Description
Description
-Under the high boost level, the stock actuator's weak spring allows the wastegate to blow open, limiting midrange torque. Bleed orifices make it worse. The problem can be solved by replacing the boost actuator. Kinugawa Big Head Adjustable Actuator holds the wastegate closed for quicker boost, then controls the opening to maintain peak boost for superior acceleration and mid-range towing or pulling power.
*. Quick and controlled boost.
*. Produces massive torque right from idle.
*. Increase diaphragm area and spring pressure.
*. It keeps the valve seated longer, achieving a higher peak boost sooner.
*. Crisp acceleration and more mid-range pulling power.
Application
- Single and dual ports exchangeable. 2 IN 1 integrated spring pressure, 3 PSI inner / 7 PSI inner / 7 PSI middle / 11 PSI middle / 10 PSI outer / 7 PSI outer.
Rod Spec
- Rod length: 130mm, 150mm, 165mm, and 180 mm.
Kit Included
- 1 x Dual-ports adjustable actuator head. (15 PSI springs fitted on the head).
- 6 x Spring.
- 4 x Straight rods.
- 1 x End fitting (end hole dia is 6.3 mm).
- 2 x Nut for connecting the bracket.
- 1 x Nut for the rod.
- 1 x Dual-port block fitting.
- 1 x Vice tool.
- 1 x Instruction [download instruction]
Pre-load
- The internal wastegate actuator is designed to have 2mm of preload applied to the rod during installation. Please ensure that it is set accordingly. For a clevis-type application, when installing onto the wastegate valve arms, make sure that there is 2mm of preload, then used compressed air- the amount of air pressure applied should be slightly higher then what BIG Head Actuator spring is rated to.
Situation
- Brand new
- Spring surface paint is used to distinguish color and does not affect the function of the springs.
