Hello all.
I installed an upgraded intercooler a few weeks ago and so far its working out pretty well I think. Makes a cool swirling noise between 5 inHG and 10 psi. Higher RPMs feel better. But it is a little hard to tell because it has been pretty cold outside since I installed it.
However, since the install sometimes when I start driving aggressively i will hear a ppprttt (squeak) noise for a fraction of a second. It almost sounds like an after market blow off valve (except I am still using the stock one) or almost like a tire chirp. So I am wondering 1. if I didn't clamp the hoses tight enough (because they were very difficult to tighten down based on their location and it occasionally leaks. 2. the intercooler is moving under load and rubbing up against something (because the mounting brackets had a little play in them) or finally 3. is just the noise of highly pressurized air hitting the bars and plate design.
When I hear this noise I don't see the boost gauge dip on the screen. And I don't feel loss of power. Would the boost gauge be able to show a brief loss in pressure like that? At peak, I seem to be making about 23psi under certain conditions with my FPTune.
What are the symptoms of a boost leak? How consistent do they tend to be?
What does a boost leak sound like, and would I still be making boost even with one?
Where is boost pressure measured? (and how accurate is it)
