    B1 wheel vs. C3 wheel?


    Does anyone know why its recommended and/or required that an after market ECU be used with a Riva B1 wheel whereas R&D has no such requirements for their C3 wheel. Arenít they essentially the same? Can I get by with using the B1 without an after market ECU.

    RD C3 = 10 psi @ 7700 RPM
    Riva B1 = 11.5 psi @ 7700 RPM

    Both will be on the boost limit without a RD Powershot or aftermarket ECU (You will not see the 10 or 11.5 psi)

    With the Powershot you will still not get all of the benefit of the wheel capabilities in the case of the B1. Unless, there is some secret that the Powershot allows more boost than advertised and documented by the vendor.

    Are there any realized gains with the B1 wheel without an after market ecu and/or powershot?

    Depending on you setup of other items such as impeller, cooling, intercooler, etc... you will see some gain, but you will always be cheating yourself out of some amount of PSI if the ECU is not addressed. If that is not going to be addressed you might as well get a RD C1 or stay stock.
