Ways to increase engine performance
Posted on: 29/Sep/2018 2:51:36 PM
With the advancement in internal combustion engine, there are a lot of new promises and features getting introduced. This includes gasoline additives, miracle lubricants, fire injector spark plugs, and more. However, each one of these comes with its own disappointment.
So, to achieve the best horsepower out of the engine and boost its performance, here are ten quick tips.
Longer life with synthetic lubricants
Synthetic lubricants help in bringing down friction and help the engine have longer life. Comparing conventional oils and lubricants, there is break down happening at times of high heat and high stress when you use conventional oils. Synthetic lubricants are not so. These lubricants also act well during cold weather conditions and offer excellent temperature protection.
Ignition
In the past 20 years, most of the ignition systems require very less maintenance. Unless we get the alert to check, we dont do it at all. It is a fact that car maintenance should also have an ignition system. And we ought to periodically keep changing the spark plug. When its high time to change the ignition parts, go for best ignition components available in the market the coils, wires, spark plugs, etc.
The best way to maintain the car healthy with the aftermarket parts is with the use of original equipment grade.
The underlying reason precision ignition operation is nothing but power. When there is a misfire or lackluster light off, it directly implies that there is loss of power, fuel wastage and increase in emission of tailpipe. When there is a spark arising out of ignition system, it definitely makes a difference in power regardless of how small it is. So, this results in increase in horsepower.
You also need to be very careful with the ignition timing as excessive of the same may harm the engine.
Throttle body and injectors
There will be increased horsepower out of a high performance throttle body. Based on the engine type, you may obtain horsepower of 10-20. It is not that all the engines will be suitable for large throttle body. Hence, you will have to do the necessary homework ahead. Surf the web to discover how others using the same engine are dealing with the same and get an idea out of them. Importantly, larger throttles need higher fuel flow. Injector and throttle body are directly proportional.
Seek help from any reputed dyno tuner and get the needed adjustments in fuel and spark curves. This will alter the throttle body and increase horsepower.
Compression
One of the most helpful ways of increasing horsepower is through compression. Increase compression and ultimately increase the build in power. In the many years involving internal combustion, there is no better way to uptick power.
Note that you need to be very cautious when you increase compression. Both compression and cam selection are going to have direct impact on cylinder pressure or the working compression.
For both these cam selection and compression, the best person to advice you is an engine builder. These need to be carefully curated so as to reap maximum benefitits without causing any damage to the engine.
When the compression is beyond 10:0:1, it may lead to detonation, pre-ignition or spark knock or pinging. When you increase compression, have an eye on the fuel and spark curves.
Extra power
Actually, in reality, there is more power being produced by the engine than what it really delivers. There is a lot of power getting lost due to internal friction, the components involved as they consume power to get moved. There is also a lot of heat getting dissipated to the atmosphere. About 70-75 percent of the total heat energy sourced through fuel are getting wasted. The tailpipe emits 50 percent of it and 25 percent through the cooling system. Only 25 percent of the British Thermal Units are getting harnessed at the end of the day.
Here is how you can get more power by bringing down friction
Roller tappet camshaft, dual roller timing set, piston rings with low tension, improved wall clearance between piston and cylinder, roller rocker arms, tray with wideangle, etc. are some of the ways.
Do you know how much power actually gets wasted out of the car driveline? It may be a sick idea, but these are to be taken into account! When the contact patch is more, the car drives more power. When the tires are not properly inflated, you will feel like as though the car is tied to a tree and tough to accelerate the vehicle. The tire inflation has to be up to its full limit based on the ambient temperature. There is definitely a direct impact of temperature on pressure.
Velocity stack
This is nothing but a device in the shape of a trumpet. This is generally fixed to the intake system of the engine where air flows in, or it is fitted with the fuel injection or carburetor. This primarily improves flow of air. This brings down turbulence and hence results in better horsepower.
Right sizing of the fuel line
This may sound weird, but it is highly important. There is no possibility of getting about 450 horsepower out of a 5/16-inch fuel line. The minimum limit for fuel line is 3/8 inches in almost all the applications. When there is more than 500 horsepower, you may have to set as 7/16 inch fuel line.
Dual plane manifold
When you often focus on the horsepower, the same importance is often missed with the torque. This is your best pal when you are on the street and horsepower is not so. There should be smooth torque to get horsepower at the throttle.
Try out the jet size
There can be either way functioning of the dyno testing when we consider power. When there is too high or too little of it, there can be loss in power and that is why we suggest picking the Holley jet kit. Increase the jet size and find the difference. Start with the primaries and move on to secondaries.
Head of the cylinder
Of all the parts, the cylinder head is the section we often consider to be modest. When there is good cylinder head, you will obtain more power when you are right at doing it.
