i was up at my local drag strip( eighth mile) and i made a run and the time was a 10.1?? now im a pretty good driver and i dont think it was opperator error, but when i got into the upper rpms the car felt like it didnt have any left. so i pull over to my pit area and pop the hood. my friend who has a turbo ll and he suggested put my BOVs back in. so i did and ran a 9.7. still **** but getting better. could the stock bov be shot and leaking or do i have a bigger problem? thanks guys.
o cars all stock except DP

 

do you have a boost gauge?

 

yeah but it wasnt hooked up that night.

 

any ideas please

 

You need to get a boost gauge and check your boost pattern before anyone can suggest anything.

 

k just got back from checking the boost. 10 psi until 4500 then drops to 5 or 6psi and stays.

 

How's your oil?

 

oil is fine

 

so you had an aftermarket BOV installed and now have the stock ones in place again?

sounds to me like you have a boost leak somewhere, the Y-pipe connector likes to split in half so i would check that first then check over to see if you can notice any vacuum lines cracked or broken/disconnected anywhere.

 

could it be where the bovs come out of the y pipe. mabey the hoses arent on tight?

 

doubtful, usually they would have to be cracked/split to create a boost leak.

 

hummm. any more ideas besides checking the vacuum hoses

 

Catch, you just need to look at all parts of the system that deal with secondary boost and then start checking them:

There is no smoking gun on these problems, you just have to get dirty.
