Armageddon actually didn't supply a map sensor at all, so I still had the stock 1 bar sensor. I could have definitely got by with a 2 bar sensor as they will read up to almost 15 psi of boost, which is way more than I'll be running, but summit Racing had the gm 3 bar sensor in stock and they have a physical location close to me and I just picked it up.

 

Yeah, the higher the bar number the higher the pressure sensing ability of the sensor, and they read in absolute pressure which starts from a total vacuum. Standard ambient pressure at sea level is 1 bar or about 14.7 psi. So essentially a 1 bar sensor will only read a vacuum, a 2 bar sensor is good for just under 15 psi, and a 3 bar sensor is good for about 29 psi.

 

As a bonus, when I end up building a forged engine at some point, I'd like to turn the boost way up and make some really big power, and I can just keep this map sensor. That's a long ways down the road though

Hey man, great looking truck. I've seen some of your posts here and there and I've always admired your wheels and stance, I'm thankful that you created a build thread so I can easily find your specs lol.  I'm really looking forward to the results of your turbo setup. Which turbos did you go with?

 

Prior to my Silverado, I had a STI and I was making 550hp to the wheels on the gen 1 gtx3076 (on e85...once you use corn, you'll never want to use gasoline again). I was planning an upgrade to the gen 2 gtx3576 but I ended up selling the car. I am very new to the gm truck scene as I bought mine (2016 crew cab) in February.

Thanks, I appreciate it! If you have any questions, feel free to give me a shout and I'll answer anything I can.

I went with the GTX3582R gen 2 turbos. Way too much turbo for my stock 5.3, but I'm planning on a pretty stout 400+ cube engine at some point so I went big so I can grow into the turbos. I can't wait to get the truck tuned and to the track to see how she does.

Wtf lol, those turbos are wayy too big. Twin 66mm! Pretty sure they are good for like 800hp each.

 

They are too big for a 1000 truck lol.

 

Unless you’re planning on dropping $60k in mods on a 1500hp truck with an entirely new drivetrain, I would definitely try selling them and go with something smaller. You’re missing out on atleast 1000rpm of boost.

The goal is 1200ish at some point, so I went big on purpose. I honestly expected them to be laggy, but even without a good tune they're not bad at all.

Good news, just got back from the tuner. Truck put down 512 hp and 534 ft/lbs on 7lbs with E85 and a pretty conservative tune.

There is definitely more on the table, but without a boost controller, I'm limited to whatever springs I put in the wastegates. But we all know this isn't the end of the road.

Nice!! How does the truck run? Get on it yet?

Oh you know I did! Low throttle, it drives exactly like a stock truck, putts around nice and laid back. If I step on it in 2wd, instant smoke show lol. In 4wd however, even on a boosted launch, there is no spin at all, she just launches and pulls hard. So much fun!

We just did driveability tuning on 93, no power pulls. The idea is for the truck to live on e85 or better, but still be able to run 93 if i get in a bind on a trip or something and can't get ethanol.

Made 2 runs at the track over the weekend. Ran a 12.88 and a 12.91. Not too shabby for a stock 5.3 on boost.

Already need more lol. Aem wideband and GFB boost controller have already been ordered. f57e0509eecb958ca1c355f0555c7115.jpg

    • I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc
    • Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-
    • Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.     
    • I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
    • I do too. I’ll never be stuck again 😂
