A fixed geometry turbos operation is governed by the size of the turbine housing, and small or large has different power ranges where they are effective. The vane in the Switchblade makes it take off like a small A/R turbine housing, and then opens at a preset boost pressure, making it perform like a big turbine housing. Giving you the best of both worlds, quick spool up on takeoff, and great power on the top end.

• The number one reason is because of boost leaks in your piping connections or in the aftercooler.
• The second reason is because of exhaust leaks ahead of the turbo.
• The third reason is insufficient fuel being supplied to the engine.
• Fourth would be foreign object damage to the wheels in the turbo.
• The Fifth would be from insufficient oil supply to the turbo.

The Switchblade turbo consistently improves fuel mileage by producing less smoke during takeoff and by more efficiently burning fuel.
