Pistons, Clearances, Compression Ratios and Fuel

[Rasteirinho]

Well, 11.9 is no problem if you have a good cooling and lubrication system.
Also good bolts and bearings should be fitted.

Because the temperature and pressure inside the combustion chamber will increase a lot compared to the original values.

Well, if i had the time i could calculate the new pressure and temperature... lol

However, also the ignition timing and fuel injection will have a big impact on the pressure and temperature values. So a good mapping is also requested.
