Wasp,
nothing has changed. Remember straight from the factory I had BOV leaks due to bad harness ( took em 3 months to figure that one). It wasnt even audible, but u could see the guage flutter.
Fact remains on another car, with aftermarket setup ( BOV+BOP), it did pick up 2+PSI after ditching the Stock Surge Valve. Maybe he had a slight leak too.....but we'll never know cuz he ditched that setup.

Originally posted by bubba nice. but i have a few questions:
1. is stg1 like stock where the boost solenoid needs to see boost? (or did bypassing them like you did remedy that)
The solenoids do not need to see boost except the TIP solenoid which controls the what the TIP sensor sees.
2. where does the line with the check valve go to the turbo? and which way does that particular check valve go? (obviously the brake booster needs the vacuum so it is self explanitory)
The line goes to the vacuume nipple on the neck of the compressor housing of the turbo. The chack valves go just as they are shown in the pic.
3. are you noticing timing being pulled?
Definately no timing being pulled as long as you are not running outragous boost on pump gas.
4. do you need a guinnea pig for your piggyback in california?
Originally posted by cali You know what, you're right. You have a drag car, and the effects of the slow leak are nominal especially when youre WOT most of the time.
For a daily driver, it is better using the stock lines.
Actually we drive this car everyday. For the class we are running this car in, it must b street legal and registered. We have no blow off issues.
Edit: And several of us (Maybe 5?) dynoed 2 weeks ago with stock routing over 19PSI without any leaking.
I am in no way saying that everyone MUST do this. I am just sharing what works best for us. If you dan't want me to share info then I will keep it to myself. Should we take a vote?

To me thats bullshit. I personally appreciate everybody who offers info like PSI is offering here but to hold it back because some people don't agree with it? Or imply that you might not next time? You can keep it.

Calm down there tough guy. I am not holding any good info nor will I ever. I was just joking around. Sharing info is what makes our car develope into a real threat. We have allot of work to do inorder to make the Diamond star camp shake in their tennis shoes.

Hey man I aint trying to with you guys. You have proven your shit over and over again. I'm just doing the same.....making a suggestion.
Wouldnt you agree with me that for a daily driver , the way I described is better?

Not trying to be a tough guy at all. I agree 100% with the idea of sharing. All is good
Sure the factory setup works, but when we tried to run more boost, the BOV would crack open. Think about it for a min. Why is there a solenoid to control a BOV/BPV? Typically you need 2 vacuume sources:1 before the throttle body and one after. When you are WOT the pressure is the same on both sides of the BPV diaphram therefor the spring pressure keeps it shut. When you close throttle on boost, there is a huge difference between the vacuume on one side and boost on the other. The force of the spring is overcome and the valve pops open. This method works great and is pretty much fool proof. What reason would the factory have to put a solenoid in the mix? 1 big reason, to spoil the fun and to keep the bozos out there from blowing up their motors. When the ECU realizes that it can not control boost via the wastegate it will resort to cracking open the BPV. We have tested this over and over again and everytime the BPV would open above 17psi when set with the MBC. This isn't holy grail of info. This is just what we found with our research.
I don't understand what your point is. I am not saying that you are wrong by any means. What I am saying is that the BPV solenoid is not necessary, and FOR US it impeaded the boost levels that we were aiming for.
1. The Blue line is a higher pressure at ALL TIMES.
2. The Black line ( to surge solenoid) is from the Manifold.
3. Throttle open, solenoid changes source to blue line.
4. Throttle closed, solenoid changes source to manifold.
Check valves are like a oneway road for vacuume/boost. Air can travel through them in 1 direction. I have the check valves shown in the pic that I drew up. There are 2 green check valves on a "T". Take a look at the diagram and you can see how I have them setup.
I'll jump in with a stupid question. I think I understand what Cali's saying. The way you have it set up, with the Mopar BOV will it blow off constantly unless at WOT? I know we had that problem with Tim's car before.

What do you mean constantly blow-off.
No matter what a Blow-Off
Or when you let off the gas, decelerate, clutch...Anything that makes pressure difference between the BOV and the attadching line.
