Hey guys, on the mech pump for 2.8 can you control how much boost with the compensator adjusted and tap screwed in if the turbo is free spooling/waste gate not connected?
Currently only reaches 18 psi with wastegate not connected the fuel screw has been screwed in quite abit that my idle screw is no longer in use and idles at 800. My understanding of the boost compensator is limited and I've never touched it but I bought this car with factory turbo that boosted to 18. I've fitted a vf10 with vf10 exhaust housing and 2.5 inch downpipe since then. increase in power has been insane, the whole front lifts up and bottom sits down at 90kph flooring it, no smoke. I have a boost tap I can only get 10 psi with the boost tap with 12 turns out when its connected. I'm just trying to understand why its only 18 psi when boost tap not connected and not greater, whats controlling it?
