From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.


The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.


For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

    Thanks for the info.. haven't actually got the injectors yet so ill definitely address that

    No its fine.. the belt is an inch or so wide, the idler pulleys are about 2.5in wide.

    Jspec- basically the same question everyone else has asked.
    mounting the SC up higher the exhaust header is in the way of the intake. Also the AC location has 4 perfectly flat bosses to mount the SC bracket. Quite simply it is the easiest way

    what about the opposite positioning? ie the alternator wayyyy down low and the sc up a bit higher on the top ac bolts and original alt bolts?

    Merely speculation/suggestion. Just trying to help you get the most out of what seems to already be a very well thought out and definitely unique setup.

    you make a good point. I don't claim that my set up is the best one ever, as it isnt being manufactured (yet lol jk) However I am the only one doing it, maybe for good reason haha. Ive put alot of thought into it, and am trying to be somewhat simple in my approach. Making as many parts myself and outsourcing as little as possible.

    I am open to suggestions, of course, but at this point I am finishing up final details before initial start up and tune. It would be running already but im waiting on my oil restrictor from vortec. I didnt wanna send 60psi into it even for a second.

    Well, relocating the alternator to the power steering part of the crank, while a bit more difficult, essentially just underdrives the alternator just the same as any aftermarket lightened/underdrive pulleys. While it would underdrive the alternator (which doesn't seem to be a big deal to the thousands of people using such pulleys), in theory, it would net you more power since underdriving your accessories puts less of a strain on the crank.

    For some reason I have it in my head that you could just put the input pulley of the shaft in front of all the accessories and just use a belt that is ribbed on both sides. This would give you more than half the pulley touching the SC, which is very good IMO. You would already have to do so much custom fabrication as it is for that type of setup that positioning is entirely at your discretion. Why I am still harping on such an inefficient setup? I have no clue.

    Back to your build. Looking at your pictures, it seems as though belt to pulley contact on the SC is 1/3 at best. Will it work? Yes, but from experience with the Stillen supercharger kits on the Z's and just belts in general, you usually want at least half the pulley contacting the belt for ideal/efficient transfer of the power from the crank. Is it possible to run the SC belt from the old power steering belt or vice-versa with the alternator being driven by the old power steering slot on the crank? Just my thoughts on the matter.
    ok.. so that picture is before I made changes to the belt routing, I am using close to 3/4 of the supercharger pulley now. I was just to show how much space the SC really takes up. A double ribbed belt isnt really needed. Now if the supercharger spun clockwise (as some do) then a double ribbed would be a necessity to correct the direction of spin.

    Running the supercharger off the power steering belt would be possible if you can get a pulley small enough on the SC. The difference in diameters is how you get your boost. You would need approx 2.5in (I forget if the PS pulley is 3in diameter or 4in) for 10psi, and even smaller if you wanted more boost, it was part of my initial thought but the desire to up the boost later overturned that idea.

    Or vise versa, running the alternator off of the power steering pulley would work, but would that affect the output of the alternator? Since it wont be spinning as fast on the smaller pulley. Also that would mean pushing the alternator out that much farther from the engine. I made the alternator tensioner (slot) as part of the SC pulley, so they bolt together for added strength of the set up.


    pphheww long winded sorry.

    so true... I dont drive the car much. nice days, no rain, no snow. A 4pt harness with 3in shoulder straps suck for daily driving lol

    there is no vise versa. you cant keep power steering or AC. Unless you cut a big hole in your hood for the SC to stick out. Seriously, the SC is not small, it takes up all the room previously occupied by the alternator and AC compressor.

    SORRY THIS PIC WILL MAKE YOU DIZZY AS F*CK

    I thought about that yesterday, it would be quite easy for me to put together a kit of brackets n such, let the buyer pick their own supercharger unit. Anyway, just a thought. The SC does not fit in the power steering location because the air intake sits too close to the exhaust header, unless you want to cut a big Hole in your Hood lol. So unfortunately AC and power steering cannot be kept with my setup. Which doesn't matter to me. Vortech Made a kit for the 97-99 civic B16, using a jackshaft to locate the charger next to the distributer, retaining AC/PS, but has been discontinued.
