I Autowork PNP BOV KIT

We have developed a PNP BOV Kit using Turbosmart RavePort EM valve. 

B58 and S58 engines produce very little vacuum.
Because of this, traditional blow off valves require super-soft springs just to open. The problem is that soft springs sometimes do not hold the valve shut under boost, which can sometimes lead to boost leaks during on and off throttle conditions.

The Turbosmart RacePort EM, paired with our custom plug-and-play BOV controller for B58/S58, solves this completely.

Instead of relying on engine vacuum, the controller keeps the valve fully shut at all timesand only opens it when electronically commanded. No spring compromise. No leak paths.

Result:

• Valve stays sealed under boost

• No bleed-off on partial throttle

• Precise, repeatable control

• Works on stock to heavily modified B58 setups

This is the most controlled and reliable blow off valve solution for the entire B58/S58 platform.
