I am contemplating putting a EB supercharger on my 2018 6.2L GMC Sierra. Wanted to see if anyone had done this before? Was it worth the investment? Any issues? Thanks in advance.

Not sure of anybody on here going with an Edelbrock kit but there are a few that have done whipples which is the same style blower as the Eaton the EB kit uses.

Any bad things to say about them? Anything I should be cautious of? Does the transmission hold up to the increase in tq and hp?

 Answer to the tranny? NO. It could be fine if you're just loafing around most of the time, but if you actually use the power or drive the truck hard & work it like a truck, the tranny most likely won't hack it. Hell, the tranny/TC can barely handle the STOCK output of these trucks. The 8 speed was a "band-aid" by GM they knew/KNOW is flawed & was a temporary solution to "keep up w/ the jones's" until their joing-venture 10 speed developed w/ Ford could be implemented.

 

Whatever you do - yank ALL the AFM related hardware while you're at it going w/ a new cam/lifters & I'd also swap out the torque converter for a beefier/more well designed aftermarket. With a good tune & fresh fluid the tranny would have a better chance & not grenading itself w/ the AFM delete & TC upgrade. 

 

I would probably consider upgrading the driveshaft too if you're adding that much more HP - again, stock driveshafts have issue dealing w/ STOCK power levels - btw, you could punch a hole through your driveshaft w/ a screwdriver......you don't want it tearing apart on ya @ hwy speeds.

 

I no longer have a GM truck, but I do have a C5Z vette, alot of guys go w/ centrifugal style superchargers for peak HP + packaging, but if you notice all factory boosted GM engines go w/ roots type blowers....while may not make the same power, consensus is they're more reliable & truly drive like stock - Edelbrock's SC's are roots type bolt right on top.

 

I'm curious - has anyone succesfully transplanted the blower from an LSA or LT4 to a GM ecotec engine? Is it possible? I saw a G8 GT @ a car show last summer that had the blower from a wrecked CTS-V (LSA) - THAT would be an interesting build.....and may very well be cheaper/easier?

Lastly - I know you didn't mean it that way, but I had to chuckle @ "investment" - its a TERRIBLE investment, but it'll put a smile on your face & YOLO

 

Keep in mind - both Ford & RAM will be coming out w/ factory blown warrantied 700+HP trucks in the next year or so......

I have a Whipple 2.9 Liter Twin Screw supercharger on  my truck. No issues with mine. I drive it 100 miles a day and love it. I had a shop put it on for me. Any reasons wanting to go with EdelBrock? Whipple and Magnuson are the most popular for our trucks.

I was looking into whipple as well. The guy I spoke with recommended EB bc he said it gets you more HP and TQ for about the same cost and they had one of the best intercoolers for the price.

Fair enough. I don't know much about the EdelBrock ones but they've been in business a long time and sure they make a quality product.  Hopefully someone else will chime in who has direct knowledge of that brand installed. Good luck to you. Looking forward to seeing it done.

Whipple makes the most power hands down.  Edelbrock uses Eaton rotors and costs more money than the Maggie and SLP Eaton designs, that's why not many people use them .

      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.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.
