Get a DEI 528T pulse timer relay. You can adjust the time to your needs. Or you can get a Pac-Audio TR-7 gives you the same thing with more options. You can find these on ebay.

Just Put a Smaller Capacitor and you have it.

Try 100uF Also Almost Any Transistor that will pull a relay will work.

i have a question also do they make a 5 or 6 minute relay? i installed a friend keyless to his air ride on his truck and i was thinking of hooking his air compressor to a timer relay to cut the air on and the pressure switch will automatically cut it off....
thanx
