By default, most stock engines cannot operate above 85% volumetric efficiency. There are a variety of reasons for this. First, internal combustion engines are intrinsically limited by the air pressure that surrounds them. Even in ideal, low-altitude, low-temperature conditions, atmospheric pressure is never high enough to induce peak performance. Multi-valve cylinders and variable valve timing have helped boost efficiency in some late model cars, but many domestic engines are limited to two valves per cylinder with fixed timing. What's a power junkie to do?
Since increasing the overall power of their car or truck is the number-one priority for most of our Houston customers, HP Motorsports LLC offers a wide range of power adder options alongside dyno tuning. By themselves or in combination, they can significantly boost the performance of your engine-and not all power adders require an overhaul of the engine.
Bolt-on power adders can usually get you to 90% volumetric efficiency-or even a bit higher, but the only way to get to 100% is through a forced induction system. By forcing more air into the cylinders, a forced induction system can boost the horsepower of the average street engine by 150 horses or more! One system-known as a turbocharger-channels exhaust flow to generate a tremendous amount of power when the engine is turning at 2,500 rpm or more. For more instant throttle response, a supercharger utilizes a belt-driven blower to deliver its power boost with less delay.
To discuss what power adders make the most sense for your car or truck, call HP Motorsports at (281) 492-0645. The options are almost endless!
