Turbosmart Straight Gate

By: J. R. Crosby

Turbosmart had a very big release this year at the SEMA 2022 show.  While last year they released fully electronic wastegates, this year they were able to take that design “one step further”, and go to what they are calling the “straight gate”.  Take one look at the wastegate itself and its clear to see where the name comes from.  The gate itself is straight.  So lets dive in and see what’s going on here:

For those that don’t know, a typical external wastegate has the routing of the air going at a 90 degree angle, so that the air is required to go up past the valve and then turn 90 degrees to flow out.  Almost all external wategates have been this design do to packaging and having a diaphragm that can lift the valve open and closed.  With the Turbosmart gate being an electronic design that twists the valve open instead of pulling it open, it allowed the engineers to get creative.  And while it would have been neat just to have a different design that might have offered different packaging, this design offers something even better, performance.  Because this gate can be designed straight, the flow of exhaust is not required to bend at a 90 degree angle before exiting, but instead can flow straight.  Turbosmart claims that this gives this wastegate the ability to flow over 60% more than any other wastegate of its size on the market! 

Before you get too excited though, it is significantly larger than the mechanically designed gates.  It also requires an external controller or an ecu with the ability to control an external wastegate.  And like most things, with performance comes cost.  Turbosmart didn’t quite know retail price of the gate yet, but said to expect something around $850+ dollars.

All this aside, for the right person looking for the most control and best flowing gate on the market I think its safe to say the turbosmart Straight Gate, is the current winner.
