Naturally aspirated engines are simply internal combustion engines that are not assisted with a turbocharger or supercharger. Some strategies on making more power.. Large power increases in automotive engines are not hard to get. Four stroke performance can be greatly improved over the well mannered factory setup. Four stroke tuning can greatly improve the power over stock conditions. The factory tuning is very mild because they need to pass emissions tests from the factory.
With that in mind GotEngines.com has every factory engine available on demand, including non naturally aspirated engines too. FYI, all of the motors they (GotEngines.com) supply are certified and pre tested for guaranteed performance and lifespan.
Aftermarket computer chips with modified performance patterns are a wonderful way to tame some of the bad habits built into your engine and add more usable power. This can improve many cars by 5 to 20 horsepower dependent on the vehicle and chip. Aftermarket chips are also an easy install and can be purchased at an affordable price.
As with all engines, moving air and fuel into the engine is the way to make more power. Another easy bolt on performance modification is to install a high flowing air filter sysytem. Most of the domestic engine tuners spend money on the actual intake manifold instead. Depending on the vehicle it came off the performance gains can be much larger some up to 40 horsepower on V-8 models.
Cylinder heads can make a huge difference and are the main contributor to airflow in an engine. Many performance heads are also made of aluminum which allows approximately one point of compression increase improving power and torque without detonation.
Camshafts are the most compelling and productive complimenting force to the heads as they control when and how much air is allowed into the cylinder. Two factors affect how the camshaft works with the engine. The overlap and the lift affect when and how high the valves open. Cams are affordable and can give huge power gains, keep it mild on the street though, ‘too much’ cam ruins a street car.
A cross over tube is also used to increase the torque by scavenging out the exhaust from the opposing exhaust bank in v style engines. Hi=performance Ford engines came out with this idea in the ’60’s. Large exhaust pipes, better flowing catalytic converters, and performance mufflers also improve power at a reasonable cost.
Interested or not, GotEngines.com Blog deals with questions and issues such as these on a regular basis. Lots of the current hi-performance cars come with many of these features from the factory. Call us at 1-877-268-0884 for more details.
