    Default Anyone like Injected Rats?

    This is a project I have been building for a year or so. The Kinsler EFI is run by a FAST ECU. Not a boat although the injection came from a Multi Motored CP Performance Offshore Race Boat. Running 500 ci Mercs. And it will be going into fiberglass It's been a steep curve learning the EFI programming. This intake was for a tall deck, it took about 8 hours of machining and tweaking to get it to line up nicely on my 9.8. Don at Motor Machine Super Shops handled that process. Horsepower By Gerolomy did all the head port work. The cam is a custom grind Comp that was designed by Phaff and used in a 510 ci motor that broke the billet crank hub. I got the flawless roller cam with only a few hours on it. So far I am into this about 9 grand. This may be a challenge getting the throttle resolution to a streetable operation as the injection has 2.9 butterflies. I do have a plan in place just in case this is an issue. The cool part is I can control fuel and timing on each cylinder, I think I can get this to perform way better than a carb motor. If all goes well cool, if not it will be a blast tweaking on this. In a week or so I will put in the car and start hooking up all the essentials.

    Yep I love that. There was a company a few years back that made a go at it, the injection. I wanted one pretty bad. I think idle air control was a little tricky on that kinsler style.

    I love them.
    I have never done the EFI stuff though. Just mechanical.

    I like that Corvette. I had a 65 fastback in 1973/74 when I was an 18 yr old kid. Do I ever wish I still had that car.

    I've got some experience on the FAST XFI units and could be of some programming help.
    To get some resolution on the throttle sometimes they use a cam shape on the end of the throttle shaft where the cable hooks in.

    I would think that the idle air control would not be possible to use because of no plenum area in the intake.

    One would think that but, Kinsler has worked that out via a common small plenum that ties all the ports together. This with the use of a MAP sensor should handle the task. This little plenum also smoothes out the pulse so you can get a good signal. It will work I have the faith and perseverance!!! And as usual I am building my own plenum Yes I love my 65 vert, we have been through so much together I may take you up on the offer as i move forward Thanks...Denis

    Looks great Denis. I plan on putting a setup just like that on our ski boat, so I may need to pick your brain in a year or so.

    That looks great. I saw clip on the nelson race engine website where they worked on Tim the tool man taylors truck. It was an efi stack setup that they dialed in for him.You may want to check it out.

    Haven't named him yet. It is already built and sitting. I have a mechanical injection system on it right now, but picked up a polished Kinsler EFI setup like yours. I figured being a ski boat I don't want the hassle of having other family members struggle with the In's and outs of the mechanical injection. I figured EFI should be "flip a switch and go".

    Nice Paul polished is a score, I never priced it to get it done. I was afraid to.

    So is your motor a tall deck?

    What ECU do you have?

    I don't have an ECU yet. I just have the manifold with the injectors and fuel rails. It is a standard deck 496 with a bunch of old parts we ran on our funnycar. I will see if I can get a picture of the injectors today. Here is what the engine looks like right now.

    You mentioned you had the same as mine….The reason I ask is my manifold was for a tall deck. As far as I know all these older offshore Kinslers fit tall decks. That’s all I found when looking was these. Or at least for the price I was willing to pay. I can certainly buy a 9.8 EFI for 10,000 grand +.

    These older EFI's seem to fetch around 2500 complete. The stock merc ECU is very limited and somewhat useless for most apps. I got lucky and got the FAST unit with all the sensors o2, MAP, TPS, Air temp, and harness. You can pick up a rebuilt Felpro Sequential ECU for around 400 without harness and sensors. The older Felpro's are much desired and is now called the FAST Classic. Lots of adjustability and dependability from these low cost units.

    Motor looks cool, get one up of the EFI!!
