Surprised the IR cross ram did so well. I wonder if principally its the straight shot into the head port that makes for s super efficient air flow. That said, would a IR intake with a more conventional up/down runner (i.e. turned up to 90 degrees) make similar power?

Bob, it is really hard to beat an individual runner manifold for torque, so it didn't surprise me that it did well.  And I think a set of runners that looked like a conventional injector setup would make more power.  The runners on that crossram are not really very straight as you go to the outsides of the manifold; in fact runners #1 and #8 are curved pretty good.  An upright runner could be made much straighter because they wouldn't have to cross over other runners.

Thanks for the detailed reply!

On the IR intake ,the torque dip between 3800-4500 would that be a function of stack length?
I remember back to the Drag Week SOHC where the street set up had short stacks for air cleaners and long to race.

I know test test test….

Thank you for the incredible effort!

It is absolutely a function of stack length, or more precisely a function of the length of the intake tract, from the inlet opening of the runner to the intake valve.  The length of the intake tract will determine the sonic tuning function, and leads to the peaks and valleys in the torque characteristic of an individual runner intake.

The short stacks I used on the SOHC street setup at Drag Week were only short because I needed them to fit under the hood, they weren't designed that way for any performance reason.

I spent 10 minutes searching but didn't find anything.
How do the new heads' dimensions differ from stock heads?
Could one of the new intakes be 'adjusted' to flow into a set of stock heads? How far off are the air/fuel streams?

{edit}. I did find this:

Quote
On the FE Power heads the intake port is raised nearly 1-1/2" over a factory medium riser port.  It is higher than a high riser.  The valve cover rail is also raised proportionately.  This allows a very generous, smooth short turn on the port.

In addition, the port is straightened out.  Stock FE intake ports, except cammer and tunnel port ports, all hook towards the center of the engine and aim the intake charge at the cylinder wall.  My heads straighten the intake port so that the cylinder wall is less of an obstruction to flow.

Also, the valves in my heads are moved from the stock location.  This again gives room for a better chamber, and better flow into the cylinder.

Look at the link below.  The info is somewhat out of date now, but you'll get the idea.

I just gotta say, could that IR intake look any f***ing cooler?!??  Clearly no.

Wow some great manifold design and fabricating there Jay!  Could you make a tunnel wedge like that last version to fit a 351/427 9.5 deck Windsor?

I could.  But I don't want to; FEs only for me.  Sorry  ;D

 Very interesting to see how all the intakes performed. I’m racing, so I’ll be going for the dual four high rise, but the fact that you can bolt together these parts with lower single four or tunnelwedge style intakes and make over 800hp is astonishing.

First let me say thanks to Jay for letting me in on the testing phase..  As mentioned I am a dyno groupie.. You might even say I am the dyno monkey for Jay's operation.

There was so much data gathered in the last 18 mo which is absolutely essential to making the right decision on what parts to produce.. I would go as far as to say that for FEs, Jay Brown is the pre-eminent development engineer. Exceeded only by Ford itself.

The numbers posted are awesome for an engine platform written off by the racing press, and there will be more to come.. These heads are as cast.. Wait till the ported versions get tested..plus very little camshaft development  has taken place, so most likely there is horsepower there. This engine could make more power with a bump in compression, and finally 600 cubes might be in the works so you could see a 1200 hp NA Fe before the decade is out. Put that in your Mustangs and smoke it  lol  Now if we could just get it legal in the stock classes .

Thanks again Jay.. Hope I get invited back for the next big thrash.

I am willing to funnel some cams into the R&D process.  It helps me as well, not only in camshaft design, but I have/will have multiple builds involving these heads.  We made great gains from the first swap and I think we can fine tune from there.
