"With all the discussions about the filling and exhaust cycling rates and CFM, there are rarely any results that indicate the differences in cylinder pressures at combustion time.
I'm not talking about static comp ratios but rather the pressure in the cylinders WITH mixtures at different AFRs and DCRs.
Obviously there must be a difference would have the same torque.
Ex: What is the difference in combustion pressure between a motor with 9:1 static CR and a 7.5 DCR and a fire breathing 13.5:1 at a 8.5 DCR? :x
I'm really interested in differences between the setups and potential pressure differences.
Gas, Alky or Nitro?
Not considering boosted apps, just N/A for now.
TIA"
