    Hooked up a wideband o2 sensor on stock ECU and boost.

    When cold the ski runs 11.6......after running the ski "Hot" for a extended wide open run it goes to 12 even.... this is wide open numbers.

    5k rpm I was seeing 12.5.....thats where ski like to run when not running hard.



    Are these numbers right? or do I need to do a free air cal?

    should have done a free air cal before you installed. AFR's will change depends on boost.... You dont want to run lean on higher boost,no boost or in vacuum ok to run leaner.

    why not the C3? Might as well, if your worried about to mush boost just adjust RPM's with prop... Im around 8000 rpms with 11psi. I could adjust prop to get more and prob will but I dont want to go over 8500rpms. Had them set my R3 rev limit to 8500.

    worried about supercharger clutch failure....I think I can easily see 80mph with those mods......

    What ski? Invest in BOV and S/C shaft, If you worry about things breaking I would not mod at all. Im really not worried about it,if it breaks i'll fix it. I going to get the R/D S/C super clutch just because anything will help. Couple more pounds of boost not going to hurt,just my thinking. Like I said its there if you need want it and you wont regret not getting it.
