Hyper Pistons in 1992?

[Henceforward]

I know that 1993 was the year for hyper pistons, but did Ford put them on Mustang GTs in 1992?

I was trying to find some info, but everywhere says 1993.

i herd they were in 92's to

yep, in late-model year 92's.

How do you tell the difference between a hyper and a forged slug? My engines sitting in the garage so i'm just curious what I had in my 92. I'm gonna guess I had forged because when i had my dry n2o kit the a/f was 18:1 on the dyno and it didn't blow up

My 347 will have probe forged slugs

black oil pan is hyper and grey is forged.....just hope no one switched pans on ya

Which months were late 1992? My car was built on 07/92, where would I fall?

And are Hyper pistons bad for any reason under 300 HP?

About the only time I've heard of hyper pistons being much of a problem (on street machines) is with poorly tuned forced induction.

from everyone I have talked to they all say the hypercrap is just as strong as the forged

its just that if you get a real bad detonation or something the forged will give a little(but still be damaged, you might make it home) but the hypers will shatter(leaving you stranded)

I would venture thats late 92 but check your pan to make sure. They are fine for 300hp and even more as long as you dont have any detonation. Hypers are more brittle than forged and tend to have chuncks or holes in them when detonation occurs vs the forged that usually just get dented up a little bit.
btw thanks for the dancin monkey

my stock hypers are doing fine with the S trim.

I did get a dyno/tune to ensure happiness.

I bet the block gives up before the pistons.

PS, I just put on the smaller pulley.

hyperutectic pistons are not ment for any type of nitrous use, nitrous increases cylinder temps and a cast piston is very likely to meltdown, if you have the motor out go get a cheap set of Sealed Power Powerforged pistons, theyre less than $350 and a good moly ringset is like $90, if its a good motor dont worry about machine work (though i recommend it) just get standard stuff and put it back together. cheap insurance.

i was told hypers and boost dont mix not sure how tru that is

insurance for what a crappy tune..

im done, hyper pistons will turn to dust if you even say boost in front of them.....

Grey Pan! Forged! And I know it wasn't replaced.

My '92 GT is an early one..03/92, and it has a grey pan and forged pistons. I know for sure because I had to have one replaced...

I got a 93motor in my car, suppose now a 93 motor. It has a grey oil pan and it is a H.O motor. So prolly I got a early 92 instead of a 93 motor??? What do u guys think? If so that would be awsome lol

88SN, when things are not known to be OEM, i would not read too much into the color of the pan.
and 93TT, thanks for posting that - i had never known how accurate that info was (pan color), and forgot about it altogether when i posted).

I put keith balck hypers in my 347 stroker...and acording to their tech they hold up fine with a good tune and 10psi boost making over 500hp. They have several employees using this combo.

No problem, I've read it a few times and it has held up for every 87-92 amd 93 I've seen so Im pretty sure it works
