WebNov 4, 2011 · 243s on an LS1 would put you at 10.5:1 which is what a stock LS6 motor is. LQ4 motors have a dish in the piston so they don't make as much compression. The LQ9 will be right up at 11.0:1 with a 243 head on it but that is because they have a flat top piston. WebThe high compression ratio leads to higher efficiency but diesel engines must be stronger, and therefore heavier to contain the higher pressure. This makes them more expensive. … chase young rookie season

WebIncrease the compression ratio - Higher compression ratios produce more power, up to a point. The more you compress the air/fuel mixture, however, the more likely it is to spontaneously burst into flame (prior to the spark plug igniting it). Higher octane gasolines prevent this sort of early combustion. WebApr 1, 2024 · The pressure should increase or decrease with the VCR commanded ratio change. The pressure change will be directly related to the static compression ratio that the engine can obtain. If the engine has a compression sensor in the combustion chamber you can match the sensor output reading against the pressure transducer reading.
