More Boost. Quieter Bov ?

[ztuned]

hey guys,

no i didnt make this thread because i want a louder BOV or something

I recently blew my stock r33 gtst turbo. and i now have a GT-RS in there, but the tuner is having some issues getting over 300rwhp

the engine keeps knocking if he tries to push it any further...zzz

comp test and leak down test have been done, and everything seems fine. still cant find the prob

i have the usual mods

exhaust

fmic

pfc

avc-r

z32 afm

740cc injectors

pod

fuel pump

the question is though, the ebc is set to 17psi

but why is the bov releasing shit all air, being very quiet. i have tried putting the stock bov back one, and that one is also very quiet?

shouldnt it being louder as the car is now running more boost?

it is a LOT quieter, sometimes cant even hear anything compared to when the stock turbo was in, and the stock turbo was running 11psi only

and i also notice the suction noise from the pod is also quieter

so is less air getting into the engine? is something restricting it?

all i can think of is that some bits of the compressor wheel from my blown turbo is stuck on the turbo side of the fmic core?

or am i being a noob and is this normal? lol

i dont really care that the bov is quiet now, i just wanna know if there is a problem

cheers

Did you have it checked after you blew your stock turbo to see if there was any internal damage?

timing perhaps cam gears time

There is definately no boost leak?

How do you know it's running 17psi? Is that the reading from the EBC or dyno software?

[ztuned]

comp and leak down test has been done b4 tuning so i know the engine is fine

i know it's running 17psi because it is set to 17psi on the ebc and also it shows that on the boost gauge

so all this doesnt sounds normal? more boost should make it louder right?

[H@ME]

yeah it should theoretically..also depending on the BOV used but generally yeah more boost it should be louder?! hope the turbo is ok..

[ztuned]

lol ur not serious? the turbo is brand new

[H@ME]

well thinking it over again, if the EBC and boost gauge is reading 17psi means the turbo is boosting, so boost is there so no it shouldn't be the turbo..it an interesting problem you hav there.
