Release value sound on NA
hello
i'm about to buy a 1988 Porsche 944 NA
i was test driving it
and as i stopped at an intersection, i heard something like a release value for a turbo
sound like my friends Talon AWD Turbo
same sound as the air being released from a turbo
the seller says the car is nonturbo
i checked the engine, didn't look to be a turbo, but wat do i know
any ideas?
is this normal?
thanks
