[QUOTE="TARM, post: 1428053, member: 578"] you are coreect on air as thats the other half. To be honest oj the HP the real pro are looking at engine dynos as it removes all the variables. What happens if I start to remove resistance from the reast of the system. I would say a solid 1200 on the engine dyno would prove out the goal. The hp factors I uaed were based on the typical ppump per cc estimates 2.3-2.5 per cc. But CR are 3hp/cc. most 7.3 have fit in that range but as you get the fuel higher up in the bane, improve flow with cams, head porting work, roller rocker lifter etc it would move that ratio up. Thus you can make more on the same oil as its getting more out of the fuel. [/QUOTE]
