[QUOTE="cobraCMDR, post: 1873161, member: 25210"] Yeah I think we should all be honest with ourselves on this one. We know what the mod does and well...if your running high RPM for a matter of time and making full boost when the computer might be trying to kill the boost and possibly making A/F and timing adjustments......it just might lean out the top end and make enough heat tooooooo dare I say it, melt or cause the telflon cyclinder wall clearance to be too close and waste the piston? Not for nothing, but does anyone know the actual clearance? is it tenths? Thousandths? Millionths? How much heat does it take to expand the piston faster than the cylinder? Can you compensate by a better heat exhanger to keep intake temps down? Maybe running the engine richer up top might help prevent this? Maybe it is time to look up the melting point of teflon........maybe an oil cooler would help with this, or a bigger oil pan? I don't know about you guys but I find it hard to believe that SVT would design an engine that was not capable of running high speeds for a long period or time especially 30 seconds. Or maybe we should all just buy stock in JE pistons and make a few bucks off our piston replacements...... :( [/QUOTE]
