I took my intake plate off to see what I can do to help the air flow. As I soon as I got it off, I could see the head's design is terrible(5&6are really choked off). I'll probably try to mill out a tunnel ram when I have time. But for right now, it seems to be pretty obvious that if I rotated the stock plate end for end, that it should provide a much more even flow to all cylinders.

Have any of you that tried that? Does it make much of a difference?

 

y are they choked off? did you noticed any differance by flipping it around?

 

wat intake plate? the thing that the air horn bolts on to thats under the grid heater?

 

yea im pretty sure that thats the one that he is talking about

 

i was told that the #6 does run the hottest makes sense since its farthest from the intake

 

i would think that going to a twin ram would solve this problem

 

When you pull the plate off, and look inside the head's plenum. There's are large hump inside between cylinders 4&5. Looks like it's to accomodate a filter mounted to the under side of the head, but on mine it's not being used. The hump looks like it would cut the air flow in half to cylinders 5&6. On top of that, there's a sensor mounted directly above it, that looks like it would cause even more of a restriction. All that in the air flow has got to cause some uneven pressures and turbulence.

If I rotate my 12v plate 180 degrees (24v is a different plate,) then the inlet is over the hump, and the hump would likely act as more of a deflector routing the air more porportionately to the cylinders. At least that's what it looks like to me.

A tunnel ram or twin ram would solve it, but I was just wondering if anything was to be gained by just rotating the stock plate.

 

can u just swap it around or have to rig it up bc the tube not long enough?

 

i know of this issue and thats why my truck has a twin ram piece on it..... i wouldnt get it for 560 bucks but i got mine in a barn.... it was in a five gallon bucket... i kinda knew what it was an offered him 50 bucks without pulling it out and he said yes..... it had everything minus the 8 bolts and a gasket... deal of a lifetime

 

To rig the twin ram up do you gotte delete the grid heater or will it all swap to the new plate?? Just curious.....
