[QUOTE="97tc, post: 13865707, member: 113292"] I'm sorry that you lost your engine, that's never a good feeling. As an engineer this is cut and dry. You exceeded the design parameters of a mechanical assembly and it failed. You could have done more to support the increased stress or load. For example you raised the redline by 1000 rpm and didn't even do a simple valve spring change to support the increase in rpm. As rpm goes up the force on components goes up by squares or on a logarithmic scale and small things such as oil temp, pressure, windage, piston to wall clearance, ring gap, valve float, octane become much more critical. Factor in the extra heat and force from no2 that causes piston expansion. Did you increase your cooling capacity or ability for the engine to rid itself of the extra heat generated by no2? Said in another manner I wouldn't beat my worst enemies engine the way you treated yours. The engine should have been properly set up for 8 grand and no2. Proof of the pudding here is that Ford went to a different piston/rod assembly for the Boss 302 and a higher valve spring rate, larger radiator, oil cooler to support the increase in Rpm to 7500 and a moderate power increase. I purchased a track pack car to get a head start in supporting an increase in power, Proper Planning Prevents Poor Performance. I don't see the tuner having a lot of liability here. [/QUOTE]
