any one know what the c/r of the Supertech B-Series VTEC High Compression Race Valves are?...if you had 10.1 what would it be with these valves?

 

Depends. Are you going to have a valve job done when they are put in?

 

im just looking for an idea ..it's a bone stock b16 head..

 

Generally speaking,they should boost up compression between .2 - .4

What is CCed ? Co Cained? Or Coca Colaed or Comed Caca or Comet Cleanser,
Carrots Corn or is it Colon Cancer?? please help me .

 

.2 to .4 it good...i thought it would be like .8 or more. .4 is right what im looking for on the c/r to be add with out milling

 

CC means cubic centimeters or in this case, the liquid displacement of your combustion chamber in the head. With the head off and flipped upside down and the spark plug still inserted, you fill the combustion chamber with fluid until it's completely full. The tube they use to pour the fluid with is marked to show how much fluid you used to fill the chamber with i.e. "40cc's". Once you know the size of your combustion chamber it makes it much easier to actually calculate your compression ratio.

Flat faced valves tend to deliver around .2 - to maybe .3 bump in compression (GENERALLY SPEAKING). The reason why the question was asked if you were going to have a valve job done was because when you do, the valves will sit a little deeper in the head. This increases the combustion chamber volume and lowers your compression ratio slightly.

CC'ing your head is the only way to accurately determine your compression ratio (as well as knowing some other specifics), anything less is literally a guess.

 

I always thought CC was Closed Caption or Credit Card.
