boost leak tester from z1 with gauge. started at 7psi on the compressor regulator and my friend went all the way up to 40psi just to try and get something or hear it better. never could get any built and could only hear the air rushing through the pipes. Sprayed down a few spots we thought might be leaking around the intercoolers with soapy water and nothing. He knew the risk of blowing out the cam seals but the leak is bad enough that it wouldnt build any pressure at all even at 40psi!
