i recently had been searching for answers to some of my questions regarding
the oiling specs for the tdohr 16g6 10.5 after calling dealerships everywhere and
getting stupid replies and unsatisfactory answers i stumbled onto this site.
i was happy to find at least something satisfactory so thanks to those who
posted this info http://store.forcedperformance.net/merchant2/graphics/subaru_oil/MHI_Oil_Specs.pdf
http://www.dsmtuners.com/forums/turbo-system-tech/283578-lets-talk-4g63-turbo-oil-feed-supply-locations-all-turbo-brands-2.html
BUT it seemed there was a lot of speculation as to what the contents
meant...and i would have said something but for one it was a dead thread. and
two this is my first and probably last post as even though i am modifying my car
with an evo 8 mr turbo i am not a dsm owner...and apparently a "newb" to these
forums
definately not to say i dont appreciate the dsm community and its vehicles..i like
evo's way more than i like subies...
dont get me started...
so if i can shed some light onto this threads content and confusion...one member
stated that at (wot) the maximum psi was quote
"the recommended full load pressure is 3.5kg/cm2(49.7 psi) which almost
excatly what i get at wot. i checked with my mechanical pressure gauge."
problem is the pdf in which he sites this information lists multiple variables for
three sets of criteria
· The required oil pressure (continuous) at Full Load Rated Speed: 2 ~ 5
kg/cm2.
· The recommended oil pressure at F.L.R.S. 3 ~ 3.5 kg/cm2.
· Min oil pressure requirement at low idle at warm condition is 0.8 kg/cm2.
the tilde (~) denotes a range or a variable
in laymans terms
1 =minimum of 28psi to 71psi at continuous full load, so romping on it. (past 71 would be oil seal blowing)
2=the recomended oil pressure for just F.L.R.S. (full load rated speed) 42psi to 49psi.
3=minimum oil pressure at idle (hot) 11psi......
so heres the issue...if a "typical MHI turbo" is pretty much the same acrossed
the board...the blowout psi would sit at an average of 69-72psi....because 71 psi
is the maximum at full continuous load at full load
rated speed...not just full load rated speed or (wot) wide open throttle...which
would be 42psi to 49psi which would not blow out the seals
so your standard mitsubishi turbo only really sits 4 psi lower on its seals than the
average industry aftermarket turbo..i woul look to other reasons for failure
such as tapping into the filters oil with a sandwhich plate (oil contamination)
i personally have an oil filter relocation kit and oil cooler and tapped into the
clean line from the filter going to my cooler to my block...but for me thats a
good psi rated point for my car...not over these specs and not under.
so remember 71 psi is the average max psi on our turbo's.
i just felt it imortant for people like me who are building twin scroll kits to be
able to source the correct information for our setups...thanks again and keep
kicking ass with the dsm's
anyways thanks for your time and patients...hope this helped
