How To Increase Hill Climbing PowerWhen driving uphill, due to the added pull of gravity backwards, your engine will require more torque (at low rpm), or an improved ability to rev, so that the next gear begins at a higher, stronger rpm.
The Surbo, which draws in added air to the engine and packs a pressure even from idle, brings the engine to the rpm limit with just 1/2 throttle! This spare power can be useful when driving upslope. Imagine your car on an incline, where its rear is being pulled down by gravity. If your car was unassisted, you will have to press more on the accelerator than you would on a flat road. With a wide-open throttle, you will end up using most of vacuum, which induces air flow into the engine, and even cause over-fueling, so your car would not accelerate much more. With a Surbo, you won't need to press as much, preserving the vacuum for more revs, so that you can change up to the next gear more easily. The Surbo's air pressure supports the engine, preventing it from losing too much rpm when the accelerator is released during a gearchange, for a quick shift. The resultant rpm in the next gear will be higher, so that there is more engine torque to continue revving up the slope. As the gear ratio between 1st gear and 2nd gear is about 9 to 5, it is advisable to let the Surbo push the engine a bit more in the 1st gear, so that the engine has an easier time in 2nd gear, and up the gears.
Effect for automaticsA customer, driving a Proton Neo 1.6 automatic, said that while stationary on a slope and in D mode, the car would not roll backwards anymore, but would stay still or even move forward. The improved low end would be helpful up steep car park inclines, for example, when paying while exiting. At speed, automatic vehicles with Surbo are also more ready to kick down to a lower gear, thus they are able to stay in the mid rpm range, where both engine and the Surbo are strongest. This would help keep the revs up through bends, which are not unusual in hilly terrain.
