Working out gear ratios.

[1 Mugen racer]

Has any one got any links they can post for me about the understanding and working out of gear ratios.

I'm so confussed any reply would be much help.

Thank you.

Maybe someone else can post links. When dealing with any gear set divide the driven gear by the drive gear. It's just like a ten-speed bike (the larger the drive gear is the faster it'll go AND take more tork to go)

An example with a spur and pinion might be a 15 tooth pinion driving a 90 tooth spur gear has a ratio of 6:1 and a 20 tooth pinion with an 80 tooth spur is 4:1 and will go a lot faster (higher gear)

Okay i understood some of that. My eyes just go blury sorry.

How do you work out a top speed of a car from the cogs and rpm then?

How do you work out what gearing is best?

Sorry i probably sound terrible. I just don't have a clue to what is a good gearing.
