- 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

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:

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 .

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.
