Boost loss.

The kit was premade so, I have no idea. The tubes are not run the 'long way'. They're run like every other IC kit for a Civic. There's aprx. 7ft. total of pipe from the turbo to the intercooler, to the intake manifold.
I'll check for leaks and such thursday when I switch out the CX tranny for the EX I bought this weekend.

btw, larger volume in the IC and longer IC pipes wont cause a loss in boost, only in spool up time.

mismatched volumes within the intake tract will cause pressure drop due to a turbo's fixed amount of flow.
volume doesnt change, but due to changing restrictions in an improperly set up turbo system will change pressure readings.
compare it with a 4" hose and a 1" garden hose both flowing the same amount of water... the 1" will have more pressure due to more restriction, but in the end still will flow the same fixed amount of water for both hoses.

i see what you're saying. But the turbo is set to build boost to 7 psi then no more. So it would still fill up the larger "garden hose" a little bit slower, but still should built to 7 then stop. The garden hose is a good analogy, but not perfect since the intake tract isnt an open system. Its like having the hose plugged at the end except for a little hole, with the water pressure only being 7psi. I still think he had a bottle neck at the intercooler since he's most likely using one with a few long tubes. The boost gauge is probably at the manifold, so he sees the pressure after the cork.
I went from factory IC pipes and a semi-restrictive factory IC to a VERY high flowing, almost zero pressure drop Spearco IC with very smooth mandrel bent 2.5" IC pipes. I picked UP a few PSI with just that change, and the engine revved MUCH quicker.

Didn't work, still only have 5psi I moved the line from the compressor to the BOV. I'll try the intake manifold.
dont attach it to the BOV... you can tee off the FPR to the wastegate.. that way the wastegate actually sees true manifold pressure. i would just check to make sure that all your fittings are good and tight.. even of they dont blow off, they can still seep out boost
