I couldnt tell you the specs either, but it makes the vehicle feel like you got a signaficant vacuum leak. On the vacuum side with a max of 14, I see between 5-9 when the Insight is in its "eco" or using its vtec to make the atkins cycle. Also the piston pin and rod and or crank are offset too to lessen friction and the piston skirt is layered in teflon.
