HEUI is definitely an issue wrt to performance...but unless you want to run a solid/no coolant (7.3L) head, going to common rail isn't a gain.

if you want to run coolant in your 7.3L heads (ie, our CNC ported), you'd still be short on CFM compared to a stock 6.0/6.4L

it's a real nut kicker.
How would a set of stage 2 ported heads from y'all compare to stock 6.4 heads?

The guys who are using P-pump set-ups they have developed log style intakes, with individual runners, take a look at Smokin Addictions engine build.. Now that is way out of most individuals range of nature, but I've wonderered for quite some time what would some runner style intakes do for head flow and remote mount the turbo (much like the 6.5 diesel) and see what it does. I think some custom log style intakes would drastically improve head flow on a 7.3..

I wondered the same thing about how they achieve more flow for the mechanical setups.

Funny you mention that elrodalexander, that's my plan is to remote mount the turbo to passenger fender well. Much like Duramax setups. Then try to come up with a large capacity intake manifold. I've just finished removing the manifolds today. I'll be ordering the flanges and tubing soon.

Have y'all ever dyno tested the hp gain going from stock heads to your ported heads?

Technically, it won't change cfm in the head at all. But it may force more air through with boost, you would still have to clean up the flow IN the head.
