Frequently asked question: What's the difference between the single Surbo and the Twin Surbo?

1. The main difference is that the single Surbo has a torque peak at around 3300 rpm, while the Twin Surbo at around 2800 rpm. Your choice will depend on your your usual operating rpm. For a more detailed comparison check out the Dynamometer Test Results. The other difference is that the Twin Surbo requires twice the space to fit, around one foot of free space, so it's often fitted at the air filter inlet, in which case the filter element inside must be original to ensure a perfect seal.

Advantages of the Twin Surbo:

1. The Twin is stronger than the single Surbo between 2500-3000 rpm by 10% according to the dyno test results, so you won't need to rev much and can change gear upwards sooner. Usually there will be another 5% more fuel saving if you had gotten 10% fuel saving with the single Surbo.

How to get a Twin Surbo:

To ensure the Twin Surbo works, have one Surbo fitted first to test for power and economy, with ensures that there is no leak, and then add a second Surbo for a Twin Surbo if space allows. Ask the installer to add another Surbo in a straight line only as the two Surbos must work in series, where space allows (see photos above).

Some observations

The Twin Surbo has faster acceleration:
'95 Mazda Astina 1.6 (9.6 secs to 100 kph when new) clocks 8.9 secs with Surbo and 8 secs with Twin Surbo (recall that the Twin has 10% more torque between 2500-3000 rpm, where the Surbo can be activated from).

Twin Surbo '92 Peugeot 405:
A friend from China driving it for the first time unknowingly moved it from idle using the wrong gear--3rd. In the morning or on a cold start (1250 rpm idle) the car will move in first and second with foot off the accelerator. Once warmed the car keeps moving in second gear on a flat road, with no pedal pressure. This shows an increased air pressure accumulation and improvement in the ultra low end. In a long traffic jam, it continued to move easily in first gear without throttle pressure at 750 rpm, even up slight slopes and with aircon--just using idling fuel. The car also managed to climb, in 5th gear, the 10-storey high Benjamin Sheares bridge, approaching at less than 90 kph from the winding and steepest side from Rochore in 5th gear, easily reaching the top at 2000rpm or about 73 kph. For 0-60 mph testing, the time was cut from 14.2 secs to 11.78 secs, same time as for the 1.8 405 so it seems the Twin Surbo adds about 200cc.

Fuel Savings

Result for the Honda Civic ESi, and the fortnight after. Another improvement. Dr Ngoh of Renault Club also had improved economy on his Renault Megane 1.4, up from 13.5 to 14.8 km/l (50/50 highway/city driving). Toyota Starlet 1.0 saves even more fuel with the Twin Surbo. Mr Din (Civic GL twincarb) also said that with the Twin Surbo and carb tuning to 0% CO, his consumption improved from 7-8 km/l to more than 9 km/l.
'95 Peugeot 405 1.6 (11 km/l originally) returns 12.1 km/l with Surbo and 12.8 km/l with Twin Surbo, improving 10% and 16% respectively. These correspond to the torque increases for engine speeds during cruising for the Surbo and Twin Surbo respectively (see dyno graphs).
