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

MotorvateDIY

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.

Rear Differential Oil Temperature Sensor:


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:
