yes, yes, my exhaust mani is comin off this week, i have a couple unrelated questions.

1. what is the minimum psi a open venting bov should hiss?

2. can you feel the fuel cut-off on an 88 turbo? my after market boost gauge says im over 5.5 psi by at least 3 psi. intake/exhaust done.


thanks chev

 

mine "hiss's" on a normal basis sometimes reading below atmospheric pressure, but its not loud or anything

 

1. like -10 psi, just because even if the guage shows negative, it will still build pressure after you snap the throttle plates closed, then the bov will sound

2. yes, you can feel it. and it's not a good feeling.

 

you will definately feel it hit cut off. its a feeling that you will know. Probably scare you shitless into thinking you broke something too.

 

wierd, before i felt it, it was like a bad engine hiccup. but now it doesnt, and im well over stock values.. havent done anything differ either. other than fix my bov. lol, these cars are a hoot!

 

yeah i hit fuel cut once, i crapped my pantaloons, got all paranoid. 8.8psi is when fuel cut comes on, avoid it like the plague.

 

I hit fuel cut beffore as well... about 10 times at least. On mine it felt like ignition misfire or something.. not like a wall where the car does not pull at all, just a misfire. Dont ask why i hit it so many times, i had an FCD.
