[QUOTE="robvas, post: 17033222, member: 199382"] Chasing down a little issue where I am only seeing about 6lbs of boost on the initial hit. It seems to go up a little but it's hard to keep an eye on the gauge, the tach, and the road at redline to see where the boost is at... 3.73, 3rd gear is 98mph at 7500rpm Put a new belt on, didn't make a difference, so I started looking at vacuum lines. Car feels fast but I haven't done a 60-130 or raced something where I can get an idea of how fast the car is. I would think with a 3.250" pulley and longtubes, I should be seeing about 9lbs? 10psi is what the pulley is rated at. 3.625" pulley is the 7lb pulley. This compression fitting to a rubber vacuum line might be it. This line goes to the boost gauge (also a hard copper line to the blower? Never seen that before) I replaced the worm clamp on the elbow, that was barely holding on to the boost actuator, and that didn't seem to change anything either. [/QUOTE]
