Thats why I said "most" diesels. There are some super-high performance tractor pulling diesels that use low compression ratios. IIRC, this creates more "space" for the incoming air and they more than make up for the low compression ratio with huge boost via retardedly large turbos.

I don't understand the exact reason why lowering compression and increasing boost allows more fuel and therefore more power without breaking stuff but apparently it does.
