again your setting the limit to 550-600 range..... we have already said that stock rods have gone above that.
that is your own opinion, and while you are trying to force your opinion on everyone else, i am stating the facts...... sure eagle rods are better than recondishioned stock rods, but thats the choice of the owner.... there are a lot of people that aren't "cheap" in anyway and use stock rods.
in my case... i would definately not call myself cheap but my shot peened, recondishioned rods cost me 200$ instead of 500$ for eagles, and im running weisco pistons on them and im currently making high 500's, and for 3 hours strait last night i beat the living hell out of my car racing Evo's, sti's, a cobra and various other cars, the last thought while i was bouncing off my rev limiter was my rods, because i built my engine and i have faith in my tuning
so my point is, you build your car and i will build mine, but dont tell me that i built mine wrong and set your imaginary HP limit on my motor because IT HAS BEEN PROVEN that they can handle it. and where did you get 30% margin of error? no offense but im pretty sure your pulling numbers out your ass. THE LIMIT AND MARGIN OF ERROR IS IN THE OWNER AND BUILDER OF THE CAR! but sure eagle rods ARE stronger, but if you detonate at 30psi from bad tuning it wont matter what rods you have, your gonna break shit
