Are yall saying I cant see? LoL --probably right--some advantages--this way i cant tell what i look like in the mornings
Ok --all kidding aside it still looks like it is a dead end branch that is feed by the line that continues onward to the omp and there it dead ends?. Am I hallucinating? Again?
Since the omp is the only outlet for this oil line --that is not good? We know that the omp flows slow---very slow; and flow is important to a main bearing like this? I bet the oil is a little hotter also? Now am i missing something here? Does the front bearing have a wheep hole to help? Getting oil to the bearing is one thing--getting flow of continious fresh oil is another.
Paul --cant wait until I get my tinkering little hands on that!. Just in time for me to send my first oil analysis. Perfect.
I will be supplying data from my old setup --starting today and then of course the new. Anyone need install pics?

Yes it goes into the OMP but then is distributed through the clear plastic tubes to the oil injectors to be injected into the combustion chamber. But I guess it does dead end in a way and I was thinking the same thing about the oil temp at that point.

that is want i am wondering---of course it has to drain-- and gets squeezed out --but how much flow is present there? obviously the film strength is not protecting the bearing there--but is it because it is getting to hot, not enough flow and/or of course too low viscosity?
It seems to me that would be a very stagnant flow area? Flow of oil is also used to cool the area being lubricated?
That could be better?

Well, if it dead-ended right there, that would actually be ideal, as that way the pressure in the lines that feed to the bearing (and thus, it's ability to flow oil to the location) would be higher, rather than lower. The flow *through* the lines isn't what we want - we want flow through the bearings. (of course, what flows through the bearings has to flow through the lines first).
What I'm trying to say is that if large amounts of oil were able to flow past the bearing feed line and into the turbo and omp (as in the diagram), then that would lower overall oil pressure inside the engine, and decrease the flow to the bearings.
Out of curiosity, does anyone know if the renesis has that thread for the banjo bolt like in the diagram? That would be a pretty cool spot to measure OP.

Easy...just drill and tap the bolt...mines been like that for 3 ears....
Just make sure you don't impair the flow....

The FRONT OIL PUMP Valve assembly is taken from a 1972 Mazda RX-2, and also USED in the 1985 FC RX-7, if you look up the Stats (factory) they both say the Relief Valve Pressure is 156 PSI (Like the S2 RX-8, but the S2 does not use this valve location or part numbers at all).
The Part Numbers are (0839, which is 1972 RX-2 Model Code...OK..
0839-14-115 Plunger, Control
0839-14-116 SPRING
0839-14-274 NUT or Plug (with Oil Hole in the middle).......
The Series I RX-8 has the EXACT same Parts and Part Numbers above...
The ONLY difference is the Part Number for the SPRING (which can be critical)..
That part number is S1 RX-8 SPECIFIC...(ONLY Used for the S1)
N3H1-14-237 SPRING
Same for the FD RX-7 ALL the VALVE Parts are from an RX-2 except the SPRING is
FD Specific..
N3A1-14-273A SPRING
The S1 RX-8's SPRING would have to be either a lot weaker or shorter than the RX-2 or FC and Or FD to get such LOW Relief Valve Numbers..
Again...I will repeat...the REAR BY PASS VALVE is Mazda Part #
3648-14-250 (From the RX-4 and RX-5), and is used on all FC-RX-7's and ALL Series 1 RX-8's..
So, the ONLY Difference in the OILING SYSTEM between the FC RX-7 and S1 RX-8 by FACTORY PART NUMBERS are the Front Valve Spring, and the use of TWIN Oil Coolers (except Australia and Japan).....

There are no differences in parts (except the front valve spring and coolers) so let me see the differences in reference oil pressure:
The FB and FC pressure has to be 65-79,7 PSI at 3000 rpm, until the S1 Renesis has only 50 PSI at 3000 rpm. Same pump, same rear regulator, different front regulator spring and oil cooling system. Think about it!

I don't need to "Think About" anything mate...it's what I have been "Fecking " saying and posting in these 30 pages...your the one who should "Think" about it.
You keep posting **** we have already put up...

If I did not attached these...., and the rear regulator test-datas, we stuck at that the front regulator is only for emergency protection....but no matter...time will tell how stupid I'am.

Of course, I forgot about that you said the front regulator datas (that I found on two official Mazda sites) are wrong too!

I posted the Part Number info WAY back ( this does not lie) on the front valve was Way back, and you keep bringing up stuff that was talked about WAY back in this thread, an no one is saying you are stupid??
You, we are just going over the same stuff, every other thread page...

Every pages of this 32 contains minimum 1 new information. I think it is not bad average.

The printed data may be right, the questions is: how can we make this friggin regulators work as they should since nobody sees pressures above the 72psi mark with an unmodified oil cooling system?
Cheers!

Easily with shims, but before doing this I want to check the front regulator factory pressure datas by my own test.

Hey
Im from south africa and i have the rx8 hi spec .
I have been told to use the 15w40 oil in my ride , this however conflicts with what you have posted .
Do you advise to keep using the 15w40 oil in my rx8 ?

+30°c AND -30°c or you mean around 30°c?
If the temperature is around the 30°c mark you can use a 10w40 oil as well without problem i think. That's what i use even in a slightly colder climate.
