    Blower intake

    I need some advice please, I have a 4 71 blower that I want to put on a RV8.
    I have a Offenhouser inlet that I could get converted but was thinking, would it be feasible to make a intake to bolt to the manifold.
    Can't think why it would be a problem but can anyone let me know any reason not to.

    Thanks,
    Iggy.

    I,m doing just that with a wade ro34, my blower bottom plate is made to bolt down in place of the carb.... however there are a few things to look into.... on mine the lower plate has studs and as the manifold is drilled direct i,m useing an alloy 2" carb spacer so i can have studs for this plus the blower studs the other way, the other thing is the offenhauser has a 5 degree angle on it,s carb mounting face and not alot of alloy to mill flat but you could use an 5 degree wedge plate that holley sell so bringing your blower back level with your crank, or spread the milling and take two and a half degrees of the manifold and two and a half of the spacer,

    Thanks for that, pretty much what I wanted to hear, I was thinking of using 1" plate and chamfer down from the blower exit to the inlet manifold, the spacer could also be used to mount the pop off valve.

    Yup i,m putting the valve in the spacer and i,m going the wedge plate route but again going alloy and welding this to the spacer so i have one less gasket to worry about plus adding meat to take the blower,s weight, a good alloy front plate to take the snout bearing will stop any rocking and stress on the blower / spacer mount.

    Good advice, much appreciated.
    Do you know of anyone who can make snouts, looking at the blower resting on the engine, I don't think I'll be able to get one off the shelf.
