I'm new to the whole hyped up 4 clylinder deal and i was wondering what a blow off valve is and what it does. Please help me.

 

If you have a SRT-4, you technically already have a BOV which vents the excess boost to the atmosphere, but it does it very, very quietly. The Mopar BOV which most of the postings talk about here, makes the sound a lot louder, for a price of around $65.

Think of the air brakes on an 18 Wheeler......PSSSSHHHHHHH!!!!

Everytime you shift the gears, gotta love it or gotta hate it......it's up to you.

 

Man i love that sound. I thought that was the wastegate acuator at first when i joined but someone redireted me. Welcome to Dodge forum Wayne.

 

Thanks for the replys. I have a black 04 SRT-4 i got it @ 3 weeks ago and I'm lovin it. But faster is always better so i need lots of help in the area of 4cylinders. Thanks again

 

The BOV won't make it go any faster, but it WILL sound bad A**!!!!

 

To be technically correct, the stock "BOV" is actually a diverter valve (common name) or surge valve (PVO/SRT) name.
It's not a BOV since it send that excess boost back into the intake, hence the low volume. the Mopar plate "diverts" that pressurized air back into the atmosphere, hence the louder sound.

Finally put a Mopar plate on a local owners car, WHAT A PITA!!!!! Forge MUCH easier!!!!!!!!!! No gasket, one piece, no sealant.
I can finally compare them instalation-wise.

 

I was wondering how well the Forge seals during high boost situations, because I have read that the stock valve tends to leak boost over 18 psi.
