In a forced air induction system by raising the intake and lowering the exhaust it gives you an opportunity to increase cylinder pressure by decreasing the amount of air/fuel mixture that escapes out the the exhaust. Also, in a forced air situation you create a longer more consistant burn and with the lower exhaust port you are able to utilize that energy longer before it escapes out the exhaust port. By doing this you add significant torque to the low end and you are able to transfer in and out of boost more affectively. I would absolutely support the idea of a turbo specific ramp as well. The TRA concept is great in the sense that you can change how the clutch loads the motor by more than just adding weight. It adds a new dimension to tuning that helps with the non-linear power curve that a turbo creates. There are obviously some quality and durablity issues involved with the TRA but I don't think there will be any issues on an XP if set up properly. That's how I've come to understand things anyway.
