Alfa 155

1. For the petrol manual version: quick revving to red line on the rpm meter with half throttle, faster 0-100 kph acceleration, higher top speed, and hence easier cruising. Therefore, fuel economy improves, especially on the highway. There will be a wider torque spread, with a higher torque peak at a lower rpm, and more bhp.

2. For the automatic version: instant acceleration from standstill as there is more engine torque so no slip is required, higher revving than the usual 3000 rpm with just half throttle, or the ability to change gear up at a lower rpm due to sufficient torque, quick gear kickdown by pressing the accelerator slightly, higher top speed and better fuel economy.

3. For the diesel version: higher revs with part throttle, stronger acceleration, higher top speed, less black smoke, greater load capability, and improved mileage.

The fitting position for Surbo in the Alfa 155 is in the pipe after the air filter. There is usually no cutting and the installation is reversible. The Surbo is also transferable as it works for most vehicles below 3 litres, because all of them take in the same air; the Surbo raises the air density taken into the engine for higher compression, which increases engine efficiency.

If a turbocharger is fitted or already there in the Alfa 155, the Surbo will help to cut turbo lag as the denser airflow from low rpm of the Surbo will help to spool the turbocharger earlier and bring turbo boost sooner.

The Surbo is really a fun device to have in your engine as it imparts a throttle sensitivity that makes your vehicle seem like a sports car. We invite you to read more about this product, and also tell your friends about it!
