Detonation is what causes piston and ringland damage (and a lean condition), but rod damage is from boost...plain and simple. To use a vehicle that has been around for a bit, know not to take boost - the Mach 1. Take 30 Mach 1's, all with the same blower kit, same fuel system and same tune....15 would be alive and 15 would not be. Some vehicles last, some do not last and it all depends on driver style, gas, and luck.
There is NO WAY I would ever believe any figure or word from a magazine....150 dyno pulls on race fuel, never seeing the street and who knows what boost...sure that will keep the motor in 1 piece.
I am sure the motors can take over 9psi, with an easy driver, not being beat on all the time and the right fuel system. It is proven that the stock fuel system is not good enough for the 8psi or so these kits come with from supercharger companies.
9psi is a "safe" boost level for the average 05 owner.

I'm only 340 at the wheels and I spin 275/40's like nothing
500, 600, 700 rwhp on the street...sure why not...don't plan on using all of it
