Orwell gets boosted (another 1.8t 20v swap) by mk1vDUBtec

4 minute(s) of a 91 minute read

so yesterday I drove the gti for the first time in 2 weeks... I was holding 12psi and peaking at 15...
Then last night it was about 10 psi. It's 10 psi again today. I know it's really hot out, but can the heat change the air density that much that it'll increase my boost up 5psi??
I'm confused. something's weird.

hahaha
I did a boost leak test a few weeks ago. Put the plug where the air filter goes on and filled it up to 20psi. It leaked down fairly quickly. I could feel a little coming out of the N75 at the port that I have vented to atmosphere... Is that normal?
That's also how I found that my injectors were leaking. I replaced all the o-rings for those though and no improvement. (well maybe 1psi?). I tightened all my connections and checked all my ports. I can't find a leak. I'm not saying that there's not one there, just that I'm having a really tough time finding it, especially when it all leaks down in under 10 seconds.
I'm thinking it must be a boost leak... cuz I'm now peaking at 10 and holding 8ish.
I borrowed a spare N75 valve from a friend. I'm gonna swap them out and see if it does anything.
then I'm gonna unplug the wastegate and do a smooth rev. It should hold unlimited boost right? If not, then it's probably a problem with my wastegate I'm thinking (but i'm leaning away from that).

borrowed a smoke tester from work. only goes up to 30in h20 though (which is like 1 psi lol) so I filled the system with smoke from tapping into the fpr line and then hooked the compressor up. smoke was coming out of my n75 (the port i vent to atmosphere).
so then I plugged my buddy's n75 in and started it up. No improvement.
Messed with some lines, boost gauge, etc. Then I just ran it while I sprayed every connection I could find with brake cleaner. Nothing no rough idle at any connection. Happened to look back at my gauge. reads -20 now. wtf? how does spraying brake cleaner make it beter? weird.
Needed to go to work so we called it a day. on the way to work still only peakin at 10 psi, holding 9ish, with my buddy's n75 still plugged in.

went out for lunch to BK. I owed my friend a ride so I got on it. Seemed like she was pulling harder than usual so I looked down and was holding 15psi. wtf is going on? Ran absolutely great and pulled very hard. Parked the car. had lunch. filled her up at wawa for gas. got on it on the way back to work, back down to 10 psi.

I'm being tormented.

now holding 20 psi. I think it was the N75. and the pedal gets stiff after 10/15. Didn't realize I could press harder and hit 20.   I feel retarded.

This thing pulls hard as a motherf*cker.
I'm scared to take it to 20psi though. The boost gauge I'm running right now peaks at 20. I'm scared I might run higher and not know it...

And thanks Trevor! I've got a friend with a tacoma that lives in york. He sent me a pic of a rabbit by him. It's got a checkerboard hood and roof. Is that you?
