I flycut my pistons a while back and I have been thinking about sticking my wet kit back on the car. I usually sprayed 50 or 75 on it and would NEVER go over 100rwhp if I put it back on the car. Is anyone spraying their stock flycut pistons? If so, how much and have you hurt anything?

Will I be safe with 100 octane, rich tune, and 100rwhp wet on my flycut stockers?

I fly cut both the intake and exhaust. Spraying a TNT 150 shot, put a few bottles through so far. Pulled the passenger head last night (due to a few Comp R's collapsing) and it looked fine. Did a leak down test before I pulled the head, all cylinders looked good.

u shouldn't have a problem. theres ALOT of meat on ur pistons and they usually blow thru the sides anyhow

That's nice to know I'm just hoping it will be ok with nothing over a 100 shot. Hell, I may not go over 50 or 75 now.

Whatever you do, don't flycut too far and then epoxy your pistons (Do a search on it...good reading, lol). I guess as long as you didn't cut that far you are fine!

i've seen ppl shoot 150's on there stock flycut pistons.. and like i said, the side (the ring) gave way

No need to run rich, just run right on. Unburned gases can be pre-ignited in the flycut pockets. as long as you are properly tuned and do not have any hot spots from carbon build up, you'll be fine.
IMO I would run a bottle of RedLine fuel system cleaner on 1 full tank, a few WOT runs and that should clean anything up.
