Computer aided design yields maximum results

Our engineering team designed the Alpha 991.1 Intercooler end tanks with extremely smooth features and geometry for the best flow resulting in maximum horsepower. Designed using Solidworks 3D CAD software, these end tanks have improved flow over boxy sheet metal end tanks found on other intercoolers.porsche 991.1 intercooler modsporsche 991.1 mods


Cooler Intake Charge Boosts Power And Response

Channeling cool air to the intercoolers is vital for optimum performance of any intercooler. Some manufacturers choose to remove the factory intercooler inlets in order to cut costs. This greatly reduces the effectiveness of ANY intercooler whether it's larger or not. Others require that you cut up and tape the factory shrouding to the intercooler core in an attempt to seal the shroud to the intercooler core. While this is better than removing the shroud, it is still not the most effective way to boost performance.

The Alpha 991.1 Intercooler System retains full use of the stock intercooler inlets (located in front of each rear wheel) forcing cool air into our larger, carbon fiber shrouds. Not only is this option more aesthetically pleasing, each rigid, OEM-quality, carbon fiber piece is made to seamlessly mate to that Alpha Intercoolers feeding them cooler ambient air more efficiently than the other alternatives. Not to mention eliminating the removal or destruction of your intercooler ducting.

Maximum Airflow For Maximum Horsepower And Torque

To further improve airflow, our engineering team went a step further by computer designing precisely molded, custom silicone couplers. These provide perfect fitment and optimized geometry for improved airflow volume and velocity providing quicker boost response helping you stay ahead of your competition! Perhaps the best feature about this intercooler system is that it maintains cooling efficiency as more power producing upgrades are added to your Porsche 991.1! It improves the effectiveness of your other upgrades giving you maximum hp output potential!
