good or bad tell me what you got?

i'm thinking of doing a small shot on my '93

i'm all about the juice but always had forged pistons and never thought twice about it.

i really see no reason a dry 75 will do any harm.

but i'd like to hear stories, not opinions, or a "my cousin knew a guy that had a sisters boyfriend"

i've sprayed 3 cars and know the routine.

i wanna hear about personal experience , thanks in advance

Your good to go on the hypers man , the pistons are not as bad as peole talk about all the time. In a NA combo they are actually better due to being lighter and having a smaller clearance between the piston and cylinder wall... People with the 05 stang run blowers and do 125 shots ... its all in the tune!

I have a friend who was spraying a 175 shot on his HCI 93 cobra with a stock short block. His car still runs great. I say its all in the tune.

93 cobra does not have forged pistons. I wish they did.

I was pretty sure they did not. I always ask my friend if I should spray 150 shot, and he responds "go 175 I did with my hyper pistons". Peer pressure

My old 357 with KB hyperutectic's got sprayed with a 150 shot a good bit.Never had any problems and that was spinning the motor at 6600-6800rpm's!

Edit: Most of the times we sprayed it thou,they were on the street.Couple times on the track.My opinion is though,if your racing it ALOT (like every week-end or serious bracket racing),it will probably eventualy break.I think that a stock rod will go befor a hyperutectic piston though,unless you go to lean or detonation.
