Performance

I don’t see why the average street guy wants to push CR level. 1 point is worth
about 4% hp so 300-500 hp is what a lot people are running equals 12-20hp.

To me pick your cam and gas you want to run and go with a CR that will work with a safety margin with that.

Some guys with experience running high Cr and pushing things to the limit that’s good for them but most will end up with pinging mess of an engine that they can’t figure out.

Most of us are not in highly competitive race classes where every last hp counts.
