Turbosmart EFR Bypass Valve Replacement TS-023-1261

I replaced the EFR internal bypass valve with the Turbosmart Kompact Shortie - Plumb Back TS-0203-1261.

First thing i noticed was how much better it is made than the simple spring and un-reinforced diaphragm, it is a piston type arrangement and you need to apply a fair bit of force to open.

The Turbosmart internal BOV vents back internally but you can get one that vents to external however i didn't want to have that.

After installing and running in the shed it seems to be all ok, need to get out onto the track and see if it has worked now.
