What is the first rule of boost control?
Set your boost cut limit. Mistakes happen, Failures occur, and the cheapest Insurance for any setup is ensuring you incorporate a careful setup boost cut limit. Unsure what this is or how to do that? Then we recommend reaching out for professional and qualified assistance.
Will this Wastegate fit my existing manifold?
Turbosmart External Wastegates are designed around peer flange orientation, meaning: Yes. If you have a 40mm valve, then our 40mm CompGage40 will fit & the same goes for the 45mm HyperGaet45, ProGate60 etc.
How do I change the spring(s)?
You will need the locking collar tool as supplied in the box. You also need to observe the instructions and apply pressure to the top cap before removing the collar - This is part of the design & an important anti-vibration measure.
What size are the reference fittings?
The reference ports are 1/16” NPT. We have a range of AN adapters and high temp push-lock fittings available in the Spares and Accessories Tab.
What am I doing wrong? The valve seat does not seem to sit flush to fit the clamps.
Your Turbosmart External Wastegate is designed to have pre-load, and you will need to push down & apply a small amount of force (the higher the base spring pressure, the higher the force) the get the V-band on. It is designed this way to ensure maximum seat pressure.
Why has my Wastegate housing changed Color?
Heat in your engine bay can affect the anodized finish of your wastegate. This does not necessarily mean it will ever affect performance or reliability. Engines & engine bays get extremely hot sometimes, and this discolouration can happen over time and use. Suppose it has happened particularly quickly, however. In that case, it may be worth looking at your setup and ensuring adequate airflow to the wastegate - There is a difference between use and abuse.
I cannot get control of the boost. What is wrong?
The number 1 issue with boost control is the reference/hookup method. Get back to basics: Try using the simplest hookup method (Boost Reference to the lower port of your actuator) and performing a power run. What boost did it make?
If you are making the boost the springs fitted would suggest, then the gate is working as expected, and you need to look at your hookup method and boost control strategy.
If you are making less boost, you must check for leaks in your pipework and hoses.
If you are making more boost, then you look at your manifold design for gate priority or the actual size of the gate you are using versus the bypass requirements.
