Don't forget, I also use an electric water pump so my routing may be different than what you need.

But, it's starting to take shape. I'm back in school so I won't be able to go buttholes and elbows on it, but I am giving myself Thursday afternoon / evening and some of Friday to work on this thing, so that's when I'll probably update stuff.

Using the radius of the piping to set the spacing between the turbine flanges.....

And here they are being held "sort of" in place. Tom was holding them up for me and with the two of them together it's a bit awkward. They'll actually be slightly farther back and rotated clockwise (as you're looking at them).....

The ones I'm running now are Exergy 250% over with 2 Floor-It mod'd pumps. Even running the big single (Garrett 4718 - 88mm) I could drive it without blacking out the planet if I didn't want to. The main problem was the single was so big that it made no boost below 2000 RPM's. I just pretended that part of the RPM range didn't even exist. It woke up around 2300-2400 and wasn't REALLY lit until 3000 RPM's. Trying to get the truck moving without having to go heavy on the fuel with no boost took a little finesse.

Now, if I just let it eat, there wouldn't be a mosquito problem in North America for a decade.

With the fuel I have now, the truck wont make much more power than what it has. I'm just out of pump. It sits right at 1551 hp now, but that's about all it's got. It'll have enough air 1600-1800 hp and it has enough injector for that, but the pumps are pretty maxed out. If I bring the duration any higher than what I run it at the track the pumps start dropping pressure. Oh well, just need to add another pump. lol :doh:

As for compounds or triples.......how much power do you want? Once you start getting really big with the primary is where you want to look at the triples. Two smaller ones are usually cheaper than one big mofo.

Originally Posted by cumminalong (Post 16650274)

No, actually I'm out of pump at this point. They are pretty much maxed out as it. I have plenty of injector to go higher and now plenty of turbo, but the pumps are the limiter now.

I have no "immediate" plans to rig up a 3rd CP3, but it'll happen....probably a project for next winter. No need for another ECM to control 3 CP3's, it's just further splitting the signal from the ECM 3 ways versus 2 right now.....just a little playing with the Fluke to get that sorted out.

The guys you see running standalone ECM's or piggybacking ECM's are in the older 03-05 trucks. One controls the egine and the other controls all the dash functions.

Originally Posted by cumminalong (Post 16652770)

Combined they can push approx 450L/hr. You can support a little over 3 hp (about 3.2-3.4 hp) per liter of fuel you can move.

450 * 3.2 = 1440 hp
450 * 3.4 = 1530 hp

Like I said, they're maxed out.

Originally Posted by cumminalong (Post 16652882)

1083 hp is on turbo alone, but that is only at 40 - 45 psi of boost on the dyno. The single is so big for the motor and takes so long to come on that it never hits full boost on the rollers. On the track I turn 60 psi. The rest is nitrous.....I spray the living crap out of it.

That picture to the right in my signature is what happens if I forget to turn the timer on for the second stage and it all just hits at once.......tires don't stand a chance. Even delaying the big hit out to around 2.0 - 2.2 seconds it still blows the tires off half the time.

Originally Posted by cumminalong (Post 16653258)

Just look at the compressor maps for those primaries and you can see what they can really support. For every pound per minute of air you can move, you can support approx +/- 9 hp. 1000 hp needs about 110 - 111 lbs/min. Between my two 67.7's......I have about 84-85 lbs each before I really start pushing the map. 170 X 9 is about 1530 hp....that's keeping the compressors in the 70% efficiency island. Plus......I still have 2 bottles in the back. ;-)

I'm used to cranking up the big lathes and pulling .250" off at a whack. Anything less than .030" and it's not even worth setting up the big lathe.

Let's see how bad I can jack up the welds on the aluminum. Aluminum always kicks my butt and I haven't welded it in about 6 months or so.....

http://i288.photobucket.com/albums/l.../image-138.jpg

Not TOO bad. I did have one little bit of burn back I had to touch up, but it's certainly not my worst welds. It'll do for a bit of redneckery....

http://i288.photobucket.com/albums/l.../image-139.jpg

All welded back up and now it has plenty of clearance for the charge piping. There is just about 5.5" between the front of the flange and the oil filter and the radius on the elbow is 4.125"...

That's why I put the forward header slightly lower than the rear header and left a little space between the two of them.

Each of the collectors will have v-band on it. That way I can remove either header separately or the section going into the turbine. It'll be a 3-piece setup, that way if I need to work on or get to stuff I don't have to remove EVERYTHING.

Here's the tricky part.....sectioning the two pipes so that the two 2.75" pipes merge into one 4" pipe.....

The pipes get offset 45*'s to form the 90, then each pipe gets 98*'s worth of the circumference taken out of it and tapered back so each pipe splits evenly and divides the exhaust flow without some big bulky divider. Right from straight pipe and into the turbines without a huge disturbance in flow.

Here's how you set it up.....

Aluminum Piping : atpturbo.com

There are a bunch of places that have them and I usually use the ones from Vibrant, but they only have them up to 3" and I needed a 4" for the compressor inlet. 2", 2.5", 3" and 3.5" are pretty common and occasionally you can find 4" and 5".

I use these for compressor discharges, intercooler inlets/outlets, elbows into the intake plenum, etc.

These cast ones weld pretty well, you just want to pre-heat them a bit when you're welding them to thinner stuff like flanges.

The lips on them are bigger than the specified OD, so they hold boots and clamps well too. I have to grind down the lips to use them with flanges and piping.

Here's what I had going on this afternoon. Started working on the piping off the headers and into the secondary turbine. I had to work on this because the box of bends that showed up didn't have the tight radius bends that I ordered....they sent the larger radius ones that I already have plenty of....so I couldn't finish that one little section on the front header.

First, finished up the flanges on the collectors....

Correct. Everything will get tacked, test fit on the truck, then pulled off and the final TIG welding will be on the bench. I'll be bolting down and fixing as much of it as I can to prevent excess warpage. Stainless like to draw up pretty good when you weld it, so the flanges need to be bolted down to prevent warping and the piping needs to time to cool between welding sections.

Reworked the pipe coming off the rear header today. Wasn't happy with how high it had to stick up to clear the #3 primary so I pulled it off, sectioned it out and used multiple compound curves to keep it fairly low and still clear everything....

Yes, I have a 3rd argon bottle and regulator that I'll setup when I weld the header.

If you don't purge it you actually get a pretty significantly reduced diameter where the slag forms on the inside of the weld. On big stuff (exhaust pipe, etc) it's not that big of a deal. But, when you get .100" (x4) build up of slag inside a 1.55" ID pipe, you cause a significant restriction. You end up with a pipe that flows like a 1.15" ID instead of 1.55" ID.

I think this will be my next piece to work on. Gonna pull that flange of and fit the piping to transition into the turbine. It'll be a lot easier to slighting splay the pipes so welding between them isn't such a PITA.

I decided to gate the pipes directly instead of using the plate. I have plenty of good spots that will flow to the gates better than having to go 90* from the exhaust flow. I'll be able to put each gate right at a bend so it flow straight to the gate, which is how you ideally want it.

I'm seriously thinking about taking the truck for a ride once the headers are done and it's on the truck. Just want to see how well it responds to this setup. I know I have a down pipe that'll fit, just need to whip up a temporary charge pipe.

The outside might look awesome, but inside looks like crap.

Just stuff a rag in the ends and tape the joints. You don't want to do the whole pipe at once, it'll get too hot and distort.

You just run a piece of hose off the regulator, put it INSIDE the rag at the opposite end and start going. Do one weld on one pipe, then move to another pipe and let that one cool....repeat.

Instead of cutting it and rewelding.....little trim off the top...

First, welded the inner portion of the tube together and sanded them flush....

Then bolted the flange to the wastegate plate to keep it from warping. Just waiting on it to cool and I'll weld the inside too. I really should have put the flange on the hot plate for a few minutes. It ain't pretty, but it'll git 'r did.

The bar stock on top of the pipe is just tacked to keep it from warping.
