From my understanding you can only do it with a custom tune
Anybody have a diagram for the 3.4L whipple? Its a little different and would like to see a picture. Trying to finish up my buddies car.
Anybody? I know there are plenty 3.4 cars out there!!
+1 i,am fixing to do mine i just want to make sure i do it right.
Uhhh... That link has been proven to be the wrong way to do the boost bypass (generates more heat) and you are saying this EGR delete thread basically incorporates the wrong way to the boost bypass as well?
Threads been up almost 2 years, my car made 670/600 with no heating, tuning or drivablity problems. Tell us all what's wrong and make a constructive recommendation before you just come into a proven "How To" thread with useless information and no contructive feedback. :shrug:
The bypass still works in this confoiguration. It opens under vacuum and closes under boost. Stock does the same truing but the solenoid could pull boost out of the system even under wot.
This mod makes the bypass work just like every other bypass valve or wastegate.
Sorry. Let me clarify
The items in question is on the second paragraph on the first post of the thread below.
If this EGR delete thread incorporates the RPM outlet way of doing the boost bypass, then we should research how to incorporate the revised boost bypass into the EGR delete and update this thread.
If you or anyone else figures out a better way, let me know and I will update the thread. I don't have a Cobra to work with any longer.
This egr delete does incorporate that method, that method rearranges the vaccum lines so that the bypass valve gets a signal directly from the intake instead of from the solenoid. The way this ehr delete is written up its done the same way, but since the lines are all being redone u don't just simply swap the lines around.
quick question, can the original 3 way grommet be used for us eaton guys instead of the brass fitting? one to frps, one to boost bypass and the last to the boost gauge?
See page 4 post #93. Rich Gill did it on his car and it came out really nice. :beer:
Great write up man im still using it today haha
Awesome will be doing this tomorrow
Just did this today and was wondering where you guys got your t-fittings from? I couldnt find anything that would work in brass. I only found a plastic T from Autozone that might work.
I think Autozone has the brass T fittings in the misc parts section, the section that sells stuff like push clips, replace door handles, nuts bolts etc... If not, you can reuse the 3 way fitting from the OEM set up or try another store like Pepboys or hardware store.
How did you modify the stock plastic vacuum lines?
What is the thread of the cap that goes on the manifold?
so if you do not connect the line to the back up to the air intake. do you just plug it?
I capped mine off
