Webb19 nov. 2024 · Depending on the type of course, boost is limited between 19 and 21.7psi with a push-to-pass boost of 24psi. While no manufacturer shares their actual compression ratio on its IndyCar engine, the expected compression ratio range for these engines is between 11.5- and 12.5-to-1 according to most sources. WebbThe compression ratio (CR) is defined as the ratio of the volume of the cylinder and its head space (including the pre-combustion chamber, if present) when the piston is at the bottom of its stroke to the volume of the head space when the piston is at the top of its travel (‘top dead centre’, tdc). Typically, petrol engines have a CR of 8 ...
