A/F Ratios & WBEGO's

We are attempting to make an educated guess as to whether wide band exhaust gas oxygen sensors (WBEGO's for short) could possibly be applied to blown (screw or roots) drag race methanol applications.

WEGO technology is quite familiar to us, and we know the precautionary issues related to wet fuel, shock, temp, response latency, etc.

What we don't have a good feel for is, what are the typical real world calculated (or estimated) A/F ratios for modern blown meth engines at idle, stage, and down track. TAFC or TAD or even Pro Mod.

Just trying to make sense of whether the range of the current crop of WBEGO sensors could possibly be applied to such applications.

Any feedback would be appreciated.
