In response to In response to 40


          

yeah, 10 psi and 30 degrees of timing is bad . but, on the positive side, at partial throttle, you aren't putting the engine under as much load as maximum, even though boost pressure is being made in the manifold. usu. when you hit max pressure on the map sensor, the timing should fall back down to around 20 degrees. hmm.....if the ignition timing isn't falling to safe levels at partial throttle boost, then there is a problem .......I have only checked my timing under these conditions a few times, and I am not 100% positive that ignition timing falls during this condition. if it does, no worries. if it doesn't.........ewuuu. realistically, timing should drop as soon as you hit boost. on my car, at partial throttle boost, my car never really "rattled" like it woudl if it had that much timing. I woudl look "really close" at the dattalogger (this goes to anybody that has a logger and a turbo, as my car is kinda disqualified from this for the next couple of weeks ). and see what the timing is. with such a big turbine housing as the super series turbos have, the timing should drop from boost pressure and throttle position under partial throttle boost. if it doesn't........I honestly don't know hwo to get around it unless you run some kind of timing retard device that would de-activate at 100% throttle and activate at 0 psi. I think that you will be ok 'though. best thing to do it check and tell us the results of partial throttle boost via spark advance on the datalogger, egt and guestamite air/fuel ratio if possible.
