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.
