no, not all turbo'd cars have blow-off valves
normally excess boost would be released thru the waste gate

your friends talon releases the pressurized air back into the air intake charge instead of in the atmosphere...

^^I hope you were joking....

Most factory turbo'd cars have a recirculating blow-off valve or by-pass valve. Instead of the air pressure in the charge pipe being expelled out into the atmosphere, it is sent back into the intake pipe before the turbo charger to be re compressed.

yes, it's a looping system to keep the MAF happy. you go and vent to atmosphere, not only are you breaking emissions laws, you're also making your car run pig rich.

on those they meter how much air is put into engine venting soem of the air off makes it run rich cause it adds fuel for that missing air hense rich. Unless he has a 2g the 1g bov 90-94 model year is more than good. you don't need a aftermarket one. in order for you to vent the bov to get that pssshhtt sound you need a gm maft blow thru setup www.dsmtalk.com is your friend. Do not touch anything on that car untill you read up on it. ps bov on talons is on the pipe going to throttle body on teh underside near battery
