    i should really find a difference with the wheel riva and vt1100. Does anyone know an address to balance supercharger in europe?

    If by "bad" you are referring to those missing chunks, those are balancing cut outs. The wheel is balanced by removing material.

    Yes, the pictures show the traces of balancing. I think the wheel is already balanced and then the assembled supercharger is balanced and that's where it grinds the nut. When I said "bad" I was talking about performance level.

    You don’t get much out of a flash and intake. About 100rpm more over whatever rpm you where before. My 18 with a 13/18 was in the 8100rpm level normally in the summer and closer to 8300 in the color months. At least what we consider cool in Florida. But my 13/18 had a blade break off just while basically cruising. Last time I’ll use one of those. Making it home is more important.

    Sounds like you need to switch over to 13/16 to get close to your target RPM.

    You'll actually make more power with the lower pitch impeller. Chargers are like chicken or the egg, what came first ..well to make power with a charger you need to spin it higher but to spin it higher you need more power OR less load on the motor, lower pitch will reduce load on the motor allowing for higher RPM and more power.

    That vibration is normal that is what this wheel does. Back when the wheel came out i posted about this. Mine shook the hood of the ski. It is normal from this compressor.
