Bone stock 2011 Mustang GT goes 12.7@112...

Nope, hyperpathetics and powdered metal rods. Supposedly the parts are safe to about 8000 rpm, but have similar limitations under boost that the previous 4.6s had. The oil squirters might help curb light detonation under boost though.
 
We owners of Hyperpathetic (good one Ben!) piston/powdered rod cars have discovered it is NOT the piston that is weak, it's the ring gap is too tight. Open up the ring gaps and the pistons hold together well under boost if the tune is sharp.

The rods do fine even at elevated hp levels.

Yeah, but who cares??!

If you push enough boost through ANY engine, you MUST build the bottom end.

Even the import fanboyzz' most worshipped stock engine/block/bottom end (2JZGTE) had it's limits, albeit fairly high (as were the Termi's bottom ends

).
It's when they start their 'telephone game' BULL about completely stock 2JZ bottom ends holding 40psi, and 1600rwhp that I say, "gimme some of what you're smoking"!

If I had a '10 GT, I would just keep it NA, pull as much as I could out of it in that form, and spend coin to lighten it (and even further improve the already great handling) as much as I could.

If I had a '10 GT, I would trade it in on an '11 GT.

Seriously, I was never a big fan of the 3V and a monster just took its place.
 
I'm seriously considering ditching my plan to get a GT500 and just go the GT route. The savings in insurance can buy a lot of after market parts.

I'm just amazed that in from 2001 to now, the Stock V6 today has the same power as my 2001 Cobra did, and the new GT Coyote has the same or slightly better HP than my 2003 Cobra. The GT is a bargain basement HP steal!

What would you guys think the cost would be to upgrade the rotating assembly of the V6 and then put twins on that set up?

What I really want is a sleeper V6, with the SVT suspension-handling-brakes package and wheels.....and the 6 speed from the GT500. Cheap as heck insurance, then build the engine up from there.

Hyperpathetics? Is that what people who suck at tuning call them now?

Huh...considering the 2JZ-GTE ran hypereutectic pistons too. Ring package is a big factor though and tuning is always THE critical element.

No, it's what people who like a little extra margin of safety call them.

Margin of safety against what? Bad tuning? Sure...already called that. The only thing that keeps hypereutectic pistons from becoming more mainstream is the cost of making them. They are stronger, can be made to more exacting standards, and can be adapted to specific racing conditions with regards to material properties. Same goes for powder metal rods. Only big companies can afford to make these pistons and rods and they only make them for the OEM's. Though I'll tell you, some of the hardest working pistons and rods in racing are hypereutectic and powder metal forged. Also, a lot of people who knock hypereutectic pistons and are running forged pistons are often running hypereutectic pistons and don't even know it.
 
yeah, the new gen Hemi crowd has finally discovered that it was the tight factory ring gaps blowing pistons under boost, NOT the piston design.

Go forged, expect lots of noise and emissions. I have 2 forged piston motors in my stable and one of them is a 8000 rpm monster roller motor that can be a bit noisy on first start, but quiets down in about 30 seconds as those expensive slugs heat up a bit.

Margin of safety against detonation. Detonation isn't necessarily brought about by a bad tune, it can happen with bad gas, low fuel pressure, and any other number of variables. Why do you think Ford used/uses forged pistons in the Lightning, GT500, Ford GT and 03 Cobra? Factory tunes on these vehicles are ridiculously conservative, yet they still wanted the extra margin of safety. In the real world, [censored] happens.

They are stronger


They are harder, which is precisely why they don't provide the margin of safety a good forged slug does.

That's funny, I know dozens of cars with forged pistons, and those from good builders (Modular Performance, BES, etc.) make zero noise, and are every bit as quiet as their hypereutectic counterparts.
 
Yup, all the '87 to '92 Mustangs were forged slugs, as were the Lincoln Mark VII LSC's. They were not noisy.

The Termi stock internals were good for 1000HP. Ford went seriously overboard there.

GM uses hypereutectic pistons for their boosted offerings. Ford doesn't. Hypers are not "bad". They simply lack the ability to handle imperfect situations in the cylinder the way a forged slug can.

Exactly
 
so if you follow the logic used we could assume the Hyper piston users have more confidence in their tune?

Seriously, any true car guy is going to want seat time in one of the new Coyotes!

The great thing about a Mustang is that you can make it your own.
