What system, style of kit you guys running? Also, what size hits?

I'm not using nitrous, however a few of my buds are. All of them run the ZEX kit. Most are running a 100 to 125 shot. A 150 shot is about all the stock engine will handle.

...yeah I wouldn't go too far on a stock 5.7, they are having problems without it.

What kind of problems? I just picked up a 6.1L Charger, waiting for the aftermarket to catch up to my mod addiction

The 5.7 with pressed wrist pins are holding up much better than the 6.1 floating wrist pins. Both have top ring land piston issues.

Damn, that's not (initially) encouraging, but I'm sure at some point this thing will have a big cube motor anyway

At what hp levels are these problems being seen?

The first 6.1 failure that I heard of, went while the engine was at idle. This was a fresh build with a factory shortblock. He sleeved the cylinder and rebuilt it to a 414 stroker and is now going with a direct port nitrous setup.

i'm spraying mine. i sprayed my hemi truck with a 100 shot for about 8 months no problems. I know several people with 2 stage systems with 100 shot each stage on stock motors that are fine. when you exceed that is where you're on borrowed time. I'm going to a direct port myself with a 150-200 shot on my 392
