i dont know wats wrong

i just put in a td05 turbo in my 97 eclipse gst. and everytime i boost over 5 pounds a horn goes off and i dont know wat it could be. can someone tell me wats going on? i also installed a greddy type r blow off valve with piping and intercooler with the turbo.

probably a boost leak but im not sure what you mean by "a horn goes off"

lol. thats funny. thats your bov.

{edit} i was drunk when i wrote that sorry.

everytime he goes over 5 psi? bov would only be when he lets off the gas with boost built up

im sorry but , this is some funny Sh*t!

i can just picture it....
vroooooooom, beeeeep!
only of this were true and it wasent your bov...

i know its not my blow off valve cuz wen i first put on the turbo everything was fine, but after 2-3 days of driving a loud horn goes off wen i boost above 4 pounds.

Is it your actual car horn? If it is there has to be a short somewhere. Disconnect/reconnect your horn, physically (should be located on radiator wall or around there somewhere.
