Help! I have a turkey in my turbo!
I just did my intercooler install and now have major issues with I believe it's compressor surge when I lift off the throttle.
I have a smaller intercooler 18"x 12" x3" with 2.5" inlet and outlet
I did an over the rad from turbo to intercooler using 2" piping and to 2.5"
I routed around the a/c and rad using 2.5" piping to throttle body.
I have IAC hooked up and my BOV is 3" from throttle body.
I have the signal line for the BOV from the nipple right after the throttle body
After hooking everything up, It idled great, no leaks from spraying the couplers, and idle AFR's were good.
I took it for a drive in the parking lot and every time I would be in boost and then let off I hear this awful sound coming from the turbo side. Kinda like the turkey gobble.
From what I've read I thought I hooked everything up correctly. Does anyone have any suggestions of what to check.
BOV worked correctly before when I was running non-intercooled but now I not so sure. Oh BOV is a knock off RS I also have a friends knock off type S but it has two vac nipples and I'm not sure how to hook that up.
thanks for the help
