    Boggers Chevy corvair project

    Hey guys,

    I Know its not a mini but it won't be a big block rig eather.. I got a 110 hp covair motor and I was going to start the rebuid on it and keep you guys posted. What to you think? Will you still except me? Or am I an out cast now.
    Let me know if you guys want to see some pictures of the vair reserection.

    Bogger,

    The very first airboat that I was ever around (when I was still a little kid), was Corvair powered, with a homemade belt reduction. This was way back when Corvairs where still in production. I'm getting OLD.

    I don't remember a lot of details about it, but it was probably "about" a 2:1 reduction. The engine was mounted very low in the hull, had all of the original cooling sheet metal, fan, etc., and had a LONG belt drive, consisting of (I think) 4 v-belts.

    You'd probably be able to do a much nicer job than that one was. (I've seen your work).

    I say go for it. It'd be like a 4A084 on steroids.

    The 4A084 is not technically a Mini either, but who really cares?

    I'd love to see pictures of your Corvair resurrection.

    Thanks,

    Duane

    Hey Bogger,

    I'd say go for it, I for one won't consider you an outcast, just a bit different. Things would get really dull if we built the same boats over and over.

    As a matter of fact my Aircat 084 had a corvair on it before I got ahold of it. I wish it still had a corvair on it, (Thats from a Ford guy!) Also I'm building (soon), a Tomcat with an 1835 VW.

    I would love to see your build pictures, keep 'em coming.

    Thanks for the input everyone.
    Here are a couple pictures of the start of the reserection. It aint pritty.
    The motor is a 110 HP high out put RH block with 110 heads.
    Acording to the plane guys when put it together right it can produce 120 ponies at 200 ft. pounds of torque.
    It will be a long process since this motor has been out in the weather at a bone yard for 30 years or so.
    I took the skins off it last night, and started to pull the heads and broke 5 of the twelve head studs on the first side, which were mostly rusted through. Boy am I having fun.
    Thanks bogger

    Yeah Bogger, it does look a little rough.

    I don't know if it was rode hard, but it sure looks like it was put up wet.

    At least it seems to be mostly all there.

    When you get done with it, it'll be a beast, I'm sure.

    Keep us posted.

    Thanks,

    N4WSP,

    The 1.6L 90 HP Aluminum Geo would be a heck of a HP upgrade from a 4A084, for sure. And I'd guess that it'd still be a gas sipper compared to some.

    Do you have weight info on a fully fitted out engine, with the reduction, radiator, etc.?

    Thanks,

    Duane

    That looks sweet!
    Is that a blower or a reduction unit on it?

    n4wsp,

    I checked out their website, http://www.raven-rotor.com/ and they do have some neat ideas for the GEO / Susuki engines.

    Nice stuff ! I don't need it right now, but will bookmark it for future reference.

    Thanks,

    Duane

    Steve, that is the motor that is in my Tracker. I thought about using it but I'm having so much fun with the Tracker hate to put it down. The darned 084 is just too reliable and easy to work on I ate to change anything.

    Bogger,

    I've rebuilt some ratty engines in my day, but they were immaculate compared to yours. When you get it up and running I think you'll deserve a gold star for sure.

    Bogger,

    Shazam !

    Rough does not begin to describe it. I know that some people thrive off of a challenge, and I think that probably describes you, but you are definitely more motivated than I am to take that on.

    I sure as heck wish you the best with it, though.

    If you're able to bring it back to life, it'll be a true gem, but you've bit off a VERY large chaw there.

    When (if?) you get it going, I'll personally send you a gold star.

    Please keep us posted.

    Thanks,

    Duane
