Aftermarket Intercoolers for 991 Power Boosts

Stock intercoolers on Porsche do not allow for peak performance. The stock intercoolers on these vehicles have a small frontal face and a basic design compared to certain aftermarket intercoolers. The main side-effect of the stock design is a decrease in engine power output.

When dealing with design of 991 intercooler performance parts, simple can be good, but basic can always be beaten.

When the surface area of an intercooler is small, incoming air isn't effectively cooled. In order to decrease the temperature of incoming air, a front-mounted intercooler must have a large surface area, an expansive core, well-placed fins, and rounded end tanks.

Before discussing how select aftermarket intercoolers can boost power outputs in Porsche 991, it's necessary to review how an intercooler works in a turbo-charged vehicle. 

An intercooler mounted in front of a turbo-charged engine receives the hot air from the turbocharger and cools it. The FMIC is an air-to-air intercooler, which means that cool air from the atmosphere is used to cool hot air from the turbocharger. As the hot air moves through the intercooler, heat is absorbed by the fins of the intercooler and cooled by the atmosphere. The fins of the intercooler break up heat molecules that allows for quicker cooling. The air that then enters into the engine from the opposite side of the intercooler is full of oxygen. More oxygen equals more gas in the engine's cylinders, which means... more power!

Depending on the design and integrity of an intercooler's construction, it can reduce intake air temperatures in a car. When it comes to deciding on an intercooler, it's good to do some research. Check out car-specific forums, performance reviews and ask fellow car enthusiasts around town.

Many Porsche aftermarket part developers copy designs from original innovators and use subpar materials for construction. If you take a little bit of time to research for intercooler, you'll notice very quickly the difference. 

Cool air is great and all, but what does this cooler air amount too? Basically, what every petrol head craves - more horsepower.

An ideal 991 intercooler cools air from the exhaust side of the engine and presses it through to the intake side of the engine, unrestricted. Because of the design of all intercoolers, there is a slight pressure drop from the exhaust side to the intake side. With stock intercoolers and illegitimate aftermarket ones, this pressure drop is significant enough to affect engine power output; however, with top-of-the-line intercooler, pressure drop is negligible. 

The combination of low pressure drop and an abundance of cool air translates into increased horsepower.

You can also expect an HP gain in your Porsche model after its equipped with a performance-grade intercooler depending on the condition of your vehicle and existing modifications.
