Are Keith Black pistons forged?
These pistons are made from forged 4032 alloy that has an 11% silicon content. Pistons are formed in a forging press an then fully machined.
Who makes silvolite pistons?
UEM
Currently, UEM manufactures the Silv-O-Lite OE aftermarket piston line, KB Performance Pistons (including the motorcycle division), and The Claimer Performance Piston Series.
Who makes ICON pistons?
Icon Forged Pistons | UEM Pistons.
What is ring end gap factor?
Multiply bore size x ring end gap factor. Example: For a naturally aspirated street engine using a cast piston with 4.000″ bore, the top ring end gap would be 4.000 x . 004″ = . 016″. The second ring end gap would be 4.000 x .
What happens if the piston ring gap is too wide?
Now, if the gap is too big, the engine will have too much crankcase pressure, have a ton of blow-by, burn oil, and lack proper cylinder sealant. Different engine setups need different piston ring gaps and it’s mostly dependent on how much fuel is being burned.
How much horsepower can hypereutectic pistons handle?
roughly 600-650 horsepower
Hypereutectic (Cast) Aluminum Pistons Best suited for up to roughly 600-650 horsepower in normally aspirated engines.
What are the benefits of hypereutectic pistons?
Although not as strong as forged pistons, hypereutectic pistons offer increased strength that raises piston reliability at a lower cost. Hypereutectic pistons also don’t experience as much thermal expansion as forged units, which means they can be mated to their respective cylinder bores with tighter tolerances.
Do changing pistons increase horsepower?
How much power? The percentage increase in displacement from a bigger bore piston will deliver an equal percentage increase in torque and horsepower. Second, aftermarket performance pistons can be ordered in a higher compression ratio than the factory piston.
Are cast or forged pistons better?
In the casting process, the alloy molecules are free to settle where they please, creating a random grain structure, and opening up the potential for weak spots. This is why forged pistons are fundamentally stronger than cast.
How can you tell a cast from a forged piston?
Look at the underside of the pistons. The unmachined areas of a cast piston will be somewhat rough looking (not as rough as an aluminum intake manifold but simliar) where a forged piston will be smooth.
