This is a really interesting vid. I've never seen a direct real-world comparison of a turbo vs a naturally aspirated version of the same tractor. These Indian dudes really love their tractors! There are a lot of Indian tractor vids on youtube.
The results are quite interesting. I imagine that though it may seem trivial to some of us, if you are disking/plowing a very large field, that 100 RPM advantage ads up to some time savings. I'd love to know what the fuel cost difference is, and whether the additional fuel used is mitigated by the time saved.
