum of 4000 rpm at half 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 half throttle. Releasing the throttle makes a back pressure that is sustained by the Surbo, and the car rolls along 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, first gear is attained while doing a u turn, making acceleration afterwards faster than with second gear. This is because denser air is always on standby.

CVT (continually variable transmission):

Faster takeoff, and instead of operating at 2000 plus rpm on a high gear ratio and taking longer to accelerate, the rpm becomes higher at 3000 plus on a lower gear ratio and less time is taken to reach cruising speed. Gear ratios downwards 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.

Supercharged:

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 comes into its own.

Turbos:

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, especially if they have outputs of just around 120 bhp. 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 pushing. The result is a very lively drive, and amusing back massaging forces in the seat for the driver and passengers.

Diesels:

Higher revs are possible with Surbo activation, to around 5000 rpm where fuel feed subsides, which is 1000 rpm above the rpm red line. This at just half 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 again. Due to the added power, less foot force is requied. Less worry about smoke too.

Turbodiesels:

The higher torque figures than even petrol turbos means that low rpm power is very impressive, and high rpm power too, as 5000 rpm is reached quickly and also with less accelerator pressure.

Hybrid:

Smoother progress due to more torque from the engine, eliminating any lack of coordination between the electric motor and engine. The electric charger is a load on the engine when it is on, so the Surbo helps it to rev higher and faster, adding to the electric charge.
