Increasing air flow and compression from low rpm, the Surbo (air suction-turbo) improves engine torque, resulting in a light feel accelerator, for quick acceleration and fuel saving. Driven faster, it brings the engine to its rpm limit with just 1/2 accelerator pressure! You'll never have to floor the accelerator again, thus avoiding wasted fuel, harmful carbon deposits, and excessive emission.
ADVANTAGES FOR ALL VEHICLES:
10% fuel saving in city driving and more on highways, due to less accelerator pressure required for the same speed.
Higher rpm capability, more torque and bhp over a wider rpm range.
0-100 kph acceleration time cut by 1 second for faster cars and up to 3 seconds for slower cars.
Higher top speed by up to 30 kph for the average 1.6 sedan (as reported by customers).
Less CO2 output due to less fuel required for the same rpm.
For automatic vehicles: instant acceleration from rest with no torque converter slip due to increased engine torque. Higher rpm possible with 1/2 throttle in D mode to between 4500 rpm and rpm limit depending on gearbox, and quicker changes to lower gears. More info and auto car list..
For manual vehicles: achieving rpm limit with just 1/2 throttle, and even higher rpm if the rpm limit is removed for racing cars. More info and manual car list..
For diesel vehicles: better load capability, less diesel black smoke because the accelerator is pressed only halfway for the engine to reach the rpm limit. Helps prevent clogging of particulate filters. More info and diesel car list..
For turbocharged vehicles: reduced turbo lag, improving turbocharger performance. More info and turbo car list..

By adding a Surbo, your vehicle becomes quicker. Here's how:
1. The Surbo gives more torque over a wide rpm band. Torque means instant twist power. The engine with Surbo on can accelerate briskly and sustain the acceleration to red line or beyond, all on half throttle or less. That means easier pickup, and fuel savings because you will press less on average (by mathematical derivation on Wikipedia, the amount of fuel injected at any moment is proportional to number of cylinders x rpm x accelerator pressure). With Surbo, although you will rev higher, accelerator pressure required is less, and as you are faster and will spend less time in the acceleration phase, you will get to cruising faster, so you will save more fuel.
2. The Surbo delivers higher power (which is proportional to rpm multiplied by torque at that rpm). If your car starts slowing down by 4000 rpm, it's time to restore the power. The Surbo takes your engine back to red line (rpm limit) easily and puts back some 50% of existing acceleration power based on rpm, assuming a red line of 6000 rpm. Or, instead of travelling 40 metres, you travel 60 metres in the same time. You'll realize this when you start beating familiar traffic lights. Up the gears you will pull even further away from other cars as they start to slow by 3rd gear. This is because these drivers have to press the accelerator more for higher gears, and use up most of the manifold vacuum for air suction, and perhaps even encounter knocking and over-fueling. The Surbo, with its own vortex suction power, uses less of the manifold vacuum to pull the air in, so extending power.
3. The Surbo assists hill climbing. Just going up the incline, activate the Surbo
for extra air compression to charge up the hill. This makes the Surbo useful for long hills like those at Seremban Heights in Malaysia. There it starts with just a moderate slope that attracts little attention, but after that there is a bend and a sharp uphill climb. Many drivers and cars are not prepared (for example, by picking the correct gear and charging up the slope with speed). The wide-band torque of the Surbo gives added flexibility. The driver can maintain a low rpm in a higher gear for longer, or he can shift down to use the high rpm power of the Surbo too. The Surbo is also useful for mountains like the Genting Highlands, where air density and hence oxygen content drops with altitude. For every 100 metres climbed, engine power falls by 1 percent. The Surbo when activated gives improved air density for efficient combustion.

4. The Surbo assists the engine to overcome loads like the airconditioner. The low rpm power of the Surbo helps, as that is the region most weak vehicles are stuck in while trying to accelerate. Once the Surbo takes care of the aircon load, it can just power away up the revs, allowing gearchanges upwards and gaining speed, till the aircon is less of a problem.
5. The Surbo gives you confidence to overtake quickly. Especially long vehicles which have blind spots, or a whole convoy of vehicles unable to pass them.
Just accelerate and hold the accelerator briefly to back pressure the Surbo for a vortex, and when the accelerator vibrates indicating increased engine power, start accelerating with half throttle to high rpm, and repeat in the next gear if necessary.
7. The Surbo gives you freedom to speed without fuel penalty. Where legal, you'll achieve your vehicle's rated top speed with less than full throttle, or you can be cruising at
150kph with about half throttle. Our customer feedback shows
that the speed for maximum economy gets stretched from the usual 90 kph to 110 or
120 kph, despite wind resistance increasing as a cube of the speed. For example, a Surbo Civic ESi cannot better 12 km/l in Singapore but will do 17 km/l at 110 kph on the Malaysian North-South Highway. Its engine rpm at that speed was near to the Surbo's torque peak rpm, at around 3300 rpm.
The increase in the top speed will be especially noticeable if your car has accumulated a lot of mileage (which causes the air flow to be less due to worn valve cams or carbon), and needed a lot of accelerator pressure to run fast. The lighter throttle also reduces fatigue. Your own body will feel the tickling of Surbo-induced acceleration, and your passengers too will get a gentle back massage througout the drive. Surbo is lots of fun. Get yours today!
How Surbo works
Due to gaps along the air intake and connected tubes and chambers, air suction is not entirely directed at the air filter. Not only is air velocity through the air filter not as high as it can be, the gaps mean some of that air will not enter the engine for combustion. To create more air suction, the accelerator has to be pressed more, causing more fuel to be injected, resulting in over-fueling that can cause hesitation, and even knocking. The rpm achieved may not be very high. Some fuel is wasted, often in the form of emissions.
A shortage of air causes automatic gearboxes to shift up too soon, because in a higher gear, the engine requires less air. This also makes downshifts more difficult, as the engine requires more air for higher rpm in a lower gear. So, often the accelerator has to be pressed deeply to allow more air into the engine to induce a gear shift down. The result is wasted fuel, increased emission and foot fatigue for the driver.
In a petrol engine, when the accelerator is pressed more, the vacuum in the engine manifold drops. However, the vacuum is the force that draws air into the engine. The moment the accelerator is pressed fully, the vacuum is minimized, and air induction force is depleted. Also, with the accelerator on the floor, fuel injected is maximized and over-fueling and hesistation occur. Acceleration quickly becomes zero for the gear, and a gearchange up is necessary for further acceleration. Acceleration begins to slow significantly from third gear, and in the top gear, the rpm limit cannot be reached. Therefore, the top speed of a typical 1.6 litre sedan is only about 190kph.
During installation of the Surbo, the gaps in the air intake and connections are covered. Less accelerator pressure is required to pull the air through the air filter and into the engine, so less rpm is required to achieve sufficient torque. The lesser fuel injected due to less accelerator pressure means over-fueling and knocking are prevented. More air goes into engine for proper combustion. So, acceleration becomes faster initially, so much that some of the added momentum and time saved can be used to compress air through the Surbo, for even more power. How so?
By slightly easing pressure off the accelerator for 1 second, a backward air pressure is formed towards the outlet of the Surbo, causing it to twist and jet air at its outlet to match the back pressure, and to spin air into itself with a vortex to maintain the compression. Upon subsequent acceleration, due to the back pressure ahead, the Surbo continues to jet and its vortex continues gorging air into the engine, so that the rpm limit is achieved with just 1/2 accelerator pressure!
When the air is charging between the Surbo and the engine, the engine also puts out exhaust gases of increased pressure, thus helping the exhaust system to blast out the burnt gases from a lower rpm (which aids low end torque). For turbocharged engines, since the turbocharger is driven by the exhaust, the response time of the turbo is reduced so the full turbo effect comes earlier and with less effort.
For automatic vehicles, since the Surbo feeds the engine with more air, the engine is allowed to rev higher before changing to a higher gear, and this gives more speed and makes better use of the original max engine torque available at the upper mid rpm range. Similarly, due to more air on standby, downshifts are easier to induce with just a slight press on the accelerator. Once the Surbo is on, a second downshift can also be induced for even more acceleration.
Since the accelerator is never floored, sufficient manifold vacuum draws air into the engine forcefully, so acceleration is extended till the rpm limit is reached. Often, the Surbo-assisted vehicle is so strong that it will reach the rpm limit even in the top gear, and top speeds of 220 kph for 1.6 litre sedans are consistently reported by customers.
As the accelerator never has to be floored, emissions are kept low. All the fuel is used properly for better acceleration or fuel economy.
