Mustang MSD Distributor Upgrade

Upgrading an old points type distributor to a hei which stands for high energy ignition can be a rewarding upgrade. This distributor is on a 1966 ford mustang with a 289 v-8 engine. The upgrade distributor is a msd unit made specifically for this engine, some people may use a distributor off of a newer model ford engine. Unlike points you will never need to adjust a high energy ignition because it will never degrade. The engine will run smoother due to the higher energy spark sent to the spark plug. The cylinder combustion will be much more complete due to the increased ignition spark energy of the new distributor.

Intercooler

Category: Auto Tuning


Intercoolers have been used on turbocharged and supercharged engines for quite some time now. When used on a supercharged engine they are often called aftercoolers. Turbos are the most common usage for intercoolers though. Any engine that uses an air compressing device such as superchargers and turbos can benefit from intercoolers. When the air gets compressed it can heat up dramatically, up to 300 degrees F. This dramatically reduces the compressed air density and limits the maximum boost. The high intake temperatures can increase the chance of detonation in the engine, causing major engine damage. An intercooler can fix this problem.

Supercharger

Category: Auto Tuning

Engines are simply an air pump. The more air you can get in and the more exhaust you can move out, the more power you can make. Superchargers are one way of packing more air into an engine. Superchargers or blowers as they are sometimes called have been around for a long time and are still currently being used on some production vehicles. There have been many different types of superchargers made but I will focus on the two most popular versions. One being called positive displacement or roots type and are generally referred to as blowers. These are the style most used on muscle cars due to the ease of setup on a v-8 with a carburetor. They are also widely used on drag cars for street and professional racing. Some of these cars make insane horsepower in the thousands. The blower has an advantage, because it compresses air even at very low speed it also creates alot of torque. This gives the engine very good response and power from idle up. That is why drag racers like them so much, they are very predictable from launch and have almost no lag time.

na performance

Naturally aspirated engines are simply engines that are not assisted with a turbo or supercharger. Most people that want their car to go faster will chose this way. Large power increases in automotive engines are not hard to get. Four stroke performance can be greatly improved over the mild 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. Many people buy aftermarket computer chips with modified performance maps. This can improve many cars by 5 to 20 horsepower dependant on the vehicle. Aftermarket chips are also an easy install and can be purchased reasonably. As with all engines, moving air into the engine is the way to make power. Another easy bolt on performance modification is to install a high flowing air filter. Large gains can also be made with improved flow through aftermarket carbs or larger diameter throttle bodies. The import tuners usually purchase high performance intake tubes which try to draw in cool air. These kits usually give moderate performance gains. Most of the domestic car tuners do the same and tend to 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.

oil pans

Category: Auto Tuning


Oil pans seem like a simple engine piece that should require no thought. The truth is that the oil pan can be a very vital engine part. Different engine have different needs. If an engine is stroked the oil pan may need to be deeper than stock for rod clearance. If the new pan is deeper the oil pickup should be dropped the same amount of distance. Many other modified engines also use deeper pans that hold more oil. Larger pans mean more oil that will stay cooler and take longer to break down chemically.
