    :facepalm:I’m adding this info for the last step after the supercharger is rebuilt.

    When I have taken my supercharger off I don’t disconnect the battery.
    No real need too for me.

    You need to do a ECU reset after your rebuilt if you didn’t disconnect the battery.

    I did a free power upgrade yesterday,

    I reset the ECU by disconnecting the battery for 20 minutes.

    I have done this before but not for 20 minutes and apparently the ram was actually never cleared because my scanguage was working after I did the reset before.

    This time I disconnected the battery and came back probably 20 minutes later busy doing other stuff and reconnected the battery and the scanguage turned on but had no info displayed.Mmmm,

    Apparently the scanguage will not display any info while the ECU is in the learning curve.

    It took 75 miles of driving and then the scanguage was working again which let me know the ECU was completed.

    Truck now is getting 21 degrees in timing on full throttle where is was at only 18 degrees before just from a correct ECU reset. A bunch of new power!

    Apparently I wasn’t clearing the ram before with the battery disconnected for 5 minutes

    So if mine is whining fairly loud do I not need to do a full rebuild? Maybe just change the oil?

    Does anyone know if this part changeable? It’s for 3.4 4 runner. I bought it and it was bent like that. I’m afraid if I try to bring back in it’s place it will break. Any ideas?

    Those two lines are vacuum I believe, the tubes are probably pressure fit in there.
    The exposed end is probably the same as the end going into the supercharger.
    So you probably can match something up without to much trouble. I seriously doubt this part is available anymore for the 1st gen.
    1) So you might be able to back it out and find something similar.
    2) Or cut it off, then drill out the old part if it doesn’t come out, and install a new one,
    Jb weld it in place if needed.
    3) heat up the tube and bend it very slowly to the correct position

    I got the O-Rings but I don't see the gasket on their site or anywhere else I've looked. In your experience what kind of performance impact is it with the leak at the bypass? Both HP and Mileage? Mine is leaking bad enough it won't idle below 1500 RPM when warm and when I coast to a stop and put the clutch in the RPM's drop to around 800, then revs back up for about 2-3 cycles before resuming it's 1500 RPM idle.

    There are two O ring gaskets different size only, you will loose boost and have idle issues,
    No gasket for the lower bypass part. Just get a tube of high temp gasket maker.
    If you have ANY VACUUM leaks, superchargers will not run correctly and engine too. You can use this gasket maker alone with both the O rings together for a better fit.
    Remember if you install the top ring in particular and you decide to pull the
    bypass tube out you probably will destroy the ring, it fits in a grove and will probably rip or get gouged if you pull it apart again. The gasket maker will
    help make sure these sections are tight and not loose and sealed tight.

    Great, I thought about doing this but figured if there was a gasket I should do it right and didn't want to tear it apart to look unless I had what I need. Good info on adding some to the O-Ring area too.

    Thanks!

    Just finishing up my supercharger rebuild and can’t remember what it was like when I took it apart. Is the nose cone shaft pushed in far enough? When pressing it, felt like it bottomed out. But now installing the pulley any it seems like I need to push it in another 1/2”. Is the little cut/grove supposed to line up? And how much of a gap is needed between pulley and s/c housing?
    Here are a few pictures:

    My gap between the housing and pulley is about the same or less. The only way the pulley lines up
    is with the key in the shaft. The lines in the pulley are for air only and better grip

    If you torque down the nut the pulley should not hit the housing

    Thought I would add this here for all the supercharger guys as you should have an AFR and Boost guage if your running a supercharger.

    This is the coolest gauge!!!! I just upgraded to this Gauge.

    https://www.innovatemotorsports.com/products/psb1.php

    First of all it’s actually a boost gauge and an AFR Gauge in one, so one pillar pod is all you need.

    This gauge has the option to set as a boost gauge only or an AFR Gauge only.

    You also have the option of have both gauges showing at the same time with the larger display as your choice of being the AFR or the boost.

    You can toggle either gauge at any time to have either boost or AFR as your leading gauge.

    It also shows the vacuum as part of the boost gauge.


    It also has a button setting that shows the top boost pressure you have run. This clears each time
    you turn the motor off.

    It also has a warning display that says “02 CUT”

    This display pops up on the top right corner whenever the AFR is out of its safe zone running lean.

    The gauge also let’s you set the AFR warnings limits.

    So let’s say you set the warning “02 cut” at 13.4 and the AFR UNDER BOOST goes over the lean number of 13.5 or higher it will give you the warning “02 CUT” display so you know something is wrong with your setup, (running lean).

    The gauge works fantastic!

    The failsafe will not actually cut the boost because our trucks are an older design, for a newer truck
    the gauge when it goes into the “02 CUT” (lean area) it would actually stop the boost from going higher.

    It also has a light is the guage that tells you when to shift, but that part doesn’t work on our older trucks.


    So now I will always know what’s going on with my AFR and boost at all times.

    The AFR should be in the 12 range under full boost and 14-15 at idle.

    That’s how I’ve done mine Sean, one will fall out into the manifold tube and the other will come out through the back of the SC. There are some black SC that have the back sealed and unfortunately you have to pull the bearing out, but press it.


    Just make sure you are careful with the barb in the back when pressing. I forgot about protecting it one time and snapped it off. Had to get it removed and a new one installed. Not the end of the world, but delayed my rebuild a day or so.

    Installed my supercharger today and it’s running really lean. Coming up with a po306 code. I’m hoping the new urd fuel pump will fix this issue. Anyone else have this happen?

    Mine ran way lean but didn't throw a code, the supercharger itself shouldn't trigger any codes unless there was an issue with the install (vacuum leak for example). Should not need a stronger fuel pump unless you are adding another 7th injector or smaller pulley, the stock pump can handle the supercharger normally.

    A PO306 code is a misfire code I think? I don't have any experience with it myself. Did you install the 2 step cooler spark plugs with the supercharger?

    I’m running a 2.2 pulley with bigger injectors. And at this point I need to also have a bigger fuel pump to keep up with the boost and the injectors.
    The po306 is a misfire code. I looked over my vacuum lines and it all looks correct.

    Looks to me you are missing the extra long bolt that holds the S/C to the manifold. That can't be helping.
    Also there is a port for an EGR vacuum right behind the T.B flange on the S/C back side. I neglected to plug this port during my S/C install and was getting a lean error code.

    That's exactly how I got my lean code when I bought the truck (supercharger installed by PO). Found the EGR port unplugged on the back. But the lean code I was getting was a P0171, weird that the OP is getting a misfire code. Makes me wonder if something went awry with the spark plug install or wires? Not really sure

    Yes there is a bolt missing. I ordered on online and it should be here in a few days. Also that vacuum line is plugged in. I triple checked to make sure.
    My code reader doesn't give a lean code, it only comes up with the miss fire.

    I did install new sparkplugs, gapped them all at .032. not sure if it makes a difference but the ones I used have 3 prongs.
    But I'm thinking if I have a 2.2 pulley, 305cc injectors and haven't yet installed the urd fuel pump. wouldn't that technically make sense that not enough fuel is getting pushed threw?

    From what I gather, a P0306 code is specific only to a cylinder 6 misfire and is most commonly caused by either faulty spark plug, faulty spark plug wire, distributor failure or faulty fuel injector. I have read that low fuel pressure can cause it as well but I would think if the fuel pump were causing low fuel pressure, wouldn't it trigger a misfire code across all the cylinders or more than one at least? I honestly can't say for sure, just speculating.

    If you didn't have this code prior to installing the supercharger then it's fair to say that its related to that or the install itself...so would be hard to believe it's a bad injector. That's why I personally lean toward the spark plug or wire since those had to be changed out when installing the blower.

    This is just my novice interpretation of it but hopefully someone with some actual experience with this code can chime in for you
