Greddy Turbo owners thread

/\ Shelldudes was still in the babying phase and Frosty's didn't sound like it did many miles either .
If guys are not getting many miles from thier turbos with the correct restrictor in place and not even pushing the turbo hard either then there has to be another issue as well .

Some possibilities off the top of my head
*Restrictor too big or too small
*Drain too small or too long or not direct enough (ie sharp bends)
*Poor BOV setup . IE compressor able to surge due to spring set too tight
*Poor BOV/Boost control setup . IE turbo able to spool up to high pressure at low flow at part throttle.
*poor oil quality (ie no filter on supply line combined with poor oil change habits)
*oil under or overheating
*Wrong oil used

Pretty sure it's a bearing... Got it delivered to KDR today via flatbed. Had the restrictor discussion with Dave.... need to talk more about the oil inlet/return. BOV is to atmosphere... Synapse... now that Dave's got it I'll likely have him recirculate it since it'll be away from home for some yet disclosed amount of time. Also considering dropping the Synapse all together. Boost has been nice and smooth from the get go... haven't had any spikes or anything like that. Oil has been 10w-40 since day one with the snail (did notice a significant increase in pressure when I cutover)... Have changed it twice in the 4000 or so miles (once at 500 and a second time a couple weeks back)... have been running RP. I keep out of boost until oil is no lower than 140.... it normally hovers between 165-180.

I stay in auto.... it definitely gets explosive in manumatic mode, but fullly auto i've had zero issues... I am looking forward to the recirc change now that I'm over the whole "hiss" thing. I may even go with one of the alternate "leaky" settings since the blow off will be reclaimed... a known "feature" of the synapse... silly synapse says it's a benefit... go figure... hks or greddy are also definite options.
