to get to the normal temp mark with the heater running on such a mild day. That is running off immediately but RPMs at < 2500 25-30 MPH for the first 2 miles, then 55 MPH but no hard acceleration or over 3k RPM until fully warm.
Verified this morning after the Boxster sat over night as I went for a light bulb for the Honda. I'm conscious of it as it only gets to that point as I hit the nearest store so I know I don't open it up till on the way back.
Sounds like there is quite a variance out there! I have a Innovate Motorsports OT-2 which can log the coolant temperature. I assume that will be more accurate than the dash gauge?
Sounds like I might be ordering a low temp thermo soon anyway!
