What You Ought to Know about Manifolds?
Whether you believe it or not, there are countless of aftermarket car parts in the market these days and majority of them are designed specifically to improve engine power. One part that a lot of car enthusiasts want to replace is the intake manifold but with so many varieties in the market, making a decision has become difficult. As a matter of fact, it is fairly easy to buy the wrong one and make you feel you have wasted your money.
In order to prevent this from happening, then be sure that you take into consideration the points discussed in the next lines.
It is without a doubt easy to replace intake manifold with a new one and it can benefit the car in a couple of ways. By considering to replace your car’s stock intake with an aluminum aftermarket part, it will help a lot in shedding weight from the engine for most of the stock intakes are made with heavy cast iron. Not only that, the intake may be chosen based on power, RPM range of engine, displacement and also, the weight, ratio, rear end and other parameters of the car. When all this combined, it can sure improve the overall car performance.
Intake manifolds can be divided into two categories and it is either single plane or dual plane, which largely depend on how it’s designed. In single plane intake manifold, it has open plenum which allows four barrels of carburetor to feed the cylinders. In dual plane, this uses a split plenum that is separated by divider wall and allows both side of carburetor feed the four cylinders. Generally speaking, dual plane intake is more capable of improving the lower RPM torque however, this will sacrifice the upper RPM horsepower. Single plane intake is somewhat the opposite as this is creating an effective high RPM power but compromises the torque or at minimum moving peak torque to higher RPM.
Basically, if the engine of your car has mild compression and stock camshaft or if your car has an automatic transmission, stock torque converter and low gear ratio, dual plane intake is going to be a smart choice. But if you’re driving a car with 4.88 gears, high compression, big roller camshaft and loose converter, then you will definitely do better with a single plane manifold.
All manifolds when installed in your car as an upgrade will surely do awesome things but, you have to ensure that it is the right fit for your car’s engine to fully maximize its benefits.
