if you get a forged piston like a wiseco do they add power? i have one and would never get a different kind but i was just wondering
The simple answer is no. A piston captures the rapidly expanding combustion byproducts and forces the crankshaft downward to complete the stroke and put the power out the primary gear and into the clutch.
A forged piston is no more effecient at that job than a cast piston.
There are a few differences though. The cast piston doesn't distribute heat towards its outer edges as efficiently because of the orientation of the metal. That means you can build an engine with more power (hotter mixture and more timing advance) and the forged piston will "take it" better than a cast piston will. Also, when a cast piston gets too much clearance or siezes due to lack of lubrication they disintegrate. A forged piston will gaul the cylinder wall or break the piston skirt off clean instead of putting little pieces of aluminum into your crank bearings
I have the pistons but no scale. i don't sell drugs LOL
