When I got some free time, I will add a sensor to the other port. Getting bored watching fuel temps before and after cooler anyway.

That port is a 1/2" NPT threaded port. A plug for it can be had at any good hardware store. You can get them with a 1/4 NPT port in the center of it for the temp sensor, but if your sensor has a 1/8 NPT fitting (like mine), you will need a 1/4 NPT to 1/8 NPT adapter to screw into the bigger port plug to get it to fit.

I do like the killerbee coolers (you cant have to BIG of a cooler when running a thermostat), but my only concern is using the available space with air flow that we have. If I run a cooler the size of the radiator, but 75% of it is blocked from air flow, it doesn't do me any good. This is the exact reason why I'm going with the cheaper more cost effective twin cooler set up that will have 95% exposure to the air flow. If there not enough,,,,,well I will just have to back out of it slightly. However, I'm convinced it will be far better than the setups were running with no cooler at all.

my local hardware store had a 1/2 to 1/8 adapter in stock!

back to the op, defi temp gauge installed on the top of the oil filter housing

Cool Jeremy. Helps to not have to buy extra fittings if you don't have to. Good to see your reading your temps. Let us know what you find and under what outside temp and conditions. I'm using a "Shindy digital water temp gauge" (same as the oil temp gauge but without all the brass adapters for the oil pan hook ups). I got it from amazon (a few other places carry them too though). It has velcro with it and attaches just about any where.

Michael or anyone with aftermarket turbo/s that think oil temp is a problem have you done any UOAs? Stockish Dmaxs are pretty easy on oil. I've ran a dino oil up 15K before it started to shear. Thats better them most diesel pickups.

Trivia - I've run 3 engines that were primarily oil cooled (no water):

VW - Contrary to popular belief, the oil cooler does most the work.
Husky 510? desert bike. Not only oil-cooled, but no oil pump. Go figure.
Suzuki GSX1100G - Oil cooled monster bike. Stupid amounts of power everywhere from idle, manners of a Cadillac, and even handled pretty damn good.

That is all. You may resume your regular broadcast.

I did a report in the "oil temp with twins" thread and using stock power and unloaded truck. I didn't like my results. No UOA yet but working on getting some trucks tested. Are you running any oil bypass? I'm running my purifier and don't plan on changing it anytime soon. I'm going to have the samples run at every 25K intervals as long as I can on the same oil. Oil does NOT wear out if you filter it properly (it's been proven full flow oil filters don't cut it, and GM even did a study on this and found out there motors could last at least 7 times as long if filtered properly), it just deteriorates from over temps. What do we have to loose from cooling it properly in case it does get extremely heated (only takes once). Partial breakdown of the oil is issues I want to avoid as well.

AHH! Thank you for the input Mr. Pat. My XR650R is a dry sump and the oil is pumped through the aluminum frame and this is what cools it. It can get pretty warm. Key is though, that it is getting out side the motor to cool.

Just out of curiosity, what if a guy tee'd into the port where the feed line to 2nd turbo is ? What temps would you get there?

Ya I have a FS2500 bypass, but once I'm out of my filter stock pile I will most likely sell it. I just don't see the point. Pushing theses engines like we do they're never going to fail from wearing out.

Here is a link to my UOAs. My truck is stockish with a 2000us tune for DDing. Very little towing nothing over 7K. The 3rd post has several of my past UOAs the 3 oldest are of Delo400 dino and the newer ones are of Rotella Syn

I had an oil temp gauge well before the HTT was installed and EFILive was purchased.

With the stock turbo and Edge Juice it would easily put the oil temps above 260* while towing a medium sized load.

....and people wonder why LB7 injectors fail so often. :rolleyes: Engine oil "cooking" them sure doesnt help.

I cant agree enough after seeing my oil temps going to 230 and climbing with the truck empty (hauling nothing except me), stock program, holding the speed limit and EGTs driving up a hill in the mountains.

And there it is in BOTH statements. Just to clarify though, if this is not thought to be needed, by no means worry about it. This is info for those that believe there is benefits to oil cooling.
