Or maybe the peak cylinder pressure is just a bit too much for the pencil rods?? Try an FE3 rod/block/head, barely longer stroke, much bigger bore, much stronger longer rods, perfect. Where is Rob's sig when you need it?? :-)

Stephanies pics were of my car. I thought Matt was a nut for having a blown motor. Shows what happens when you think! 17lbs of boost bent rods 1 and 4. The pistons looked fantastic, just a nice hue of bronze with minor carbon build up. In fact, they are on there way to the Domican Republic now! I kept #4 rod for posterity's sake. It was shortened by 1/8 an inch and slightly twisted as well. I got Wiseco 9.0's and Eagle Rods from Alamo Autosports and now I can really turn it up. Woohooo!

Im running 275hp at 15psi on stock internals and have no problems. Pauls been running The Machine at 300hp/15psi for well over a year now with no internal problems and in october he turned it up to 311hp. Still going strong.
You can't run a car at 13psi with a 12.6 afr. Thats way too lean. Why wouldnt you just tune it for 12.1 afr instead of pushing the car more?

Hmm... I did not think it was that aggressive in boost. It is a few degrees retarded from what Paul said he was running in the famous timingz thread from what I can tell. It is much less aggressive than the map Ben posted, and less aggressive than several others in that same thread.
Anyone else think my map is over the top?

I thought you were running Ben's map. Whoops. Your map is very conservative in low boost. I run 5* more than you around 150kPa, but in high boost, toward redline, you run more timing than I. Curious, about what RPM did the motor go boom? IE-4k at the onset of full boost or were you about to shift and then pop?
