I use two SCSI magnets on my oil filter and two that curve around and surround the oil pan drain bolt.

Obviously you may be seeing higher PSI at WOT, the majority of Owners here do not race their car, the Renny in most cases 'lives' around the 3-4000 RPM.
Well, didn't i send you the video showing the pressure?
If so please forgive me and i'll send it again! With a stock cooling system (twin coolers, stock filter, stock oil pan) 5 bars is the highest pressure i see!

Like SCSI hard drive magnet you mean?

You are doing a pretty good job of convincing me Ash. Is there a magnet you recommend? Or just a plain old magnet that fits?
If you want convenience buy the Filtermag.com one, S1 owners go for HP250, S2 Owners SS250, the HP250 is too thick and won't fit on S2's.

Or if you want to save money and make your own and just place these magnets together (this is all Filtermag do, exact same magnets)...

10 (Qty) will do just nicely!

Yeah they are way stronger than regular drive magnets but obviously harder to come by. I actually took them out of some brand new drives that came in a server I bought but were pretty much useless because they were only 36GB.

But the Filtermag is the way to go but I have bunch of drives laying around so it's no big deal.

Thanks! And yeah, geez, the price difference is drastic. $22+ for the magnets raw, $56+ for the pre-made.

Yes, I wish I knew of that site before I bought the HP250, had to pull it apart to ONLY use the magnets so it would fit my S2 filter location...But now works a treat..

Just line up the loose magnets, they will stick together fine, I put tape on the back, so it is a little easier to "slide" off the filter...

Isn't that a morning flag in the morning?
5bars= 72.5psi or so! I mailed you the videos

Yep, that is the bar...

Got your one Video, Giorgio...

Sent you an email...it is a bit blurry, which one is your OP guage?

We don't see higher pressures because we have the factory oil coolers-pipes system. This long and narrow system restricts the pressure so much that the rear regulator (78-92,5 PSI) has not affect on the max oil pressure. Actually the rear regulator does not get higher oil pressure in the factory system like 72-75 PSI.
The front regulator determines the max oil pressure in our system

PhillipM and 9krpmrx8 has modified oil cooling system, so the rear regulator determines the max oil pressure in their modified system.

Yes.
First : e-shaft pellet plug in (related to max pressure when the oil cold but the water gauge shows warm engine)
Second: Less restrictive oil cooling system. Like single cooler systems.
Third: Shims under the regulator's springs.

I think.

Yep, that's what i was thinking, it would be cool to see what a stock single oil cooler rx8 shows on a gauge.

Good luck removing the e-shaft thermal pellet without removing the engine

Ok, I find the same datas on the newest European WEBMESI (only for official services) site.

• An oil pressure regulator has been adopted on the rear side housing to release oil when the oil pressure is 538-638 kPa {5.5-6.5 kgf/cm2, 78.0-92.5 psi} or more.

Actually I have this data for long times, but my oil pressure gauge shows only 74 PSI max pressure, so I beleived your datas are right. But the single coolers systems justified the european (78-92,5 PSI) datas.

Otherwise, if this data would not be true, what would be the explanation of the single coolers 90 PSI max pressure, in your opinion? The rear regulator can't control the max pressure? It is impossible. There is so much difference between 74 and 92,5 PSI

Thanks! That will be a hard one. Maybe it won't go without removing the gear box, to reach the flywheel.

Firstly now I'm trying it on a removed engine.

OH..OK what you guys only have the one OC, like S1 Australian cars?..

Sorry, when you say European I think UK, the S1's in UK have the 2 Oil Coolers!!..
Yes, my EPC Confirms it...How does one work that out???
Australia is far hotter than the UK, we get one cooler they get 2!!!..STUPID!

ALL S2 or R3 here have 2, except the Autos..still only 1.

So that explains the higher readings if you only have the one cooler in Europe.

Giorgio, there is your answer, 1 OC = higher pressure, 2 like in the USA and UK... = lower readings..

As has been confirmed by 9K, Mazda *Fecked* up for USA and UK models by not upgrading By Pass Valve for 2 Oil Coolers...with the same Oil Pump and valves.

EDIT:, So, anyone who has installed the SECOND OIL Cooler, you should upgrade the B P Valves.

The FD RX-7 has 2 OC, but a different Rear By Pass Valve assembly and larger displacement Oil Pump.

these are good infos, wonder how long it will take for mazmart to step into production with the remedy bypasses!! as you can see my oil pressure is very stable up there but still lower than it should be. how can we see this engineering flaw in a modern car? it's a freaking huge difference, 15psi between a 2 and a single oil cooler model...
did anybody remove the OC t-stats? do they see an increased pressure? maybe that's another restriction that should be considered!

The only thing is that test isn't particularly accurate as they're testing it with air, which obviously has vastly different properties than motor oils.

I'll try to introduce the kit next week (In time for Christmas).

I agree, but as a reference about a 35% increase.

Yep, potholes with the occasional bit of tarmac in between.
Bloody fun though.

There's a reason most car manufacturers have specific suspension settings for the UK, everbody thinks they're the next F1 driver...
