ebpv and butterfly valve delete...

So I got bored and decided it was time to change the turbo o rings because of the slow leak... While I was at it I did the ebpv mod, and took out the butterfly valve. when I took the turbo out I noticed a bad up pipe leak...

long story short, snapped 3 of the 4 bolts off on the adapter manifold, had to order a new one 118 bucks. turned into a 3 day job. wow lining up that adapter flange is a BIAAATCH!!! WOW. anyway, then tightening up the bolts on the up pipe flanges with the turbo in is a bear...

But- after it was all buttoned up it boosts up way quicker, egts are down significantly, and it runs much better. the only thing that gets me is how much different it sounds. It sounds WAY different without that valve taking up all that space in the exhaust port of the turbo. I would recommend this mod to anyone.

Yep I agree, a noticeable difference and sound in both my early '99 and '02 Excursion. EGTs are down a bit. Hooking up the adapter flange in my early '99 is quite easy since the turbo is smaller and more room to work with. What I found out when putting the turbo back on in the later trucks is to mount turbo and torque first, then hook up the adapter flange WHILE the uppipes are dangling and free from the exhaust manifold, then finally hooking up the exhaust manifold bolts to uppipes.

Ya it made a very big difference on mine, My actuator was messing up and semi-engaging my ebpv... The up pipes are a pain, I loosened the passenger side up pipe down by the exhaust manifold and was able to remove the adapter flange and put the new one on, when I was lining it up with the turbo I tightened the rear bold on the passenger side flange because its basically impossible to get to, and left the other bolt loose and it allowed me to move the adapter flange into place. I was able to tighten the other bolts with a long extension and a wobbly. Im getting about 3-4 more pounds of boost now due to fixing the up pipe leak it had, but its taking me a while to get used to how much different the turbo sounds. sounds so much more open.

How did it affect the sound? Louder? deeper? More whistle?

Sound? Since my truck is has the 6 speed, between shifts it sounds like a crowd cheering at a football game whereas before I'd hear the usual blowoff.

Ya the blow off is pretty wild. Much louder "log truck" turbo sound out the pipe.
