    Default Crower style stack injection MFI

    I bought a Crower MFI set up that was listed as being complete, minus hoses, set up for alcohol, completely rebuilt by Kinsler (except the Crower mechanical fuel pump). It also came with a couple of books/catalogs from Kinsler.

    Problem's. One problem is that in the books there isn't a plumbing schematic that shows all of the parts that I have. I don't even know if I need all of the parts that I have. A couple of the parts I don't know what they are. I saw a flathead Ford powered altered at the Antique Drags the other day and that flathead didn't have near the components in his Hilborn MFI that I have, so why do I need them? I don't know what fuel he was running. Another problem, typical for me, is I can't make up my mind on what fuel to run. Avgas, E85, 110, and alcohol are all under consideration. Oh yea, 13:1 468 BBC, tunnel jet drive.

    I've got countless numbers of people telling me that I am going to have nothing but problems with this set up and that it will never run correctly. ALL of the people that have said that to me have never owned a MFI.

    I've gotten a few people to PM/call me and tell me that once it's dialed in I will be very happy with it. ALL of the people that have said that to me have owned MFI stack systems.

    Anywho, here's some pics. The first pic is of my MFI, just so we're on the same page. Second pic is a Kinsler drawing of a old method of plumbing a MFI. Third pic is of a "new" preferred method of plumbing a MFI. Fourth pic is of a plumbing schematic for a Vapor Sepearator Tank that I have. Last pic is plumbing schematic for a Jet Selector Switch that I have.

    More pics and questions to follow. Hopefully the pics work and aren't too big.

    First off, I can tell you this..... I don't know shit about MFI (surprise) but I've had two friends run them and then remove them after fighting with them for two or three year's. With both guy's there were big changes with the system's from a 90* morning to a 110-112* degree afternoon. Just to much for them to fight with.

    Since you are in El Cajon call or go see Greg at Total Performance on Prospect in Santee 619-562-9894. Both Greg and Mike there have had experience with the system's and should be able to help. I'd be surprised if they can't.

    First pic. I'm calling this part a fuel log. Why does it have two ports and what are they for? Which port is which? (Edit: Part is called a barell valve, port pointing straight up is inlet, port pointing away from distributor on a BBC is outlet)

    Second and third pics. My Crower F1 mechanical fuel pump.

    Fourth and fith pics. Jet Selector Switch.

    The "dial-a-jet" will or should help a lot. What size engine do you plan on putting this on ?

    Sorry about that 468.....Hummmmm

    Next up is a Secondary Jet Valve.

    Next two pics are of my Vapor Separator Tank. You can see and read the tag on it, it says something along the lines of "this top most outlet..." well that isn't wired to the top most outlet, so is it a typo or is it tagged on the incorrect port?

    Lastly is some pics of the two parts that I don't know what they are or what they're for. I'm guessing one of them is a filter for gasoline use but that is definately a guess.

    The first three pics are of the same part.

    So I'm also guessing that the more parts that I use the more "tuneable" it will be. Instruction book is thick which isn't helping me at all, but if I wanted simple I guess I should have put my cash into a more common system, like a Dominator or something.

    I know there are a few on here that have successfully run this type of system. I need some feedback from you guys, please.

    The first three pics looks like a pressure regulator..The other is a filter..

    I saw a gloss back jet boat out at El Cap one evening, tunnel hull with red or purple trim on the engine and everything else all black, running an MFI. It sounded real good. He was with a couple of other "heavy hitting" looking boats also. I know I've seen a pic of that gloss black boat on this forum but I haven't been able to find it since I first saw it. I'd love to pic that guys brain or crawl all over his boat, or both.

    Man, I wish I could help you, but like sleeper, I don't know crap about MFI. That said, they were (are?) real popular with sprint cars and also with UBGH back in the day. My buddies that ran them on sprint cars (alcohol) would mess with the pill (tank return flow) regularly, but they seemed to always work great.
    Also MFI is very popular in asphalt drag racing... Mostly the Ron's system (Toilets) but it's the same basic design, so I think they can be worked out to be decent.
    OBTW, the Crower "calliopie style look VERY cool IMHO. I don't have the patience to work through it, but best of luck to you.

    Look in the catalog and there might be a page in the front of the book....that tells what the system was set up for. Cubic inch, etc. There may be a "number" assigned to this system.
    The pump is an Enderle 80A....not a "Crower".
    This is not a conventional (as in simple) plumbed system. You need to get hold of Kinsler and see if they can identify the system. They keep very good records.
