Title: Machining heads for higher compression Post by: leec on January 22, 2012, 22:50:55 pm Hi guys,
My heads have a cc of 52, I would like to flycut them for lower cc and hence higher the compression ratio (think I got that the right way!) How do I know how deep to cut for each cc?

Thank you, knew it would be a simple answer ;D Lee Title: Re: Machining heads for higher compression Post by: TexasTom on January 23, 2012, 00:27:47 am Depending on the shape of the combustion chamber, it IS possible to calculate the amount of cut needed beforehand ...
I've done it many times. The problem with water is working around and estimating for the deviance in measurement considering the meniscus. TxT |
