Here is a technical one for you. Im building a motor and need to check
the compression ratio. My Burette is broken but it is only a double
check.
Lou are you out there.

In the old days it was the ratio of cylinder swept area divided by combustion
chamber capacity and squish area on the top of the piston. You will need a
burette or similar. Sorry, I can't remember the area formulas. What have you
changed to alter the c/r?

Thanks Lou, I have the calculation but just need to know the volume of
the head chamber.
Recon includes last os pistons and head skim, I just want to check the
figures obtained from the net.

You can fill the combustion chamber with water up to level
with the head. Suck the water back out and weigh it. 1gm of
water = 1cc Will work as well as a burette but requires
accurate scales to 0.1 gm or better.

If you sucked it out using a graduated pipette you would not need the expensive accurate scales.

Great idea David, one problem though. The head is away being ceramic coated and
I would like to do a dummy build on the bottom end this weekend to check
heights etc.

Why are you concerned about c/r, unless the heads been shaved considerably or
the piston crowns are different to stock, an overbore of that size shouldn't
cause you any problems with excessive c/r.

I thought you couldnt use water to CC a head as it
has a funny skin effect at the very top of the chamber
making it innacurate. Engine builders use an alcohol
type solution instead dont they??? Good excuse to
break out the Vodka bottle from the cupboard!

You're talking about capillary effect and you're right if you need to
calculate the precise chamber capacity. But if you just want to equalise the
chambers, water would do.

A good night's sleep is letting me think a little clearer - why even use a graduated pipette when you already have a graduated buerette to measure the volume that you put in in the first place. Isn't that what chemists use when they are carrying out titrations?
