How To Get Higher Engine Rpm

Below is a testimonial from the owner of a 4AT Nissan Latio with Surbo:"My dad in law says more power. RPM can hit almost 7000 rpm haha."

To get higher rpm, there must be faster air flow, so that the pistons are not held back. The Surbo helps to take in more air, to push the pistons to a higher speed.

1. After initial acceleration, upon slightly closing the throttle, the Surbo spins air within itself into a suction vortex (a pull force) and outputs the air as jets (a press force), and a third (suction) force comes when the accelerator is pressed again. With three forces, air passes through the engine faster. By 1/2 throttle, the engine will reach the rpm limit! This tug-of-war is won easily!

At this rpm limit, the fuel cut-off will occur for most fuel-injection engines. For carbureted cars, there is no such limit so the revs can be extended straightaway. For diesel vehicles fitted with Surbo, the red line on the rpm meter is achieved easily with the accelerator pressed halfway, and many achieve 5000 rpm.

The Surbo also helps automatic cars rev higher. Automatic gearboxes normally change up at 3000 rpm in D mode. However, the Surbo extends the revving in D mode, with half throttle sending the rpm meter to at least 4500 rpm for most makes, and even to the red line in the case of Kias and Hyundais, which have rather sporty gearbox programs.

For continuously variable transmission (CVT) cars, the rpm will go to 3500 rpm instead of 2500 rpm during acceleration, shortening the time to get to speed. At cruising speed, due to increased torque from the Surbo, the rpm may go lower than normal, indicating a higher gear ratio, but as soon as acceleration is needed, a light prod on the accelerator will cause the rpm to rise again (gear kickdown) for faster pickup.

Racing application for manual cars

If the rev limiter is removed, the revs can be extended by stepping further on the accelerator. At the original red line, since only half throttle is used, this means that a large part of the engine vacuum is still unused, and this can be used to pull more air into the engine, thereby extending rpm.
