Just curious. I personally dont believe our cars are detonating all the time or even most of the time at moderate boost levels (or at all at 10lbs and under) . Cast pistons wouldn't last a month under daily detonation. I do believe its possible to have high rpm detonation without any means of detection without telemetry but dont think thats why people are blowing either. I also know are engines are one of the most detonation resistant engines out there by design and practice(just take a look at the semi wedge head and nearly flat top pistons or spend more time at neons.org with 12:1 pump gas NA 420A's). The question is at what point (hp level, boost, on your kit, whatever) does detonation really become a concern that needs adressing (in the form of timing retard) assuming efficient enough intercooling and adequate fuel. Right now I dont think anyones knows for sure.
