Q

Does the Synchronic Wastegate use a two-piece valve?

Q

How do I fix oscillation with the Synchronic Wastegate when controlling with a solenoid?

Q

How do I set up the Synchronic Wastegate?

Q

How do I use a boost controller with the Synchronic Wastegate?

A

When using a solenoid to control boost, there should be no need to use the top ports of the wastegate.  This is only necessary if you are trying to achieve very high (30+ psi of boost pressure and/or are faced with very high backpressures)

The diagram below is based on the use of a standard 3-way, 2 position MAC valve.  This is the same valve used by AEM.

Solenoid Basics:
Port 1 - Control output port
Port 2 - Normally closed inlet port at rest (Cannot blow through to Port 1 when solenoid isn't energized/0% duty cycle)
Port 3 - Normally open port at rest (You can blow through to Port 1 when solenoid isn't energized/0% duty cycle)

Most of you that are familiar with boost control setups, will realize that this is setup as an interrupt manual boost controller.  This means that the pressure source is being regulated to the wastegate to "trick" it into thinking that the system is making less boost pressure than it actually is. 

Using a bleed-type manual boost controller that is tee'd into the boost line to the WG will not be effective with the Synchronic wastegate no matter how much air pressure you bleed away from the WG.  The Synchronic WG is far too responsive to pressure signals to be fooled by a simple drop in mass volume in the control signal.  This is why most OEM systems have to use a restrictor orifice in order to make a bleed work on an OEM car.  Besides, the compressor of a turbo can keep producing flow to compensate for the bleed.  You may be able to use a bleeder type boost controller that has a ball&spring gate. 

Q

How do I use the various ports on the Synchronic Wastegate?

Q

I can't make the desired boost pressure, and I have tried both springs that came in the box.

Q

I'm trying to take apart the wastegate, but the valve is not separating from the piston.

Q

I’m experiencing boost creep with my Synchronic wastegate, how do I fix it?

Q

What are the dimensions of the Synchronic 40mm WG?

Q

What are the dimensions of the Synchronic 50mm WG?
