The key to efficient intercooling
The key to efficient intercooling:
Torque from Boost
The Engine Control Module (ECM) looks at the throttle pedal and interprets the amount of torque the driver desires. Next it looks at the options it has at hand to produce the torque. One such option is turbo boost pressure referred as "Target Boost Request". The turbo boost pressure is measured at the intake manifold.
Horsepower from Boost
Horsepower is realized by the increase of air molecules in the cylinder / combustion chamber. The colder the air is the more density is possesses meaning more molecules occupying a smaller space. Turbochargers compress air as a means to increase density. The more compression the higher the outlet temperature. The escalation of the outlet temperature flies in the face of the turbocharger's primary principal.
The question is how can we make boost without compressing the air?
The answer is in the delivery system. If we can reduce the pumping force required by the turbocharger and still hit the target boost pressure then we can decrease the turbo outlet temperature before even hitting the intercooler. The turbo can be kept in its efficiency range, come up on boost quicker, and as a bonus have more boost pressure on tap as compared to other intercoolers.
Our unique core construction accomplishes this feat. We effectively decreases the pumping force required of the turbo there by increasing efficiency and effectiveness. It increases the flow efficiency of a typical bar & plate intercooler from 80% to a mind blowing 98%
This technology reduces the pressure drop so much that we are able to increase the fin density and further reduce charge air temperature. Not only that but our cores still lead the industry for minimal pressure drop despite the high fin densities.
We have developed this process of brazing our extruded header bars as part of the core. They are not "tacked on" as an after process. This is also why all of our cores are custom for every application.
Summary
Our intercooler actually MAKE HORSEPOWER time after time. When you press on that throttle pedal, rest assure your power will be there.
