Nitro cc

[Chris Down]

I know this is probs a silly question. But the numbers associated with engines. How do they relate to actual cc. For eg a .28 Mack star, a 25 savage a 46 savage a 15 18 this or that; what does it mean!! ?

When you see .10, .12, .15, .18, .21, .28, .30, .32, etc. that's CI (cubic inch) . When you see whole numbers, that's CC (cubic centimeters) usually.

.15 ci = 2.46 cc( round to 2.5)
.21 ci = 3.44 cc (F3.5 was a .21)
.28 ci = 4.59 cc (round to 4.6)
.30 ci = 4.99 cc
.32 ci = 5.24 cc

The Nitrostar S-25 was a .25 ci. They kind of went rogue with that. lol!

Both maths and math are shortened forms of the word mathematics, which is the study of number, quantity, and space. Math is the American variant. Maths is the British variant. Luckily, there is a very easy way to remember maths vs. math. Maths ends in the letter S, just like the river Thames in England. If you can link this bit of British geography to the British word maths, you should have no trouble remembering the usage cases for these variants.

Oh oh another perfectionist. Say Maths 3 times fast , you sound like you have a Lisp, Stick with your British Variant , This is MERICA DUDE . LOL

By the way Math doesn't makes sense it make Dollars if you do it right , see if you can handle a little humor.......
