WebHow much HP affects compression? The generally accepted gauge for adding compression is that one full point of compression can add between 3 to 4 percent power. So, if an engine is making 50 horsepower and we add a full point of compression (from 11 to 12:1 for example), this could potentially push the power to 51.5 horsepower. WebFeb 6, 2024 · Compression is good for making power if the engine doesn't get into detonation, but at first glance, this high a ratio seems excessive for an iron-headed engine on 91-octane. However, with the big-overlap cam, cranking compression was only 182-185 psi, well within Sherman's comfort zone. http://johnmaherracing.com/tech-talk/what-effect-does-compression-ratio-have-on-bhp/ iphone repair in houston
