No boost, whiny sound after pull with xHP. Pulls good vacuum
Hello, new to posting on forums, normally I just ghost read to fix my issues. Recently installed xHP and was doing a small pull, only going to about 5500 rpm before shifting and 19psi (MHD stage 2+). Felt fine but was just pulling into work so didn’t notice anything weird after. Then I get in after changing settings on xHP and my boost gauge (T-d into a line between BOV and intake manifold) won’t read more than 3 or 4 hp and I’m making no boost. Slight whine and sounds kinda like a boost leak but nowhere near what it would be if it was just a charge pipe leak or something where you can hear 20 psi escaping. It seems to just not be producing boost but I can’t narrow down what’s causing it. It pulls great vacuum tho. Attached is a log with two small pulls. Stock turbos. No codes (yet). Seems like all the connections are fine…
https://datazap.me/u/combl3/no-*****?log=0&data=3-12 I don’t want to throw more money and parts at it as I just replaced Vanos solenoids, crankshaft position sensor, installed a catch can (it seems one of the clips on the breather hose is broke, could this cause this?) and a whole bunch of other parts that normally fail. wondering if someone smarter than I could narrow down if it’s a boost leak or a blown turbo with logs. I don’t like driving an n52 so any help is appreciated. Last edited by C0mbl3; 04-17-2024 at 06:43 PM.. |

Well this weekend I did some digging and my intercooler piping decided it didn’t want to be connected to the cooler anymore. Kinda a PITA to fix as the piping wanted to slip off the pipe going to the charge pipe no matter what I did…. Seems like if you get the hose clamp too tight it’ll push the rubber pipe off so it took a little sketchy finagling to stay on securely
