    1-1 pulley kit

    A friend has the the full 1-1 pulley kit from R&D complete with injectors.
    He only gets 71mph...
    What could be the problem?
    Before the kit he was getting 69.
    He has the riva plate + 2degree wedge + riva air intake + riva exhaust(2007) + intercooler upgrade + cool air filter from R&D + pump cone.
    What could be wrong and he only gets 71?
    He got the afr gauge done everything but still top speed sux.
    Any help?

    From what I remember reading from skip, he said that you would see 2-3 mph with the 1 to 1 pulley kit. That sounds about right. Other are using the 1.05 to 1 and are seeing more. How noticeable is the extra power? I'm thinking about getting this kit soon.

    Extra power is noticeable but it aint worth it in my opinion.
    Too much money for very small gains.
    I was about to get one also but now i wont.
    The guy will give it another chance but he is about to take it out.
    Fuel consumption is terible.
    Supercharger whine got a lot louder.
    There is also a ratling sound at idle.
    I aint getting one.
    About the 1-1.05 a guy here has amazing results but Glen does not suggests it with pump gas.
    I could realy use some help from guys that have the kit and are satisfied.
    Maybe we did something wrong.

    I run the 1.05-1 pulley on 93 octane pump gas. Yes the charger is LOUD!! The fuel consumption is TERRIBLE. But I'm happy with the results...
