I finally finished the intake horn.....good lord I hate grinding lol......all that is left to do is cut my output side intercooler tube to the correct length and install the intake horn . I hope to be able to get it all done tomorrow.

Added 2 more segments to the tube. I'm not gonna post anymore pics until the unit is done.....no need to bore you guys with the small stuff. I hope to have it finished by the end of this weekend

Sorry for the delay in replying. Here is a pic of the inside of the tube so far. I'm not done smoothing it out yet.

Welds cleaned up here.

Added 2 more segments cut at 4.5 degrees per end, short side cut at 9/16". I'm liking the radius that developing now .

Here is a pic of the unit with the welds cleaned up, inside and out. I'm thinking of cutting the angles shallower, 'cause I don't like those sharp bends it is making. It will require more cutting and welding, but its all good

After triple-checking some measurements, I ended up cutting off 3 inches of the tube. I have 2 segments welded to the flange now.

I'm not gonna powder coat it, but I'll shoot some flat black paint on it

Cleaned up the weld somewhat, and used a wirewheel to blow off the rust. I'll have more pics tomorrow .

I welded on a 4" long piece of 3" pipe to the flange. I'll end up cutting some of it off.....better safe than sorry .

The driveshaft is necked down to nearly the same size as my existing intercooler tube, which means I won't need to buy a rubber boot.

I am in the process of making my own intake horn. I'm too cheap to buy one, and I have the materials, the time, and the equipment to do it. I will also temporarily eliminate the grid heater until September or October. The intake tube will be 3" OD, made from driveshaft tubing from a 1985 Dodge 3/4 ton truck. The first pic is the flange that bolts directly to the intake manifold. The center hole in the flange is to make it easier for me to torch out the 3" circle......it gives me an easy starting point.

I have not heat-treated my pin at all, and only mild grooving on my pin......I think the grooving has more to do with the squared off end of the horizontal fuel rack pin that causes the groove. If I can can find a spare fuel rack pin to measure, I might be able to solve these grooving issues. My best friend has a 91.5 CTD with a stock fuel pin. I inspected his stock fuel pin on Dyno Day Mar. 17, and his pin was severely grooved. I'm sure the squared off end of the fuel rack pin cut the groove in his fuel pin.

You know guys, I would be willing to sell these pins for pretty cheap, say $50 plus 5 or 6 bucks shipping. PM me if interested

Here is the finished pin. Ran the truck into town earlier today. The new pin sure made a difference! The truck now wants to pull the front end off the suspension at a bit over 1/2 throttle. It was definitely a worthy project!
