    I'm thinking not very practical for the street but MAYBE somebody's done it? they block the water outlets, don't they? anything is possible!

    There's a guy on tbucketeers.com that did it.
     
  4. Wasn't there a Street Rodder or maybe Rod & Custom editor that was building a Model A roadster and planning a Potvin setup? Can't remember who...

    Other than the length and the engineering required to for a cooling system that works, why would it be any less practical than any other blower? I don't know if they are less efficient because of the length of the air travel, but they sure look cool in the right project. I can see a track nose t...

    Only problem is being stuck with 1 to 1 drive ratio.

    I think a blower could be mounted Potvin style and gear or chain driven to get a different ratio. Any reason why that wouldn't work?

    With today's gearbox as someone s
    d for industrial setup or chain drive,I would think it shouldn't be to hard else stated

    I had a potivin style Italmcanica blower for a flathead. It was chain driven.

    A car showed up at PBA last year in Meridan, CT. with one in front of a SBC..Had some type of blow through fuel injection [mounted at the heads] and was very throttle responsive as he was demonstrating it pretty hard..All fabbed car with aluminum skin over tube frame/roll cage...Of course no camera and too stupid to remember that my phone would have worked..duh..

    That car was handbuilt by Andrew Murray, whos is a very talented fabricator. He built the the whole car, including the blower set up

    I have a flathead with a 3-71 crank mounted I'm building. There are no belts to drive the generator/waterpump/fan so you are forced to run an alternator off rear end/electric fan/electric water pump which bring it out of HAMB territory. That is why I have never posted pictures of mine. The one that uncommon engineering builds has belts but in my opinion doesn't look at all like the original and still needs an electric fan. All of the street driven ones I have are EFI as well.

    Somebody made a gear box that went between the blower and the engine and you could change gear ratios. It used the same gears as a model A quick change. (narrow 6 spline) I saw it in the late 50's.
     
  21. If its the guy in Tx. he didnt leave it on very long, went back to blower on top if I remember right.

    I'm the guy in TX, but now in MN. Have swapped the Potvin/EFI and the B&M/carb inductions several times when I get bored. Potvin is running great with FAST EZ-EFI. Just did 600 miles round trip to T-bucket Nats in Green Bay, WI.
    Any questions re Potvin on street I can answer.

    Pretty sure this is the car. I saw it a few years ago at BTT50's and you're right, it's cool even though it is O/T. The front-drive Potvin blower was about the first thing I noticed. Hood was closed so have no idea how it was set it up but they must have made it work....

    The Potvin is just a 671 blower. The tricks are getting the fuel into the engine (the oldtimers used mechanic fuel injection or carbs on the blower intake), and finding places for the radiator, water pump and alternator. I use port EFI so only air goes thru the blower, the radiator and an electric water pump are in the back, and the alternator runs off the driveshaft under the car. Other than the crummy EFI available 20 years ago, it was not too hard.
