Sounds similiar to mine... 
I know when I first start mine up, it sucks, slurps and sounds loud as hell. My one friend was like damn that thing sounds like you have a some metal on metal going on... LOL but as soon as it warms up it quiets down. I mean its not stock quiet but just a tad louder and then under load it screams....VVVVVVV8888888888
