1st Gen Hood Stack Build

[Relentless70]

Elbow flange has been cut out.

Flange is tacked to the elbow in this pic. I ran out of carbon dioxide for my MIG welder....otherwise I would have welded the flange all the way around. BTW, I'm at a perfect 90 degrees now. Tomorrow I'll run to McCall and pick up another 5 lbs of dry ice so I can finish all my welding on the stack.

For those of you that use a MIG welder with carbon dioxide, you can substitute dry ice instead of taking your bottle to Norco or Airgas. I do the dry ice method because the closest Airgas or Norco shop is 140 miles away. 10 lbs of dry ice will give you 700-800 lbs bottle pressure, and costs $15.

I just finished welding up the flange to the elbow, and I had to add a piece of pipe to the leftover pipe I purchased from NAPA. If it weren't for the rust on the additional pipe, you would not be able to tell I welded another piece to the leftover pipe.

Winning!

The elbow and pipe have been welded together, welds cleaned up, and painted in this pic.

 

[Relentless70]

Well, here it is installed. I'll need to make a flapper for it to keep out the rain and snow .

looks good! might be a stupid question, but does that whole in the hood allow you to open the it all the way?

I sure can Texas. In fact, I cut the hole too long

I got to post up that I've seen this in action now... Hell yeah Relentless truck looks rather cool with a cloud of black rolling over the roof!

I appreciate the kudos Mike . I saw ya coming from the other direction, and figured why not drop the hammer a bit. Was in 5th gear, just goosed it a couple times. A buddy of mine that lives in New Meadows got the same show lmao. Went to his house today, and he was truly impressed. I had to twist my brother's arm to drive the truck to town last night(sarcasm). Never thought a 38 yr old guy could giggle like a schoolgirl LOL!

This hood stack not only looks decent, but my EGTs are about 50-75 degrees cooler, and it spools like crazy. I backed off the wastegate 2 turns over the last couple days, 'cause it would peg my 30 PSI gauge in almost nothing flat, even in 5th gear. I think I need to invest in either new head bolts or studs . Bummer.

Got home from my buddys place in New Meadows, and found a crack developing in the elbow of the hood stack. Took the pipe off, re-welded it....no grinding the weld this time. Installed the pipe, and added a cheesy 1/8" thick x
1" wide brace that bolts to the exhaust manifold and is hose-clamped to the stack. I'll come up with something prettier in the near future.

I backed off the starwheel 2 turns tonight, 'cause she blows a bit more smoke than I'd like. Had to do a bit of cleanup on my fuel pin too....there was a groove that wearing into the fuel pin. I backed off the wastegate another 1/2 turn also. I'll be running the truck tomorrow, and I'll let you guys know how it goes .

Do you carry a coffee can for when it rains now? Lol

 

[Relentless70]

Funny that you mention the coffee can....yes I do carry a 3 lb coffee can in my truck now ROFL! I'll carry it until I get the flapper made for it

 

[Stangshcky12]

I couldn't imagine the mess that would make if you didn't cover it lol

 

[Mopar1973Man]

I had to spread this around a bit...

Got 224 HP/571 TQ. I need a better lift pump. Power drops off like a lead balloon at 2500 RPM.
