I'm sorry for this, I hadn't updated the corporations thread yet. Twister Mk.2 generates Hot/Cold Air with great efficiency, So you can have, in the same plane, separated systems for both high and low performance. The turbocharger main function is to increase the amount of AirIntake/ATM/Cold Air generated per second. Also, it makes possible to run engines at high altitude, or at Layth, since it increases the amount of air provided to the engines. The reason why they have only 1kN is because they use an "engine module" to work.:D:D P.S.: When I first uploaded the upgraded, I was a little busy, I intend to upgrade the thread soon.
