  1. General: I have no dog in this fight, but there are lots...

    I have no dog in this fight, but there are lots of holes on engine #1 story. engine #2 I'll agree as I've seen the same stuff.
  2. It's all dependent on how much power the cylinder...

    It's all dependent on how much power the cylinder is making.
    There's a formula for it based on bore size and use.
    How you set up the ring gap configuration on the piston is also important.
    You...

    well, I dont know his exact issue, but walking through logic, if cam torque is increased due to high pressure valvetrain, the vanos cant adjust as quick and causes plausibility issues
  4. N54: It's not the "part" but the issue of valve float...

    It's not the "part" but the issue of valve float is what Andy is referring to.
    Most people won't have this issue- not many are making big power, and well... most don't pay attention to valve seat...

    so...... sounds like past a smoke test they didn't know how to diagnose it......
  6. N54: I agree, only specific cars seem to have issues...

    I agree, only specific cars seem to have issues with it. Perhaps it's out-running the system's volume? IDK- just trying to figure out if that's a situation or not.

    you need vacuum in the intake, obviously :D
    But the crank case? for this experiment, no. PCV is obviously best when at idle and cruising, but to see if the crank case is pressurizing we need to make...

    I'm pretty positive (excuse the pun) that you're getting excessive crank case pressure and its pushing oil out of the turbo. We have seen a few people run plugged heads on the RB external system and...

    well...... what do you think closing the gap does? smaller spark, less efficiency.
    put a PR coil kit on there, and let em run wiiiiide open :D
  11. N54: nah. Run it.

    nah. Run it.

    Send me the trans, ill get'er done.
    I'm not sure if you can pull the tail off and do that, more than likely the shaft length is different

    All gone- haven't reordered.
    High lift cams will need valvetrain and piston/valve relief.

    Pure stg2, FBO, PI, etc.etc.

    It's much bigger now. Bigboost, more fuel, more PI, built trans, fully built engine, Ported head, aftermarket valvetrain we came up with, etc.etc.etc.
  16. N55: The pistons, is the first place to start.

    The pistons, is the first place to start.

    I agree- what i was saying is the snake would be eating its tail if you didnt have software to control it w/ limiters.
  18. N54: unless the table is adjusted, if the vanos...

    unless the table is adjusted, if the vanos doesn't go to the specified position, it'll toss a fault and limp home mode.
    A limiter may work, but if tables can be adjusted accordingly, then it...

    Gut two Vanos gears, set up cam degree wheels on both and on crank, and measure em.

    It took me about 2 weeks of fiddling to see what I needed to see lol
  20. N54: high lift cams will contact stock pistons, from...

    high lift cams will contact stock pistons, from what we've measured.
    We need to know if high lift cams are to be used before building the bottom end- we end up having to fly cut the pistons to...

    Maybe the vacuum pump vane is sticking or something. next time it does this check to see if there is vacuum at the booster plug in thingie near the oil filter.

    Stg1 and 2, no.
    I have our Stg3 with our valvetrain in it-
    Notice stock exhaust head starts stacking up at max lift. This is a big issue.
    After porting, it doesn't have the restriction.
