Hi,
Finished the crank case tonight and temporarily installed a piston and cylinder to measure the deck height …
The excel calculation that someone on the board put together worked very well. For a 8.0:1 CR I calculated that I would need a 0.047 shim (which of course is not available).
Here I could use some help…
1. If I would use a 0.05 shim I would establish a CR of 7.94:1 and a deck height of 0.062 inch. The problem for this configuration is, that I can’t find a 0.05 shim .
2. By using a 0.04 shim (this seems to be available) I would end up with A CR of 8.12:1 and a deck height of 0.052.
3. By using a 0.06 shim (this one is also available) I would end up with A CR of 7.77:1 and a deck height of 0.072 which is probably to much.
I guess what I’m looking for is some advice regarding the CR and the deck height. I also would like to know if combining shims (0.04 + 0.01 …) might be an alternative that does not result in oil leaks. Maybe someone on this board knows about a place that sells 0.05 shims.
Thanks for your help,
