Improved Performance Through Greater Torque

Here are some speed tests, done mostly by customers, and these show better all-out performance, though our main emphasis is on improving everyday driving.

The following cars have been recorded at speeds higher than their original top speeds:

Make Of Car	Original Top Speed	Highest Speed With Surbo	Achieved In Gear	Remarks
'01 Citroen Berlingo 1.9 Diesel	130 kph	140+ kph	4th or 5th	With aircon on
'89 Honda Civic 1.3 GL	170 kph	185 kph	5
'97 Mitsubishi Lancer MR 1.6	210 kph	220 kph	180 kph in 3rd	Richard Wong
'93 Opel Vectra 1.6	190 kph	205 kph
'98 Proton Wira 1.6A	160 kph	180 kph	4	K H Tan
Peugeot 106	115 mph	118+ mph	5	UK-Cruise
'89 Peugeot 405 1.6	180 kph	188 kph	5	3/4 throttle only
Proton Putra 1.8	208 kph	215 kph	5	limited by gearbox
'96 Rover 416 HHR	190 kph	220 kph	5
'95 Skoda Felicia 1.4	96 mph	100 mph	5	Peter Allen
Toyota Starlet 1.3 16v turbo	120 kph	150 kph	3	Chris of Kota Kinabalu
Toyota Starlet '89 1.0	150 kph	170 kph+	5

(The reason why top speed is higher is because using the Surbo, the accelerator need not be floored to reach the original top speed, so there is still a vacuum in the manifold drawing in air for acceleration. For everyday use, it just means easier cruising and fuel saving because cruising speed is a fraction of the top speed)

The following cars have improved acceleration times:

Citroen Xantia VSX 16V 2.0 9.0 secs 6.57 secs 2nd 0-60 mph

Kilowatt Per Tonne vs 0-100 kph Time. This graph is the best judge of performance, according to Autospeed.com. Thanks to David Barker (Citroen VSX) for his contribution. Calculations on this chart shows that his car's power-to-weight ratio has improved from 119 bhp/tonne (BBC Top Gear Jun 94) to around 185 bhp/tonne.
