Are hypereutectic pistons good for nitrous?
Are hypereutectic pistons good for nitrous?
Hypereutectic aluminum will typically have between 16-18 percent silicon in the alloy. If adding a power adder like nitrous, turbo, or supercharger, we recommend avoiding the use of a cast or hypereutectic piston.
What are hypereutectic pistons made of?
aluminum alloy
A hypereutectic piston is an internal combustion engine piston cast using a hypereutectic alloy–that is, a metallic alloy which has a composition beyond the eutectic point. Hypereutectic pistons are made of an aluminum alloy which has much more silicon present than is soluble in aluminum at the operating temperature.
Which is better Hypereutectic or forged pistons?
Hypereutectic pistons are stronger than more common cast aluminum pistons and used in many high performance applications. They are not as strong as forged pistons, but are much lower cost due to being cast.
Are hypereutectic pistons lighter?
Registered. Light is usually 400-450 grams for a 4″ bore piston, A Hypereutectic will be lighter than most Forged pistons in its price range.
How much HP can cast pistons take?
Stock cast pistons will limit you to 5800rpm, but cast pistons will hold more than 500hp. It is good to 7000 for forged pistons. It all depends on your goals and what you need to do.
Whats better forged or hypereutectic pistons?
Do you need a cast or hypereutectic piston?
The choice between using a Cast, Hypereutectic or Forged piston is dictated by the application. Forged pistons may not be absolutely necessary in all applications. However, the minor additional cost of a forged piston can save your motor from disaster in a marginal situation.
Can you use nitrous on a hypereutectic piston?
Ring end gap is a big deal on hypers too. Some brands like lots! Nitrous needs even more. If the ring gap isn’t enough when the heat is thrown to it from a nitrous hit they will butt, gall and lift a ring land off. It’s just my opinion but I personally would not chance a nitrous shot with hyper pistons.
What’s the difference between forged and hypereutectic pistons?
The main difference between hypereutectic and forged pistons (both are made with the same 16% alloy of silicon) is in how they ultimately fail. A forged piston will go plastic and deform (usually blowing out the top of the piston).
What kind of silicon is used in cast pistons?
Cast, Hypereutectic or Forged Pistons. Any silicon that is added to aluminum above a 12% content will retain a distinct granular form instead of melting. At a blend of 25% silicon there is a significant reduction of strength in the piston alloy so stock hypereutectic pistons commonly use a level of silicon between 16% and 19%.
