Of course the IC upgrade is worth it, but I would not attempt the install without the Orings i mentioned above. Since you have all this information before doing the install, i suspect you can get it right the first time and avoid going through multiple installs and trial and error. Just get the Orings and test the CP-IC connection with the IC on the ground. Once you are confident one of the Orings will seal, the install itself isnt bad at all. |

That's what I figured after looking over the log and also noticed that the wgdc was slightly higher than before. Reset the adaption but haven't gotten a chance to do another log. |

Hi all, been reading this thread and I'm about to get my CP installed and I just want to make sure I put the O rings in correctly.
As mentioned the O rings from the CP to the IC is directional. which way should it be if say the top was the CP and bottom was IC. I've been playing around with both ways and both seems to fit in nicely, although one way was a lot easier to go in than the other. It seems like the O ring on the left of the CP in the picture is the right way if I was to put it in, but I could be wrong. See pictures below. Last edited by G80S58; 11-08-2019 at 10:39 AM.. |

in your pic, the o-ring on the right is the correct orientation

When you install, you can lightly oil with motor oil. Just make sure the Oring does not wrinkle. If there is any side to side play once the CP is clipped on, i would be suspicious of a potential boost leak. |

I would recommend the oil, but it may not be "required". Just dab your finger in motor oil and wipe it around the circumference on the Oring. You can even use oil that may already be in your CP. You just dont want the Oring to catch and wrinkle or not sit correctly if its a tight fit when you slide on. Some people use silicone lubricant or something else, but oil is usually already there.

Ordered all of them, though I only have oil/grease leaking from the intercooler to charge pipe connection so that is where I will start.

I flashed BM3 and sent them some logs for stage 1, I have a delta between boost and target, but it's well within spec and deemed normal so I think these o rings are absolutely the way to go!

To test and confirm fitment, I swapped my cold side o-ring to the the 4.5mm x 60mm o-ring after lightly sanding it to reduce it's outside diameter. I slipped it over a 2-1/4" hole saw in my power drill and sanded the outside edge with some 200 grit sandpaper. I checked it with a micrometer and ended up at 4.42 to 4.43 mm. Still a VERY tight fit. Still no leaks at 30 psi. Thanks to the thejeremyman9 for the addition. I've added it to the first post.

Just for leak testing. I've run 28 psi tapering to 24 psi, briefly, on my PS2 in the past. That could be why they break on me. I'd like to be able to run 20 psi flat all the time, but when I've tried that on PS2s at this altitude, they don't last long.

Having mine installed by my shop today. They tried to talk me out of it but I told them hardparker knows what the hell he's doing
Will report back with any differences.
