Rounding out this series we come to the final step, what compression ratios can be expected from head and block milling?

Sergey Kiselev of www.LadaMoscow.com has supplied these reference charts to help you dial in your Lada compression ratio. We have been able to convert them to English for ease of use and one chart is supplied for the 2016 Series and the 21011 Series, be sure to reference the correct table for your engine.

Please keep in mind that these numbers are purely mathematical and are not firm recommendations for your exact combination. Please speak with your engine builder or machinist as excessive milling may cause issues with the camshaft timing architecture, head gasket leakage, or failure of the block/cylinder head.

Proceed with caution before milling for 12:1 compression ratio!

If you are curious about how much power gain there is from the various Compression Ratio, David Vizard has published this easy to use chart. It is simple enough, simply take your current compression ratio across the top row, and then look down the column until you find your new compression ratio, the cell on the chart will tell you the percent increase in horsepower over the old CR.
