    Hey John- I'm hoping you can shoot me some advice.. I have a mini s convt r52 2007. There is a drip coming form the oil filter housing. Cleaned everything, dried everything, runs for 10 minutes, I get a slooow drip from the bolt facing driver wheel. Your post was only 1 of FEW about changing filter housing gasket. Its a huge job not to replace entire housing? If its warped, I have gone through a lot of work for not. Yes changed oil, new seal. I live on an island so getting what I need is tricky, expensive.. Measure twice cut once.. Any suggestions you can spare would be amazing. Just gasket? The entire housing? Thanks in advance- kristin

    yes I got your response in PM. Thanks.
    I am just concerned that the reason for such low AF ratio (rich) readings is beacause I am running out of fueling at high boost, high gear and that the water/meth is just masking the problem by dropping the AF into the high 10's.
    Everything I have read says that I should be running out of fueling with a stock WUR like I am using so this big dive to rich conditions has me wondering. I am afraid to turn the unit off to see what I get for AF ratio with just the WUR to verify my theory, as i dont want to detonate my expensive build.
    Any thoughts on this?

    Hi,
    I wanted to ask what pressure settings you found worked for you water/meth injection? Also how you determined what pressures to set at while tuning it.
    I just installed a Snow performance kit in my 79 930 turbo and am tuning it now, but still not satisfied at high gear high boost.
    I have a 3.4 liter with SC cams and Euro fuel head and injectors and ported intakes to 36mm.
    Running a k27S turbo and headers, with B&B intercooler. What I am seeing is AF ratio dropping to 11.0 and even 10.9 to 1 in 4th gear at 0.75Bar boost and then the car seems to hesitate a little. Its very subtle and only does it on long pulls at boost in the higher gears.
    I have the injection starting at .5bar and max flow set for full on the controller which I am told is between 19-23psi .
    Question: What should I do to tune out the rich AF at high extended boost, but not jeapordize running lean at mid boost levels before the mist starts pumping?
    Any tips or advice in tuning this thing?
    Thanks,
    Fred
