Not really sure how the whole grid heater discussion got started but it's not the topic here. Thanks for the info on the intake it was helpful. Oddly enough you were the only person to accually answer the post with information requested. Matbe sone one else will see it and comment on the intakes. Thanks again

 

The hole point of the extra discussion was that the emissions grid causes the second most restriction in the intake system, first being the EGR butterfly.

Get rid of everything EGR related. The grid can be deleted by simply unbolting the elements from the housing.

 

Good to see forced induction whargoul still trying even though he's been banned from many diesel sites. On subject I run the Lazarsmith ir intake advantages where getting rid of the bathtub on the side of the head and better airflow

 

Thanks for the info. Is any one else running something besides the H&S or the IR from Lazarsmith?

 

There is no benefit to an aftermarket horn on a 6.7 if the grid is deleted. The 5.9 only had benefit because the bolt tubes obstructed airflow.

 

im still running my grid. but i did the h&s intake horn and it made a noticeable difference in spool time. just sayin

 

i have a cfm on my 12v im not sure how cfm is with the 6.7 but my egt's never really come above 1200 romping on it and it spools up quite quickly really nice i think!

 

I took my stock horn off and removed ALOT of excess casting material, if i remember correctly about 1/2" head side, and 3/4" fender side, i also smoothed out casting lines inside and tried to make it as free flowing as possible. The only difference i noticed was the boost read-out on my blackmaxx claims 0 psi at idle now, used to say 4 psi. I believe this means it helped reduce back pressure, But not enough to "feel" anything. ( I'm too cheap to buy an intake horn)

 

93/250, the reason I'm interested in the air horn is it removes the EGR when you replace it and you save money on the delete with a small benefit or at least I believe there is some benefit.

 

Very true, if i would have known more about "deleting" a 6.7 when i ordered all my delete stuff i would have gone the same route as you are intending to do.
