xr6tee9 Member 82 Member For: 11y 3m 21d Gender: Male Location: adelaide Posted 12/02/14 07:38 AM Share Posted 12/02/14 07:38 AM gday all, just removed my turbo and had comp wheel replaced and vsr due to an unfortunate incident.. I forgot to mark the compressor and turbine sides with the core so had to dummy fit to make sure dump and pipes were all lined up and werent fouling.. was wondering what the term 1/2 hole preload meant..?? I didnt undo the adjuster on actuator, but set it up so the rod was coming directly paralell from it.. everything lines up beautiful and after driving it (it might be just me?) but it seems to flutter more coming off the power.. could I have the comp cover turned a little in one direction from b4 repair, would this affect preload that much?? im guessing its a c*nt of a job to adjust on the car?? with 4in dump etc..

(normally done for high boost applications)I guess with the higher spring load the actuator won't necessarily open as commanded, but I could be wrong about that, I don't know how good the boost control in the falcon is for making up for differences like that.
