Difference between a pulling truck and a street truck?

mercredi 25 mars 2015

Quick question: Why do pulling trucks smoke so much while on the track?



Many will say that excessive smoke from a diesel points to higher than desired EGTs and can lead to engine damage.

I've heard others say that pulling trucks dump extra fuel into the cylinders to cool them.



So what's the real reason? I want my trucks to run clean on the street and I don't think that smoke means power but I always get the argument regarding pulling trucks and how much they smoke and still put down big numbers.



Your thoughts?
