the mopar bov and stock surge valve can hold higher huh? i didnt know that acording to everyone else it leaks past 18psi. even modernperformace says it leaks past 18psi.

 

had 3 sets of eyes on it during the mesurement and install it was spot on.

 

Sure can, I have tested mine to hold 20 with no problem at all even built a test rig for it. "Everyone else" either does not understand how it works, or are taking the word of someone else. And as much as I like Modern, they are wrong. Keep in mind, they sell BOVs

See, boost gets applied to both side. So no matter how much pressure is on the turbo side, there is that much PLUS the spring pressure.

10psi + 1lb spring will always hold against 10 psi

20psi + 1lb spring will always hold against 20psi

And don't worry about the spring wearing out. I tested my stocker at 45K and it matched the one with only 5K that I had tested previously.

And I have to disagree about spike, guys. Back when I was S2, I hit and held my boost level til the redline droppoff. Summer, 16.5-17, winter 15-16. Just went and held. Stage 3 acts the same. Hit 20 and stick.

 

My stage 2 spikes past 20, and falls to 16 by redline. But I have some theories as to why...


Either way, as far as Mopar BOV, listen to people who aren't trying to sell you anything, or people who haven't spent $400 on hard pipes and an aftermarket BOV. No need to repeat anything glhs637 said, but that information came from SRT. One of the guys posted it on srtforums.com. I copied and pasted it, so I have it. Basically, moving to another BOV is a downgrade.

 

i was thinking that cosidering dodge sticks with stock bov above 20 psi for stage 3 kit.

 

i have the mopar bov and i personaly dont have any problems with it. thats just what everyone says i havent tested it myself but if you have and say it can hold 20psi then ill go with your word.

 

ran my car today and it was holding 17 psi so i guess weather has alot to do with peek boost.
