ok, guys I work together with most famous engineer which has a responsibility for F1 pistons, which have a full support to MMC pistons (now is banned in F1).......I know what I do so please - no fairy tale
Hey David, these Gt3 engines, are these factory race engines? As far as I know gt3 engines from the factory are 12:1 compression. 14.6:1 would be sick!TDIMeister said:Unfortunately it's more complicated than that. There is no rule-of-thumb that can be applied for all engines, but rather depends on a lot of factors. The Porsche 997 GT3 engine has a compression ratio of 14.6:1 using European Super-Plus spec pump gasoline (!!!) Other race cars in the same class have found their optimal CR at lower values.
