horsepower curves and torque curves are all familiar stuff, but what about boost curves? With stock turbos, are you supposed to hit a boost limit at a certain rpm (say, 4000) and then the boost stays locked in at that level until redline? My turbos seem to be kicking in ever so slightly late, and continue to build boost linearly to .85 bar at 8000rpm.
Pretty sure that my new Apexi Boost solenoid must have been plumbed wrong. With stock turbos(stock intakes, cams, big exhaust), at what rpm can 1 bar of boost be attained? I tried, on a lark, just switching the two tubes. No difference, although the question is always, will I break something??
The Apexi unit is supposed to be plumbed simply - one end to a vacuum source from the intake, the other end directly to the wastegate actuators. So far as I can see, mine was just plumbed into the stock maze of plumbing. Instead of rerouting everything, would it be possible to just seal off a portion? I really would like to have precise and direct control of my turbos, and have 1 bar full boost come in nice and early
