no, I have a blog about racing and some stuff , but as to making things go faster

20 odd years of reading/studying and working in the trade ( talking to people much smarter than me )

but there is a torrent

internal combustion engine fundamentals by J b Heywood

a bit academic but ... its a start

Get a engine that is easy and cheap to rebiuld , Cg XL125 etc

measure , think measure again and ask LOTS of silly Questions

there is a computer software that you program the engines specs and it will act like a dyno and produce a graph ( its not too bad ).. i think its about 160 us dollars

but you can try different things such as valve lift openings etc

its a usefull guess thats all
