Supercharging the 6.2L will require you to change the heads to a lower compression unit. The increase in air will require an increase in fuel, hence the bigger injectors. I am old school, and do not believe aluminum engines should be supercharged. Supercharging will also reduce the life of the engine, and of course void any engine warranty. You will also need to beef up the suspension to handle the extra power and torque.

 

My point? DO NOT DO IT, work with what you have, put a high grade aftermarket TC, about 3600, 2.5 str. and a race grade flex plate, that alone will put a smile on your face.

Gurrtz who gave you that info, it is completely wrong. the LS engine will work just fine with a supercharger on it at factory compression and you can still maintain the powertrain warranty, Edlebrock and Callaway both offer warranty to cover the powertrain with their setups.

I have been a long time poster on several LS1 boards, and 10 times out of 10, the people that kept the stock heads (10.5:1), wound up with cracked rings and compression problems. MOST of the people swapped out their stock heads for the lower compression truck heads (9.5:1). ALL THE PEOPLE WHO SUPERCHARGED THEIR STOCK ENGINES HAD TO REPLACE THEM PREMATURELY, due to the strains on the lower end of the engine.

 

Most people had to replace their stock automatic transmissions (4L60E) early due to clutch failure and purchase a beefed up aftermarket unit. People keeping the stock flex plate also ran into "cracking" problems, and bolts prematurely backing out.

 

These are the problems I have read about by people who have supercharged the LS Gen III engines.

I have attended car club meets where the engine would not turn over, and in cases where "Hi Torque" starters were not installed, "cracking of the starter flange" due to excessive torque twisting of the starter occurred.

 

ANYTHING OVER 5lbs. BOOST, AND IT BECOMES A CRAP SHOOT.

 

I do not understand how the FACTORY warranty stays in affect when you are modifying the engine block, plus altering the stock tuning.

 

I DO understand that the aftermarket companies have a warrenty implied, however do you have to have it professionally installed?

I don't think that's a fair comparison. You can't blame the supercharger. I'm sure with the way 90% of people who ran superchargers romped their trucks they would break stuff, with or without one.

In regards to supercharging the trucks with the 6.2 that has the 10.5:1 comp.

I'm sure GM spent more money then anyone could imagine on R and D before choosing the right S/C to put in there truck along with everything else that goes along with the mod to keep it all together and still offer a factory warranty. Besides I don't think Callaway wants there name dragged threw the mud if they screw up on the factory truck mod and motors start blowing up.

I'm positive that those individuals that have had problem with the high compression heads used to larger of a S/C and may have also cut corners to keep the cost down.

The FACTORY warranty remains in effect, with a three year 36,000 mile warranty from Callaway on all Callaway installed parts. They also offer a 100,000 mile warranty for their parts as well. GM also has superchargers on the ZL1, the CTSV and the ZR1.

I don't know anything about a modified block.?. Warranty available online at CallawayCars.com

I need some clarification here, are we talking about purchasing a GM vehicle WITH a supercharger installed at the factory or authorized dealer (i.e. SLP), OR are we talking about purchasing a GM N/A vehicle, THEN adding a aftermarket supercharger? If it is the for mentioned scenario, there should be a factory warranty applied, if it is the last scenario, you are on your own with no factory warranty, and the warranty implied by the supercharger company is only on their product. You would have people installing superchargers, changing to a smaller pulley (i.e. higher boost), not having their engines dyno tuned properly "blowing s*%t up". I do not see how a aftermarket supercharger company can warranty the entire engine on your vehicle on a private party install. Someone please help me understand this.

For warranty with aftermarket superchargers, has to be installed by an ASE certified Master Tech, you must use their tuner, and can't change pulleys

I put an Edelbrock E-Force supercharger on my 2011 Gen-lV 6.2L and i'm running 10.5 psi of boost and after roughly 7000 miles now,things are all good. I think it as to do with the tune, can't have any detonation.I'm not worried about any motor waranty,i take full responsiblity for any thing that breaks.My truck is paid for and happenes to be my hobby.If it was mt only means of transportation and i was still making payments,i might not have put on the headers and changed the pulls.But damn,this truck is fun to drive and my new injector came today,so it's time to bump it up a little more. I may stop when i get over 500 whp ,at 422 right now.

gurrzt is making a valid point. GM isn't going to warranty damage caused by an aftermarket add-on. If the SC manufacturer provides a full powertrain warranty, then that's something that the owner gets to work out with them. GM definitely won't warranty it. Toyota offers a TRD supercharger (I think it's made by magnacharger, but definitely not Toyota), and if installed by a Toyota dealer, does not void the powertrain warranty. Even so, I've read a few posts where folks were given the run around, or denied service. I can't verify that, but if I read it on the net, it must be sort-of true... :sleep:

The supercharger company (Edlebrock and Callaway) warranty your drivetrain for 3yr/36,000 with their setups as long as installed by a certified shop and as said as long as you use their tune, this is on a vehicle that did not come with a supercharger from the factory.

 

Once again I know several people that are running superchargers on vehicles that did not come with one. I have a 2008 C6 Vette as well, there are several people in the Corvette club with 6.2's that are now running the Edlebrock E-force kits with no issues.

Question number 1.

Still covered by factory GM 5 year 100,000 mile warranty. Keep in mind that you can Order option B2K on a GM Corvette order form and your new vette is shipped directly from GM to Callaway for the factory authorized modifications. Look up the 25 year history of Callaway's relationship with GM, Chevrolet and Corvette. A history that includes being one of the few companies to ever get a Regular Production Option from Chevrolet. There is also a history of racing, and winning.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
