01 ws6,m6,ls6 bottom end,241 heads.
- 67mm sts set-up
- 10.5 psi, ebay fmic,meth / 550 rwhp,600+ trq. on high boost /meth
- 80k on car/@60k on ls6
- car has 102k/20k of that boosted
- motor still runs great/ doing a front mount set-up now.
a/f never went over 10.5:1

Here are my results, I ran the **** 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
- 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 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:
I am wanting to make a comparative list of how long the LS1 stock bottom end has lasted under boost and eventually make it a sticky. Generally I see everyone say 550rwhp, I just want to see how valid this statement roughly is.
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.

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.
