Boy, this is really eating at you isn't it? If I had an aftermarket intake of any kind and was happy with it, I wouldn't even bother reading this thread. But you keep wanting someone to prove it's performance improvements. You're just hoping that it does nothing so you can be assured you didn't throw your money away on your intake. Otherwise, I see no reason for your interest on this mod.

Are you the forum police all of a sudden? It really seems to be eating at you that I question this mod. You seem to want to run me down for asking the question. What do YOU have to gain from this?

Your right, I'm interested in seeing if it really does any good. Not because of what intake I run on my truck, but to finally answer whether this is a worthwhile or even safe mod. I guess I'm just being a **** for trying to look out for others.

 

hwm3,

Have you dyno'd your truck yet? It seems you have spent around a grand in the performance department. I think 40bucks to get on a dyno to see YOUR gains would be the best thing, but wait did you dyno in stock trim ? The point is the relationship between the two, the DWV modification costs less than the dyno pull, where as spending 1000 dollars and then another 40 to see results is justifiable. If you havent dyno'd your truck dont tell someoneto dyno theirs.

 

As I posted in the other thread that has since dissapeared I'm still curious as to why the DWV mod that is so bad for our engines isn't causing any CELs where the supposed best intake for our truck is throwing CELs left and right. If the threshold is so too tight like Mike claims it may mean that the AF1 isn't causing any problems even with the CEL but wouldn't that mean the DWV mod is staying inside Ford's extremely tight limits making it closer to stock?
I'm probably not understanding something properly but if Mike (or anyone) could explain it I would appreciate it. Learning is fun

 

Wow! Are you worried you spent too much on your $325 intake? It sounds like it to me. If you weren't worried that you spent too much, you wouldn't be concerned with this $6 mod. Get over it.

Just to be fair, I going to tell everyone something. I had the DWV mod on my truck until last week. I took it off and put the stock tube back on before taking the truck to the dealer for a couple repairs. After installing the DWV then going back to the stock tube, I HONESTLY cannot tell any difference. It may be that the difference is only felt at WOT...I have never driven my truck that hard. Regardless, while I can't tell a difference at all, I also do not think that the DWV mod will hurt anything at all. The MAF on the truck meters the amount of air flowing through it and adjusts the amount of fuel accordingly. That airflow is determined by how much the TB opens up. The more it opens, the more airflow there is. If the stock tube restricts the flow that the TB is calling for, this is where the DWV would improve performance by allowing more air into the TB than the stock tube would allow. Either way, the truck adjusts to the airflow that is present.

 

You are correct and the stock tube and paper filter will flow 7 times more air than the TB can handle that is a fact thus all these mods are a waste of time and money!!

 

Yes i totally agree. Its just bragging rights

 

Is this true? If so, then why do so many people pay over $300 for intakes? I can see a need on older intake types...but our intakes are true cold air intakes from the factory!

 

I've got an appointment for Thursday.

 

Well, did you?

 

No need. Someone else had already proven that the mods I did provided gains.

The ONLY reason I'm headed to the dyno this week is to datalog and get the tuning optimized for my truck.

 

I had the DWV mod, too, and removed it today and went back to stock. I honestly can't tell a difference, either... I wanted it to make a difference, but if it did it's too subtle for me to notice.

 

Ok, i',m getting in here late but what Mike said has REALLY got me worried about the Gross Lean Condition. I have the CDC Shaker and i know that it flows some serious air at highway speeds. I wonder if i have a gross lean condition? It is my "understanding" that if the filter setup is not changed then the air metering electronics work fine. Doesn't the DWV mod keep the same filter/air metering setup? Would it not trip another error code that my 1714 will pick up? My other concern is that Mike has mentioned some trucks not being able to hold the commanded A/F ratio. I guess i need to get a A/F meter and go test it and datalog it.

 

We all understand they provide gains in some way, but the real question is "how much. That's why we dyno stock because various engines have various outputs even from the same plants. You can't take a claim and say it will produce "X" amount of horsepower. Also we don't know [and cant trust] if manufacture claims or those selling the products are FWHP or RWHP. This is why we dyno stock to find out if the money we spent was well worth it.

PS: I am not starting a war with you.
