just trying to find out on it. closed deck h22 trying to calculate cr on a a stock h22. so if you know piston to deck please le me know.

 

Just found this. It should help.

SORRY DIDNT HELP. ANYONE ELSE?

 

If that didnt help you didnt bother doing the math.

 

mine was like .005" really close to 0.000

H22A4

 

well if i had the formula. i want thou of an inch so 1 inch is equal to 25mm is not good enough for me. that thing was very hard to read too.

 

oh i just looked again and i dont want deck khight if thats what your talking about. so, what i am looking for is not there...math or no math

 

It is usually about .005". I don't see how that helps you calculate CR though. btw:

deck height = piston to deck clearance + stroke/2 + rod length + piston installed height

this might help you with whatever you're trying to do...

cspeed's cr calcualor asks for it.

 

YOU NEED PISTON TO DECK FOR VOLUME REASONS. THIS IS CRUTUAL FOR CR READINGS. .005 SOUNDS WRONG TO HONEST. B SERIES ARE 10-20 I THINK. THE ENDYN PISTONS ARE SET FOR 10. SO 5 REALLY DOESNT SOUND RIGHT. ANYONE ELSE?

 

it is actually pretty accurate. i measured mine and it was a little less than .005. B-series are different.... as you can see some are .030 and some are .010.

I remember d-series being .000 or .001

WELL THEN TAKE APART YOUR ENGINE IF YOU WON'T BELIEVE ANYONE HERE. 3 PEOPLE HAVE SAID THAT IT IS AROUND .005" AND I TOO TESTIFY THAT IT IS ABOUT .005". H SERIES IS NOT B SERIES SO YOU CAN STOP THE COMPARISON NOW. AND YOU WERE GIVEN THE FORMULA TO GET THE THE DECK HEIGHT. IF YOU THINK WE ARE FULL OF **** THEN GO DO YOUR OWN RESEARCH AND STFU.

SO NOW STOP ******* TYPING IN CAPS IT IS REALLY ANNOYING.

you can go **** yourself. caps is on b/c i am at work and the system we run requires it. and the formula is not what i need. if you would read correctly than you might realize this. i dont give a **** about how tall the deck is. why are you getting all ******* retarded anyway. you are a fuckiung *******.

 

to everyone else thank you for the input.

 

I may be an *** hole but I think that it is disrespectful to question what 3 other people told you, in addition to that they gave you the means to figure it out for yourself, which you declined. I might ask for another opinion if a n00b tells me that it is like half an inch, but when 3 people with a combined post count of 2954 tell you that it is about .005" and you still won't take their word for it that is just not right.

That formula would have gotten you what you wanted if you would have spent the time to search for the other part specifications. For example:

Deck Height = 8.643" (source: Helms manual)
1/2 Stroke = 1.785"
Rod length = 5.630"
Piston compression height = 1.223

8.643 - 1.785 - 5.630 - 1.223 = .0057"
So there you go the compression height is very close to .005". 3rd grade arithmetic. That is stock but you would not need to know that anyway since Endyn told you the piston-to-deck of their pistons and more than likely the piston dome cc. If that is the case you had all the info that you needed and that makes the stock piston-to-deck worthless.

You also do not need to get angry at me because you feel that I do not understand the utility in knowing the piston-to-deck when calculating static compression.

If you cannot turn the caps off then say so since every other member of the Grammer **** Bandwagon would have jumped on you if I did not. Go ahead spell VTEC like this: Vtech. See if that solicits a response.

Anyway, be it as it may good luck with your build.

ok my fault that makesd sense but see, i am not using the endyn **** for this build. i see what your sayinig i needed it explaiined better. i apologize. thanks for the help.
