We know (and GM knows doubly so) what the strength and weaknesses of the hyper pistons are, and so we can work around that. My personal belief is: if you're serious about achieving such power levels aftermarket...don't be cheap about it - I want an engine that will last...and so if I'm gunning for 700+ hp, I'm replacing EVERYTHING inside...Extra cost? Yeah...worth the peace-of-mind? 100%.......but that all said....that's why I'm not gunning for those power levels. The LSA, as it is in stock form, is an absolutely phenomenal engine with no inherent "weaknesses". With a proper tune (is there any substitute?) it's highly capable of impressive power levels after-market. Want to go insane? Do it right, instead of complaining the manufacturer didn't do it for you (not you, trademaster, just in general) IMHO... |

I would like to get some info in regards to forged rotating assembly versus cast, or in this case powdered metal. Is it true that a forged rotating assembly is heavier than cast and therefore requires more energy to get the RPM's up? That is why manufactures do not typically used a complete forged rotating assembly.

The process to produce strong, forged parts is expensive. Forged aluminum pistons typically create a little more noise and tend to have greater expansion than hyper eutectic pistons (producing higher cold-start emissions). That the LSA was originally design for a Cadillac, any compromise to refinement/smoothness was unacceptable. |

Pace is high. Here's just one. http://www.crateenginedepot.com/62-L...17668C719.aspx GM Dealer....Rockenbach Chevy New LSA nonetheless....I don't know where they get the additional 30hp in the ZL1. I'm looking to repower my SS but I want a warranty....so I've been looking. |

With most FI cars, they die most quickly from one of two condition: a bad tune or too much rpm.
Either one is a recipe for disaster. Last edited by Big Top Gt; 10-24-2012 at 07:01 AM. |

For that kind of power, the starting point is either an LSX block or one of the other high dollar aftermarket blocks. Adding a couple hundred + hp to a stock engine, the expected result is a pile of broken parts. |

You can forge a powdered metal preform, or you can forge a piece of bar stock. The benefit of PM is lower waste (cost) and the ability to do cracked caps (which prevent 'walking', a leading cause of failure, without the expense of doweling the rod ends. The benefit of forging bar stock is increased density (strength). With these Forged rods, Pistons, and Crank in the 2013 GT500, a lot of aftermarket Mustang tuners, like Evolution Performance have made at least 1200 rwhp with a stock engine and upgraded supercharger, without any problems with engine breakage with the proper tune. That is how they have been able to run 8's with a stock 2013 GT500 with the stock engine. Any motor can blow up with an improper tune. |
