240Z Turbo Posted May 4, 2006 Share Posted May 4, 2006 Finally got some flow specs for my RB26 cylinder head from Endyne. Head specs as follows: HKS 280 10.2's IN/EX Camshafts (thanks Matt) Fidanza Cam Gears Ferrea Valve Springs/Ti Retainers/Seat Locators 1mm Oversized Inconel Exhaust Valves 1mm Oversized SS Intake Valves Endyne Port work and combustion chamber modifications. Below is the blurb I was given about the way the head flow is measured. The orifice measurement method we used to generate these sheets is the same as very conservative Superflow standards at 28". It should be noted that I use our air-flow transducer to develop ports, and it's CFM readings are between 15 and 20 CFM higher than those I've attached. I've found over the years using our element nets better-performing heads, but the public likes Superflow numbers for comparison sake.

240Z Turbo Posted May 6, 2006 Author Share Posted May 6, 2006 It had been recommended that we remove the squish area, but since we are using a custom piston top configuration made from taking molds of the combustion chamber we can take advantage of the squish area to create mechanical octane(combustion efficiency).

RB26powered74zcar Posted May 7, 2006 Share Posted May 7, 2006 What does HKS 280 10.2's IN/EX Camshafts equal in inches? Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted May 7, 2006 Share Posted May 7, 2006 10.25mm is about .400", so 10.2 is just under that. That's why we only flowed my head tho that height. My cams are 10.25, or .400" Quote Link to comment Share on other sites More sharing options...
