O2 Sensor on Pressurized Side of Manifold
 

Is having the 02 sensor on the pressurized side going to hurt it? Or should I plug the hole in my HF manifold and relocate it to my Downpipe w/ a bung?

put it wherever you want imo. plus, i've never heard anyone call it the "pressurised side"

Well seeing as a turbo spools due the the pressure difference across the turbine the manifold is consider the pressurized side and the dp should (in a perfect world) have no pressure.

any part of the exhaust always has pressure the way i see it...the engine is forcing the air out. back to the poitn, ive used and seen people use the sensors anywhere pretty much with no problems

Yes the exhaust does have pressure but the manifold sees more. If you boosting 8psi and your exhaust has and Inefficeintcy of 2 psi your manifold has apprx. 10psi in it. Good old math!! But Looking at the pix I see most guy mount it in the manifold for symplicity. and I'm gonna need the space on my DP for the Wideband.

Thanks anyways

The turbo is spun by HEAT energy...not pressure.

yep. no pressure.

anybody got pic of this pressure side?

How about filling that manifold spot with an EGT probe and welding a bung somewhere else on the DP for the wideband?
