    Hey guys! I need help!

    What are some high boost proven DBW throttle body options? The most popular proven TB I can find is the Bosch 82mm. Does anyone know of 90mm or larger options that work in a boosted application? Some of the LS TBs I found in the 100mm range said max 25 PSI which is concerning.

    I am just trying to do some homework instead of leaving everything up to my engine builder. Thanks.

    Bigger throttle bodies are easier to blow open/not close properly under boost pressure, they need stronger return mechanisms which means a stronger motor/gearbox which is where aftermarket throttle bodies come in.

    I saw that TB on the Magnus site. Been wondering how people are wiring this up to work on a DSM. I've done some searching, but so far I've only found some generic bench applications on youtube.
    Anybody have any wiring info or a thread to point me in the right direction?
