				84 mm piston comparison
			 
			Can anyone tell me the advantages of either piston crown design.  The taller (pointier) one seems to me like it would put a lot of the charge pressure on the rings.  Both are JE for a 2.4 Thanks 73 911 E     | ||

			no engineers out there that can tell my why JE changed the design?  Supposedly they have the same compression ratio. Chris | ||
