I'm going to start looking into this 996 oil heat exchanger system + centre radiator. Dinkyhatchback just did the install of the centre radiator on his 987 and it seemed to go smoothly.A larger oil heat exchanger will pull more temperature out of the oil into the water circulation system. There is a model of 996 oil heat excnanger that is about 30% larger than the OEM Cayman. It does fit under the intake system. It also heats up the oil faster in the morning. That's what I am using. Motul 300V Competition 15W 50 is $287 for 10 2.2 liters cans on Amazon.
I have asked Brandon Clark from Slakker Racing Development to supply more info about the sandwich spacer on the spin on oil filter to have two plugs for the oil pressure and oil temp at the oil filter. I also asked for his best recommendation regarding the cockpit gauges and oil pressure/temp logging that would line up to what Slakker is providing on Rennlist. I do not intend to post these results, only to keep my own record as I will not have head pressure sensors only the filter sensor.
This will certainly fit into my 5 year car usage plan. No blowup from oil starvation.
I don’t have data on cooling yet but on my 987.1BS, I run a center rad, water with water wetter, dominator 15W50 oil, low temp therm,and have removed the condensers, fans, radiator ducts and fender liners. My oil temp typically peaks around 217F. Figuring out how much impact each of these variables has will be a fun project this summer in the Texas sun.Thanks for the writeup. I think moving to a 50W oil will also be a good move. It's a shame that FCP doesn't carry 300V in 5w-50 yet, but once they do it will be a good source to pick up 300V from.
Is the centre radiator an oil cooler or just another rad for the coolant? I'm fairly certain that it is just coolant - does this have a big impact on oil temps?
I did use a GlowShift Oil Filter Sandwich Spacer (before FSI put in the IMS Solution). It has 4 ports (1/8" NPT threads) and worked with an oil temp sender. I used a DepoRacing 4 fcn gauge for 2 oil temps, oil pressure and voltage.Currently, I have no oil gauges, but do have a LN spin on filter. Is there a commercial spacer that has the oil pressure and temp holes with threads that I can have installed along with the electronic gauges. What brand of gauges would you recommend?
your posts, @Apex1 , are like engineering lectures. good stuff. I also want to install oil temp / pressure gauges because of the bs oil level sensor which gives me a different value every time I insert the damn key. it is absolutely useless. Even if the oil level shows zero, I don't even worry about that because next time it'll show overfill. stupid POS. especially if there's no puddle under the damn car. Yes, I'm kind of venting here. this kind of stupid crap angers me from an engineering POV.I'm going with swirl pots rather than straight down tube to remove some air bubbles from the heads. Currently with my LN system, the idea was to quickly get the oil out of the heads with straight tubes as soon as possible and let the windage plate remove the air bubbles. Seems the Hartech system moves the oil around inside to get the air bubbles out while using swirl pots as well.
To bad that Porsche never put in the time/money onto research to get the correct oil pan on the M 97. They did correct the system on the next model though.
Hartech really changed the picture of price and use of the Cayman 987.1S. Once this oil pan gets through the install period and members have data to back up the investment of $1650, then we will start seeing the price of the Cayman/Boxster/911 (M 97 engine) go up substantially.
We still have rod bolts stretch and bore scoring to deal with though, so take it easy warming up the engine and no over revs for any reason.
I'm going to install an oil temperature and pressure gauge getting the info from a donut ring between the spin on filter and block along with the Hartach pan going forward.
