Agree with those who support the 6L80. Local speed shop owner ran over 550rwhp with a good TCM tune for many miles on a 2010 version in his tahoe. Not until he went to over 600rwhp did anything break and that was a gear in the diff. I would say your hp goal makes it untenable in stock form. But for most - tune and press on.

We’re  going to see what we can push it to. It has a nice torque converter from Circle D and two forms of transmission cooling. Hoping that keeps it together. Looking to push high 700s low 800s. We will see!

I just installed a Circle D 6L80E trans. Most people don't know circle D has a sister company that builds trans. I have the stage 3+ they call it 800rwhp. But many push more in it. They are great people to deal with. But for your build I would look at 6L90E same thing but larger output shaft. Or custom build like Vindicta_Mihi build. He has twin turbo 1000hp. Or if all out is what you are looking for Th400. 

 

I have a multi disc billet stall. and stock block and fuel but have a fuel system ready to go just need to get my new tune set up first for this trans. cooling is the most important want temps under 180*.

Intercooled and BOV is done. The two catch cans are done. Turbo is all snug in its blanket. Just have the 4” exhaust, Armageddon fuel pump and a few snugging up to do and it’s on to tuning. 

 

So so excited for this to come alive. Granite State Dyno and Tune in NH are just killing it.

I wish I could see it when I'm on vacation in NH this summer, but I'll be about an hour away in Madbury. Nice build, it's going to be SO FUN!

I'm super excited. We really have ZERO idea what it will do on the Dyno. Going to start a Pool on TQ and HP. Will start taking bets. :) $5 a square.

Have you ever had a high hp truck before?

 

IMO fast trucks are insane fun, take a car that does 0-60 in 3.5 seconds, and take a truck that does it in the same time, and the truck will be 2x as much fun accelerating.

 

You should be excited.

That’s where I’m at. I can’t wait for the first time a squad of 4-bangers come rolling up and I drop into 15lbs boost and 750+ whp.

 

Or the first super car on the Pike comes screaming up and break loose at 85mph. Let’s goo!

This build is really impressive. I’ve just got to ask what’s taking the shop so long? In May you said the truck had been down 6 months and was almost finished. Now nearly two months later it’s almost ready for tuning :/ I’d not be a happy camper going 8 Kong’s without my truck. Hopefully they are only charging you for the hours worked on it and not by how long it’s sitting there

Yeah No kidding most would!  Honestly I’m fortunate to have more than one vehicle. So when it went down in Jan I took my time finding the best parts then shop. 

 

When I found Granite State Dyno it was just going to be a heads, cam and tune job. Easy in and out. His first availability was around the end of March so they came and towed it.  Then I got to asking questions about prochargers and whipples.

 

GSD had a LT4 charger sitting around so I purchased that and then started accumulating supportive parts. Pistons, rocker trunions, fuel injectors and pumps etc. so that delayed it further.  When they actually went to bolt it up we discovered it was meant for a CTS-V and not a Corvette. Meaning the actual charger about stuck out 1” too far. So I could abandon the build, tune and be done or try something else.   

 

I didn’t want to spend another $6,000 on a Whipple or Procharger or waste the fact I spent a lot of money on upgrades so we decided on a turbo build. In between we’ve had about 4-5 weeks of scheduling events like vacations and weddings etc and since I have other means of transportation I said take your time. And I honestly can’t say enough good things about these guys. True honest professionals.

Awesome build! Cant wait to see it all worked out. Don't forget to get a 2 piece driveshaft if you haven't already, the stock ones don't like it above 100 mph very much.

Where can I get one. Not a lot of info on the net.

I got mine from Performance Driveline out of California. https://www.alldrivelines.com/2014-2018-silverado-2-piece-conversion-drive-shaft-kit-high-horsepower/

 

Easy to install and diff brace came with template to drill into frame. Most local driveshaft shops can make a custom one as well.

      Roll up bed cover experiences

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      New to Me 2010 SLE (Quirks, Issues)

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.

      Yes your absolutely right, I been looking at the 4 inch BDS one and it acutely states you can use the stock 20’s just not the 17’s or 18’s, I also didn’t realize that with my 275/60r20 stock wheels I’m already running 33 inch diameter wheel setup lol so I can just run my stock wheels and tires atleast to start.

      I would expect that to be lift-kit dependent.  If the kit has interference issues w stock wheels, then the kit/manufacturer should indicate that somewhere.
