Your right, he is. He was the go-to vendor back in the day....but, he screwed that up for himself.

I never would have recommended him if I wrote this recently.

Holy cow! I had no idea he was a trouble maker.

I will put up a ton more pictures tomorrow. But man. Car runs SOOOOO much better now. No more fluttering at all. A very nice long HISSSSSSS.

The only problem I ran into was that I had to run another vacuum T since I have a S3 fuel rail. The assorted box I got of vacuum T's has different sizes of course but on all three ends of the "T" they are the same size. It would be nice for them to have a smaller size on one side and not just the T section.

Uh what? Get a video of this so called squealing. And what is your vac idle at?

Just adding to this thread:
I got the P2R vacuum block. It did not come with any fittings but I expected that for the $35 shipped price tag.
I spent around $14.50 for brass fittings at the hardware store.
2- 3/8'' Hex Plug
1- 1/8'' Hex Plug
2- 1/8''HB X 1/8"MPT Barb fitting
2- 1/4"HB X 1/8"MPT Barb fitting
Put a nice line of liquid teflon around the 3rd from top thread on each one and tightened it down tight.

Here are various picts:

^Mock up of the fittings and where I want them before teflon


Mounted on battery tray. ^



All vac lines hooked up.


Intake on, still need to put in a couple connections and straighten out catch can.

Hmmm did this vacuum mode to a locals SRT-4, causes his Mopar BOV to go off during WOT.... Like its leaking...

check the lines going to the BOV sounds like he has a leak.

Boost leak tested, no leaks at all. He just said when he starts to go WOT he hears it going off. I think its because we hooked the surgevalve up to the TB. Way more pressue causing it to open up prematurely?

Did you notice the part about the required spring mod?? Either that or the surge valve may be bad.

The pressure difference between the outlet of the turbo and at the TB is about 2PSI (with stock IC and piping) and stock the surge has a 4 psi spring. You should be fine. Think about it at WOT you should have boost level X at the outlet of the turbo and behind the valve you will have Boost level X-2 but you have a 4lb spring so roughly X-2+4 or X+2. Does he have an intake? Could it be the sound of the turbo sucking in air? or like master said could be a bad valve. Not ripping on either of you just want to make sure we are dealing with a horse not a zebra.

Also this was done by PTP who for lack of a better word is an idiot. I had a set of hard pipes and an HKS BOV. Still had a little and it was from the very small pressure wave still left in the line. It is inherent to such a small turbo with a relatively larger motor. You gain absolutely nothing by doing this mod if anything you risk wearing your turbo out faster since surge valve response time is slowed so the pressure wave has plenty of time to smash back into the turbine.
