Are you Launching in Auto and switching to 2wd on the fly?

Yes, you can feel the difference almost instantly when you turn the dial back to 2wd. I did it a little late on that run, usually try to do it at the top of first.

 

It just releases the clutch to the front, not harmful to the system.

After all that about intakes, I thought for sure you'd have one. Lol.  Video seemed loud in cabin for stock intake and exhaust. Nice run.

I’m a former addict. Spent every nickle on car mods in my early 20’s. Built motors, turbos, trans, suspension, everything, left me broke with incredibly unreliable cars. I’m super cheap now.

 

will probably add bilsteins and then an intake though eventually

Interesting, I have been wary of doing this because I don't want to break anything.  As the 6.2 owners out there know, anything over 1/2 throttle off the line will blow the tires off, and trying to roll on usually has the transmission shifting into 2nd before you can get the pedal down..

Theres guys that run 11’s that launch like that. Our drivetrains are beefy.

Blackbear dyno tested several intakes, specifically on the 6.2. Airaid jr actually didn’t make any more power than stock. Full airaid made a lot of power, not sure if you can just buy the box.

I've done the 4wd launch before in my truck, right at 5.0 flat for 0-60 is where it is at. Wifes little Audi SQ5 with 450hp is neck and neck at the 0-60 but then walks away from my truck. Must be the 43xxlbs versus the trucks 55xxlbs. My toy car is 37xxlbs and has 455rwhp, the best I have got the 0-60 on it is 4.0 flat.

Yeah I’m really happy with the truck’s acceleration. I had no idea it was going to be that quick when I bought it. Numbers are one thing, driving it is another.

 

No it’s not fast after 60, but I mean in real

world street driving 0-60 is king. The truck feels like a complete animal from a traffic light. You’d need a seriously fast car to keep up in race from a stoplight. Most fast rwd cars have trouble hooking on the road.

 

I also have a coyote mustang. If I had to bet money on a stoplight race for like 500ft on a public road, I’d grab the truck.

 

disclaimer- i dont stoplight race a lot lol, just using it as an example to describe the on-street performance.

I used to routinely destroy 11-12 second Fox bodied mustangs on the street with my non-intercooled, 13-second Grand National way back when.  Not even the fastest exotics could keep up with my '86 Grand National that would run 0-60 in 3.9 seconds on the dirtiest road from idle and 3.7 with a light power brake launch.  Traction was and is the key and of course a better reaction time!

 

Another word about BlackBear.  My truck now makes 302 rear wheel horsepower and all I had done was a mild tune by Justin of BlackBear.  Justin would tune it and I'd ask him to tone it down.  Still the truck just keeps running better and better.  The horsepower was calculated by using the forumula to calculate effective RWHP through the traps at the end of a 1/4 mile run.  Factory flywheel rating is 310 hp.  Not sure how much is lost through the transmission, transfer case and differential.  I seem to remember that the old 200R4 took 28 horsepower and the Turbo 400 was in the 40s.

 

Anyhow, these Gen V motors are even more impressive power wise, enjoy them fellas!

What size tires are you running? I can brake boost mine in 2wd with TC off and it will chirp them all the way through 1st but wont outright break loose. I have 33x12.5's though so it is a lot of rubber on the road. You seem to be in the 5 seconds flat range. My time only works out to about 6.5-7 sec with some spin so I will have to try 4x4 when the winter sand is off the road and my truck is out of hibernation. My only mods are the huge boots that are about 15lbs heavier per corner and an AFE intake.

      I wonder how much carbon is on all those high mileage valves?

      AFM Experience

      By Atlas · Posted

      When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007

      Bridgestone vs Goodyear tires?

      By Chuck FB · Posted

      I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.
