The "Other" oil temps we don't know...
 

Hey Everyone,
I just wanted to share some "behind the scenes" work being done at MotorvateDIY Garage.
I have often wanted to know how hot does the manual transmission oil get... AND how hot does the differential oil get..

Well...Now I can monitor manual transmission oil temperature AND differential oil temp AND data log them with the current time to a SD card.

Manual Transmission Oil Temperature Sensor:

Motorvate Designed & Built (Arduino Uno based) differential and manual transmission oil temperature display with max temp and data logging to SD card. (oTemp is outside temperature)

Why bother doing this?
Well, I wanted to see how much these oil temperatures increase during:
• A long highway drive
• Driving in traffic
• Drag racing
• A few pulls on the dyno
• A track day (HPDE)
ALSO...
Will the temperatures change when I put in fresh RedLine 75W90? The differential currently has 3 year old non-synthetic Nissan 80W90 differential oil.

Drag racing is scheduled for next week. The HPDE is booked for October.

All the results will be shown in a future episode of Motorvate's DIY Garage:

When I did my diff up-grade. An OS Giken diff, Z1 diff cover, SPL diff bushing, MA Motorsprts diff cooler. I installed a SpeedHut Diff temp gauge.

It takes about 10 miles of driving to start to see the diff temp gauge moving up. Driving 9 hours at 80 mph to ZDayZ. The highest temp I seen was 260F. Trackday was 270F. I can turn on the diff cooler and drop my diff temps below 200F after about 10 minutes.

Can't wait to see what you get for the tranny temps. I thought about installing a tranny temp gauge.

Welp. I might as well buy a diff cooler now, bc as soon as this data comes out I'm gonna be all "must be colder.'
