Is it needed to have a turbo on a car to install a blow off

Is it needed to have a turbo on a car to install a blow off valve?
i'm thinking of put a blow off valve on my eclipse01 with no turbo

there's no point in having a blow off valve for a non turbo engine.

A blow off valve lets the high pressure from the turbo to escape when you close the throttle to prevent the turbo compressor from stalling and blowing off your air filter.

In a non turbo engine, the valve could just stay closed.

why....it will not function

go ahead.i hope you learn something about cars while you do it. heres a tip.the engine is under the hood
