Exhaust Temp , A/F MIX gauges.
Intake temp sensors pre cooler and post cooler gauges.
Map.
Knock voltage
Atmospheric temp
G force
Just about any parrameter you want can be measured and detailed depending on your wallet.
Best to do all temps (oil ,water ,exahust), oil pressure , A/F , IAT, map knock.

Take the sandwich plate off and work out which way the oil flows.  Out of the engine, into one part of the plate or the other, out through some hole, back through the other, etc etc.

good call!

Maybe I mis-read the diagrams, or I don't have a Greddy sandwich plate, but during the track session today, checking the temperature on the outside of the braided lines going to/from the cooler showed a 8-10 degree difference - but the line I thought was coming from the engine was the cooler line. I checked it numerous times just to be sure - a consistent 8-10 degree difference.

I'll put the temp sensor into the hot side - but I'll go back through all the diagrams to see how I got it wrong...based on the temperature readings the blank plug is on the correct side to tap for the new sensor (1/8 NPT tap on it's way via eBay).

cheers

I would say yes.  The central port is the return to the engine, which means the outer oil path facing the camera is dirty oil into filter.  The thermostat bypass is from the right hand port back into that outer path.  Otherwise, when the thermostat is working (hot), the oil will go out that side and come back on the left to the dirty side of the filter.  So your conclusion looks correct.

thanks GTSBoy - that lines up with my "updated" view of how the sandwich plate works and the temperature of the lines to/from the cooler...

My original understanding was incorrect.

Just waiting for my 1/8 NPT tap to arrive to get the sensor installed.

cheers

Mike

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
