    That looks like a nice fat powerband!

    Was it a healthy one? Those usually do around 260-270whp from what I've seen. My M62B44NV (with your chip that works just fine BTW) put down 264whp and 296wtq, not on a Dynojet...

    Looking good man! Are you planning on draining the Provent to the pan or is it just capped at the moment? Looking forward to seeing what you come up with, working on another setup right now for a supercharged car.

    Currently have a smaller can to collect oil inside the bumper
    But am thinking of just draining back to the oil pan and forget it.
    But will still change to valve cover as the new source of crankcase vent

    I have the same oil/air seperator on my supercharged 540i/6. The dipstick was too hard to adapt a bung to so I tapped it directly to the sump using a 1/2" bsp thread. Used a 3 stage thread kit and used a 19mm drill. Easiest spot is on the side of the sump near the front on the RHS. You have enough room there to use a cordless drill to drill the initial hole. The good thing about te m60 is u only need to drop the lower part of the sump. The good bit is you get to check the oil pump bolts and chain tension. My pump bolts were pretty loose and the chain was very sloppy.


    Just started mine up yesterday (see the supercharger thread check in here). Runs really nice with the maf on the pressure side and the FMIC but I run into a hard stop at about 5500 instead of the 7000cutout on the ecu. If it runs out of maf range does it just stop?

    Maxed out maf may throw a fault code, but will usually just lean out. The DME no longer sees more airflow, and starts injecting the same amount of fuel for the rest of the rpm. That is bad with a blower, since you have more boost the higher your rev it up.

    I don't think it's the maf. We tried a few and with a new oem one it still does it. By the seat of the pants it doesn't feel lean or no pinging.
    Its like a hard cut almost like a electronic rev limiter. We swapped the ecu for another Bosch 404 and same occurred. We are going to replace the harmonic balancer as this could get a bad reading. I have a new crank angle sensor. It's consistantly about 5500. The ess chip is redlined to 7000. Could even be a currupted chip.

    The good side is power up to this point is orsome. Way stronger than before up to the low cutout. And with the air/air intercooler power is consistent. I'm going to plumb in a wideband with air fuel gauge and a boost gauge to see what's happening also.

    Bad cam/crank sensor can be at fault.
    I highly recommend a wideband AFR kit and Boost gauge on any boosted car, especially an older car or one that is converted from N/A to FI.

    Wideband , a/f gauge, boost gauge and mechanical fuel pressure gauge will go in next day or so. The ecu change made a slight difference to the cutout so we think it's now the maf running out of range. Pulled the fuel controller out of the e24 as it's laid up so we should be able to tune the fuel and the mechanic has a few tricks to sort the maf side. Have a Porsche 803 maf I can use if need be.

    Up to where the power falls out it goes as hard as hell compared to what it did before. Even with the air to air intercooler the pipework has more logical paths and we probably have more boost than we thought we would have. It's going to be orsome.

    What kind of bsfc numbers are you seeing at Max torque?
    Or possibly air mass flow rates at peak horse power?
    Also what kind kind of charge temps are you seeing pre and post IC?

    Not sure what happened to it in the end. It seemed to make good power. Not sure if dudmd sold it off. The m60 is a resilient engine. Not sure what the limits of the standard engine are. Pity this wasn’t delveloped a little more.

    Yeah I post a few comment on his Youtube channel to see what’s up with it but nothing. It seems his Sl65 didn’t put up good numbers like he wanted but it sound super nasty

    Often people are a little fixated on the dyno numbers their car makes. Just go out an enjoy it.
    My old v8 Ute with cammed L98 v8 makes nice power ok the dyno (410rwhp) but feels not as fast or enjoyable to drive as other cars with less power make. I guess with the GM v8 they are all mid range power so a little flat at low rpm and no ramp up at the top end.
