Nishant,

If you intend to use data you have collected over the internet to
support your Mechanical Engineering Final Year Syllabus, I recommend
that you stick to published data from sources like SAE, NASA or AHS.
Referencing data, opinions or conclusions from individuals personal web
sites is not a good idea.

Do your own research of from reputable data sources and then draw your
own conclusions.

Good luck,
