Thanks guys. I'll try to update the list on Monday when I get more time.

-installed at 34,000
-since then 38,000

Only thing I've hurt is the stock 4l60e, other than that shes still going strong.

Here are my results, I ran the piss out of it.

- Type of Forced Induction (Turbo/Supercharger) = Turbo 76MM on center
- Boost Amount / RWHP = 16-17# 580+ rwhp
- Miles on the car when FI installed = Unknown
- Miles ran since FI has been on the car = 10,000
- IF you broke the motor, list what was broken. = Ringlands 2 Pistons

Yep, the car was dyno tuned and was about 12.0 AFR iirc. Pump 93 octane at the time. I have a suspicion that my failure may have been caused by possibly water getting into the engine thru the mecham hood and in thru the bypass valve on my old setup the heat extractor on the hood funneled water right onto the race BPV when i would get caught driving in the rain...

I have an E85 tune I run every now and then and bump up some timing...don't know hp/tq numbers on e85 safe to say over 550rwhp.

are you on meth injection or just strait pump fuel?

I was bored, so incase anybody needed it, I re-arranged it so you can go by kit (alphabetical), boost within kit, and if they broken at the end of their respective kit list:

So the people I want to reply in the thread are ones who have ran boost on a stock bottom end (pistons, rings, rods). Even if you broke something in the motor, still post up. Post only cars you own(ed).

Here is the format I'd like to see it in:
- Type of Forced Induction (Turbo/Supercharger)
- Boost Amount / RWHP
- Miles on the car when FI installed
- Miles ran since FI has been on the car
- IF you broke the motor, list what was broken.

Still haven't made it into the list, but I KNOW the motor is toast! Probably a broken ring land like most folks, but I won't know for sure until I take the car in to replace the motor. Currently spending what feels like a fortune on a new motor in the worst economic environments of my lifetime. I guess I'm just doing my part for the betterment of the country . :thumb:

BTW - This is one of the most useful threads I've seen in a while - thanks for starting it! If I had a better understanding of the limits of a stock block I probably would have lowered the timing a bit to reach "safe" hp levels.
