    Charger Wheel ID

    Can someone ID this wheel for me. I am transplanting this motor into my sportster. It has 42lb injectors and a Les Cooke retainers and 8650 ECU. It is an older wheel. It attaches to the shaft with a 15mm nut. The 17mm is too wide. It is a 127mm wheel.

    Looks like an original Riva Gen1...

    What's the diameter of the inlet? Do you have a picture of the inlet? If its untouched (still has double bevel) then its a gen1, if its got a 90 degree lip, then its an S3...

    The front cover is stock. The wheel was in a red 04 charger.

    If the front cover is also red, then its a Gen1 Wheel...They usually came with black front covers that were machined...

    And only +1 PSI over stock, so just over 8psi..

    Thanks for the help. Do you think I would have fueling issues if I swap it with an et 127 the the additional rpm's?

    Do you have a way to monitor the AFR's? I would to be sure before you install any wheel...

    You'll be gaining atleast 3-4psi of boost at those rpm's by going ET127 over that wheel...

    I would suggest swapping the 42's for 50's as a start, but monitor those AFR's right away...And look into a RRFPR also, to dial in WOT numbers...

    What 8650 ECU is it? Riva? Rotax?

    It is a Les Cooke. I think I will just leave it then. It has been reliable and is going into a boat anyway. Dont want to sink that much money into it. Thanks for all the help.
