Thanks, makes sence to me. I work at a CNC mill shop and was going to try and make a new plate and horn very simular to the Wilson, before I saw their's. Now I think i'll just buy one.

My idea was for an oval shaped intake horn and hole in the plate. Flattening out a piece of 6" SS pipe and builting a plate to weld it to for the bolting. Then taper things down to a normal diameter horn for connection to the cold pipe. I've been tossing around the idea of even making a new injector line for #2 so as to make the biggest possible opening, maybe an 8" pipe.

But at $500, the Wilson is hard to beat. I know I couldn't justify my time and material and come out less than that.

How is it that there was no hp gained? I totally understand the idea that there was no more fuel added, but at the same time you should be getting more air, so some of the wasted fuel, or black out the pipe would have been burned, therefore producing more hp. Not trying to dissagree with ya, just trying to get my facts straight. I really like what the Wilson has brought to the table in inovation. But to only gain tq is a bit mystic. If you gained tq, it would have been from more air sooner. If your getting it sooner, you should have also been getting it later, so i'm a bit confused.

Straighten me out Richard. Am I totally wrong here?
You will see a slight HP gain at peak HP about 7-10, when the motor is turning 2500 rpm it is already de-fueling so there is not gain. Diesel are as you pointed out...no fuel no power period. From about 2000-2400, the gain is about 25-37 hp depending on too many variables.

No milling! It is remove and bolt on. The thing is you have to open the fuel system to install the botoom plate.

Yes, the plate was designed to remove the overhang that the factory plate leaves exposed on the head. This prevents the air from hitting the overhang and making a 90 degree turn into the airs path to the head.


My results are not typical. I gained about 20 hp overall from the intake. My EGTs were down 300 degrees @ WOT and the smoke at WOT is about 40 percent less. The turbo comes on a little quicker too.I do run a SB so they are laggy as it is.

300* drop in egt's and the only difference was this intake?

Erik, lets look into doing this! I also want to see the results and you guys did a great writeup on the other intakes available!

Yes, that's what I PERSONALY experienced on my truck and my truck only. I do not want this to be a blanket statement. You can expect to see a large decrease in stock trucks also. We put one on a friends truck and his egt's were down almost 200 degrees at WOT if I remember correctly. This was about 6 or 7 months ago. I know there are others running the intake that you can read about on the other forums.
