Stillen supercharger and engine fail. :(

Had upgraded pulley and belts, at 8lbs was making 409whp which is where the phail happened. Have previously dyno'd 490whp at 12lbs. Having z withdrawal already.

Hope everything works out for you. The other thread about a used Vortech SC unit failing and now this.

Just curious, why did you take it back down to 8lbs? 490whp is impressive for 12lbs for the stillen kit. Do you know what your tuner set your target air fuel ratio at? and how aggressive was the timing?

Nah, not looking at 10k not going that rich. I'm hopeful to get out for 4500, realistically before its all said and done and I'm driving away should be no more than 6k and that's giving ~1k+ for incidentals.

And no, I don't know the exact tune specs. I do wonder though if if having an aggressive tune and then dropping the boost from 12 down to 8lbs wasn't somehow responsible.

And there is the problem right there.

I'm not seeing the problem. Plenty of people run high boost. Im at 12 lbs too. No problems at all.

My question is has the tune been altered when boost is varied between 8-12lbs

And 12, imo, is in the upper range of what I would consider a reliable setup with stock internals. Maybe you are lucky, who knows. All We know for sure is that someone else had rod failure at the same boost that you are running.

Someone also mentioned another failure, I wonder what boost he was running...
