intercooler fmic kits for turbo cars

    INTERCOOLERS

    Fresh ways to cool out your car... 

     Generally speaking after market intercoolers are a quick and easy way to upgrade your car for a stage 2 tune. Things start to become quite hot at that point so a good FMIC is a wise choice. They are often larger and can be placed in different positions on some models compared to OE. Improving airflow to your intercooler also has benefits for turbo cars. This might be why mesh for bumpers is quite popular.

     

     Fin density which is of typical bar n plate design should be balanced to a point, going too extreme on the number of fins will drop the pressure behind your intercooler. Why is that important? High pressure passing over and through the front of the car across the FMIC exits faster when there is high pressure on the other side. Too many fins effectively cause a barrier to what volume and rate of air you can flow over it so to cool your turbo charged air inside your front mount.

     

     To fit an intercooler can require a minor bit of trimming & cutting so that your bumper and under-tray has room for your new cool beast with all its alloy pipes and silicone hose glory. Installing can take anything from 2hrs to days depending on your skill/experience/problem solving ability/knowledge as the cars bumper generally has to come off. This entails getting behind the wheel arch liners and finding all the places the bumper is fixed to. After that comes working out which pipe goes where, especially after the layout of your new air to air intercooler can be a little different than OE was.

     Size of intercoolers is also a factor, bar n plate design is good for higher pressures from the turbo going inside it and passing through it. As that hot compressed turbo gas travels from one side to the other inside the FMIC, due to the size of the volumetric space its now travelling through the pressure drops. This increases the likelihood of more oxygen molecules being able to join the chain since the molecules are not packed so densely together. This is good right? Yes and at the same time imagine you boosted at 1.0psi on your previous OE cooler, car might have been shooting 10% higher than that so to achieve it by the time the gasses get into the cylinders. They might now with an aftermarket intercooler travel through longer pipework, sometimes larger in diameter and then through a larger intercooler. Then owners might have 0.8-0.9psi going into the cylinders albeit cooler than before. A remap can help dial out some of the lag a larger system can have. This could be why we hear so much about intercoolers not adding power, they are a safety feature for turbo cars more than anything else, make it larger, pressure drops, there's pros and cons to both. Engine safety is paramount.
