I do this once in a while. I think it keeps everything healthy in my drivetrain. Anybody else? (The pic is a few weeks old - it was taken and I forgot to post. Oh and by the way, closed course, professional driver, etc)
I hit redline a few times a tank, about every 10,000 miles I will do 30 miles of hilly interstate and leave the transmission M5. My 1.4T seems to be prone to carboning up, probably from spending 98% of its life at less than 2000RPM. Sounds great after 30 minutes above 3000RPM.
I should add I topped off my tank and drove 100 miles in M5 once, still managed within 1MPG of my normal average when I topped off again!!!
I don't own a diesel at the present time ... but I did own a 1981 Pontiac Grand Prix with 5.7L diesel, non-turbo, and I used to floor that thing on a regular basis to "roll smoke" for people behind me that were tailgating! As for nowadays ... I frequently blow the cobwebs out of every vehicle I drive. (in an approved environment of course)
