2018 M550i xDrive

MarcSigouin2017 · 05-30-2021, 12:35 PM

Hello Folks,

Just got my 2018 M550i upgraded with bigger turbo's, catless downpipes, Stage 3 Tune.
Does anyone know what the average coolant, oil, transmission temperatures. I have taken it down the track and I do not get any errors from iDrive or from Protocols. Just want to know if I have to leave it cool between passes (which I have been to be safe) . Any help is greatly appreciated!!

I'd love to more about any track or dyno results.

I would expect that you would get heat soak so cooling down between runs is probably mandatory with stock cooling. I did a lot of research on the Audi 4.0TT platform and heat soak was a massive issue especially with bigger turbos. 1/4 mile was fine but 1/2 mile heat soak would pull timing and power.

Sorry, forgot that...Pure turbos

The latest track results range from 11.5 to 11.6, respectively 119 MPH and 120 MPH

Are you at a high altitude? I'm only stage 2 and running 11.07@125. I'm in Illinois.
