    If Im not mistaken the mini rude has a spacer plate between the 2 halfs of the SCer housing. The 2 Rude doesnt.

    Other then that you can split the housing and measure the wheel. Mini = 137mm 2Rude = 140mm diameter

    Correct,The Mini Rude will have a silver spacer plate between the two halves of the housings....If the charger is apart,then as the boys stated,the Mini is a 137mm wheel and the 2 is a 140mm wheel...

    Well I don't have the spacer plate, so it must be a Rude 2. Does 13 lbs of boost at 8400 rpm sound right? Duke says I am down in power, he pitched a prop for me and rebuilt the charger. When I put the prop and charger on I could only get 7800 rpm with a 81 mm ring. I put a 83 mm ring on and got 8000-8100. Duke said it should have run 8500+ with the pitch he put in it, so I sent him back the prop, he re-pitched it and now I am at 8400-8450, he said it should be spinning more than that. I have checked cam timing, leak down test, compression test, Inncooler temps. Any ideas guys? Engine starts and runs great pulls pretty hard to, just trying to figure out why I am not running enough rpms.

    That's a 2Rude without the spacer. These are the boost numbers per the site..... Good luck Bro!

    15.5 PSI boost at 8700 RPM

    14.5 PSI boost at 8500 RPM

    13.5 PSI boost at 8100 RPM

    Perhaps it's just a slipping supercharger clutch.
