what do you consider an acceptable act? 28DegC with 30psi?

*Following are not actual figures, just examples*

on a 7:1CR engine this 28 becomes 196DegC under engine compression

on a 10:1CR engine this 28 becomes a 280DegC under engine compression

spontanious combustion of the fuel occurs at 220DegC

so the air needs to be made cooler BEFORE entering the cylinders, ie 22DegC at least.

now being as people running 7:1CR can have "problems" with detonation it becomes alot more problamatic once the CR is raised.

boost is "free" power, why waste it? high CRs are used to eliminate lag, plus you can only build on what you start with, and a high CR starts higher. its all swings and round abouts. do something, cut back on another. classic examlpe of our lecture on lateral weight load, do we load the car balanced when static, or is the track more suited to an asymetric load when static, ie are there more left corners than right. you give something up for another.

as in, high CR with same boost as low CR needs a bigger cooler to stop det, but at what point does the size of the cooler have to be so big to stop this that the lag is so big that it becomes pointless?
