A quality hyperuetectic piston is good for 1000+hp guys - contact Keith Black and get the proof. relax.
The only reason forged pistons have any advantage is they can handle detonation better. So what - if you detonate that badly, the forged units won't last much longer anyway! There's no excuse for severe detonation on a modern EFI engine - that's what knock sensors and computer engine management is for.
NOS and Boost are fine with hyperuetectic pistons provided the engine does not knock/detonate severely... and that comes down to good engine building, good parts, good tuning - especially good engine management. They are not recommended for NO2/turbos etc because most guys push the limits and don't take the time to tune properly....
Many hot rodders are bozo's lets face it - they spend heaps of money on go fast goodies that someone told them over a beer works; they bolt it on without blueprinting, and then wind up the timing to see how fast they can get it to run - then wonder why it goes bang.. and cry over their next beer before going out and spending more money to do it again. Thats why manufacturers get reluctant to recommend anything short of full race parts.
Viper owners tend to be more discerning, and I'd expect any Viper tuner worth their salt would not sell a setup that detonated. No detonation = no problem for any likely street application!
I'd run hyperuetectic pistons anyday over forged units for a car that gets street driven a lot. Forged pistons operate at wider clearances that make them noisy. I'd take the lighter weight, the better seal/more power of the hyperutectic. Run em with a tight quench (around 0.040") in a blueprinted engine and you'll have a real crisp road weapon.
The real question about boost or NOS is not so much if they are forged or hyper but in their design -
are the crowns strong enough for very high combustion pressures, are the pins strong enough for high stress, are the top rings too close to the top to seal boosted power - that is more relevant - and I don't know as I've not seen an SRT10 piston. NOS Viper engines don't need high rpms - and high power at low rpm produces a lot less stress than high rpm power PROVIDED the NO2 is injected at correct ratios per load and rpm - and this comes back to good engine management including NO2 management. If the pistons melt - 99/100 its a bad setup/bad tune - not the pistons fault!
My guess is there is plenty in reserve from a factory piston for up to 10psi boost. If 10psi is a problem - I'd be pretty disappointed with Chrysler. Chrylser have a history of over-engineering and on a flagship performance model I hardly think their pistons will be maxed out at 1hp per cube. IMHO
If you want to run over 10psi in any non factory turbo/blown engine you should be using top shelf racing pistons in any event, so factory piston becomes irrelevant.
