Calculating Compresson Ratio
I know the bore and stroke of the engine, but not the compression ratio. This is a running engine, i.e. heads on it. How can I figure out the ratio.

Pretty much impossible. If you know the cranking compression, you can get an idea of final dynamic compression.

I know the cranking compression.

That was a comical read...
There are, however, enough astute engine builders over on www.yellowbullet.com that can give you a basic idea what the dynamic compression is based on cylinder pressure. Specifically, the guys that do the 'pump gas drag' motors. Trying to squeak every last pony out of a given combination by maximizing dynamic compression without detonation. |

Whats New WJ?
The MAIN QUESTION Here is................................................ ..............? Did the Fellow Ever get His ARM out of the HEADER? Later G 8) |

What a read.... LOL
That writing craftsmanship was suttle but to the point..... I am still trying to figure out who road the best pony on that one... LMAO By the way, all of you forgot to factor in the 3/4 duration on that stroke and compression calculation.. When you get it figured out let me know what you come up with.... |
Guys, I can't help it I am still rolling over that one. My ribs hurt sooo Bad............ :lol: :cry: :lol: :cry: :lol: :cry: :P

Was a hard lesson learned for the kid repeating bad information like a parrot and then defending it. I bet his buddy caught hell over it.
