Trying to have some restraint ... but

Thanks for the kind words. I plan to stick to the installations and detail oriented dives into the DIY experience vs the entertainment factor which will hurt the channels traffic. I'm ok with that.

Glad you enjoyed it!

Thanks for tuning in and enjoying the content

Coming soon! I have to help sort some CA gas and 2021 emissions tweaks and I will be on the dyno and in the dirt.

Thank you. I just try to do my best every time. The last thing I want to do is cause a failure in the field due to something that could have been avoided. Check and double check.

It's an impressive package and more video on the dyno and real world use on and off road

Thanks! Who knows a Silverado might be in my future. Supercharged 6.2 LT motors are much more fun ;)

I’m currently talking with Chuck Mallet about purchasing one of these for my 2019 ZR2. Sure wish he’d offer a little better pricing. I have a 2018 denalli 1500 with the 6.2 that ate the cam so I replaced it with a txsp stage 1 cam and with headers, tune and e60 it makes 485rwhp. Awfully tempting to throw a blower on that and go raptor r hunting😅

Thanks for tuning in

I appreciate the feedback

Yeah loosing you cool in the midst of a detail oriented task doesn't serve anyone well. Its time to just get through it as efficiently as possible. IF it wasn't and issue of breaking in parts i would have stood on it. She runs pretty awesome today and no regrets.

Enjoy the exhaust, we put a lot of time into making something different.

I feel most 3.6L owners would agree. Get boosted @mallettcars

Its a lot of steps but its not overly technical. take your time and bring a 6er

Thank you

Yes .. .we got the blowers near the same time. We are pretty chatty. Thanks for tuning in, subscribe and stay tuned for dyno, dirt and street testing.

I'm looking forward to it! Thanks again for the awesome videos!

It is very addicting but that's what hobbies are all about. I second the supercharger upgrade lol

The S&B air box was used only for testing naturally aspirated and with the supercharger, I am running the stock air box again but modified. I opened up for the stage II pulley and to be able to use the snorkel.

So far a modified Stock Intake box is the best solution but I am looking into modifying something else to work.

It has never come off since I have installed it. I ran for a week or so without a rear spare tire when I swapped to 35s but the Ultraswing has been a part of the program since its initial installation.

@@exhaustinglife Cool. Are you experiencing any rear suspension bounce on your ZR2 since installing the swing? I am experiencing a fairly pronounced suspension bounce on my ‘21 ZR2 after installing the same swing. Everything is torqued down and tight. Neither the swing nor the tire are bouncing or wobbling, just the rear suspension is not reacting well to the new weight distribution of the truck. I’ve tried everything from varying tire pressure, adding and redistributing weight but nothing has eliminated the bounce. The dealer thinks that because the swing pushed more weight beyond the rear axle, that changed both the center of mass and the intended performance of the tuned rear suspension. After removing the swing, the truck drives perfectly. Any ideas??

@@r.p.8402 I had already modified the rear suspension and aftermarket shocks plus add a leaf both helped manage the extra load. You are right regarding the increased mass and location which will both effect stock suspension dynamics but just like adding other "gear" the tune of the suspension will be effected.

It is but its not a prominent sound .. you have to be listening for it ... unfortunately :P

They do offer profession in house installation and tuning. Just reach out to Chuck Mallett when you call and let him know when you need to schedule an installation or what needs to be calibrated for when dialing in your rig.

@@exhaustinglife Thanks man!

Did you ever go down the boost path with your Blazer?

LOL sorry its a problem ... really, an addiction. I could be smart and takes some risk on cryptocurrency or be 100% satisfied by the sound of a blower and spinning tires

The fact i had to remove the valve cover was only a part of this install because i discovered a factory seal that was leaking. Normally that is not a necessity and the installation should be a weekend job for a mechanically inclined DIYer. The most difficult part of the install was the actual physical aligning and mounting the housing to the lower manifold. Its heavy for a one man job ( 2 people would negate this issue) Power gains vary from 100-120 wheel HP depending on stage 1 or 2 and observed mpg increase has been about 2.5 - 3.0 on stock gearing 33" tires and about 500-600 lbs of daily payload

I do have some follow-up comments I have been waiting to edit, but I did end up selling the truck for a new platform last year, so my focus has been on the most recent adventures. I do owe you guys a recap of thoughts and commentary.

@@exhaustinglife Haha I ended up buying the kit for my '22 AT4. They just came out with a transmission tune for it as well. It's *awesome*. Your video was one of the ones that convinced me to get it!

I am a fan of the 4.10 gear set with the 8 speed and 35s. That will be the direction I am going. It will recover some economy and provide enough mechanical advantage to negate the load of the beadlock wheels and heavy 35 inch tires. I have been in a few 4.56 geared trucks without a supercharger but with 33s and 35s and one with the Edelbrock supercharger and 35s and to me, it didn't feel like it mated well to the 8 speed gear box and adaptive programing on in the truck. The lower gears felt too short and not very usable especially in 4 low.

The supercharger install was after but in order to remain CA (50 state) legal I had to retain the factory air box. It could be made to work but could not pass visual inspection here.

Still running strong. It has been 12k since the install and the the only thing I would like to dial in the tune a little more when HP tuners releases the full flash update. I cant imagine 440 WHP is possible or accurate as that is over 200 whp over stock. The stock crank HP is rated at 308 and the stock whp of my truck was 240 ish. The Stage 2 package will add 120-130 whp but that gets you to 370 at the wheels. My numbers are on a DynoJet AWD eddy current dyno so they emulate more real world numbers not the inflated inertia dyno stuff people like to talk about. I also tested on 33" and 35" tires

1. It's a 2 day job working 8 hours a day with hand tools in the garage. You might be able to cut it to 12 hours if you wanted to push it but with as many steps rushing is certainly not the goal. 2 / 3. I love the additional power and even though there are some quirks with 2021 tuning its nothing that takes away from the system and these are unique issues to the CA 50 state vehicle and will resolve with a little time and some logging and updating but would not keep me from saying this is a plug and play set-up ready for sale. 4. They offer a 3yr / 36,000 warranty given certain conditions are met. Having installed, tuned and operated a dozen or so Magnuson supercharged vehicles I am not worried about the OE engine/trans warranty component as a simple N/A vehicle running a tune / calibration or a bolt on Throttle Body effectively negates the warranty as well. That being said, if both the tune or a bolt-on engine part can void the powertrain why deal with those kinds of products at the lower end of power potential and drivability at the same cost to the warranty? (and don't forget Mallett offers their own limited warranty) Im still a very happy owner and looking to dial in the tune for my specific needs once the HPTuners software allows the changes I want to make.

1. Covered it in another comment but its a 2 day garage job. 12 hours if you push it. 2. The best part of it is that the truck drives and behaves like stock but with more power. 3. I never got around to altering the tune as the software was never made available from HPTuners. Typically I like to dial in the tune for the conditions that I operate the vehicle in. I have tuned a little over 100 GM vehicles in my day (used to dyno tune friends vehicles and eventually customers.) 4. Any modification will be a consideration by the dealership to either comply or void a warranty. Legalese is not my specialty and the conditions which each dealership operates varies drastically but we do have the Magnuson-Moss act for some protection.

Waiting to get some time on the dyno. Hoping I can get on before the end of the month.

Roughly with the 35s and stock gears, I saw about 2 mpg restored. Keep in mind my truck was fully geared up all the time, rolling around with about 6,000 lbs and getting back 2 mpg was a huge impact at the 12 to 14 mpg mark. As much as that was notable I would have done it without the mpg benefit as the truck's drivability was not only restored but enhanced.

Thank you for your response, I’m considering adding a power adder to my 2022 Canyon AT4. (If we buy a smaller travel trailer). Your video on the mallet super charger is very informative. Thanks for your input.

So far so good. Still waiting on an unlock for the TCM to get this set-up where I want, but I could not be happier with the power delivery at WOT and the additional power to help with the heavy and tall wheel and tire combo with the beadlock 35s. I have had no issues driving around town or any concerns with the 1000's of miles of dirt in remote areas I have covered. The S&B was not CA CARB legal so I could not keep it on the truck. I got it from a private party and was curious as to the sound and power gains so I did the flow bench and dyno work out of curiosity. Also with the plans of the supercharger coming in, it would require extensive modification and also would negate the fact I acquired a $7k CARB legal supercharger to avoid any emissions related issues. Outside of CA and without the supercharger, I would have it on the truck.

I filmed a 1 year review and just need to get it through editing. Been busy this winter.

The stock SAE crank horsepower is 308 but at the wheels on my AWD dyno it made 231 WHP (on 33" tires) The supercharger was good for 103 HP at the wheels for a net of 334 WHP. If you keep in mind the parasitics of the baseline to rated power (about 25% loss) it equates to about 445 at the crank but that's just mathematic speculation. I am using the supplied Tune Mallett provides

How can I help?!?

if you have ever cracked open any of the fluid systems of a motor and then started it's a pretty common thing ... but can be disconcerting for someone who has never done it before.

@@exhaustinglife I'm just saying I can't smell through youtube.

@@nsk8ter524 I get that, but I was speaking to the person who might be doing this at home and the experience they might have not so much the new "smell-o-tube" app for YT :P

As an avid DIYer I don't worry too much about warranties. I typically am way ahead on preventative maintenance and regularly inspect the vehicle for wear related issues as well as am fairly cognizant of abnormal feedback from the vehicle while driving. As you saw in this video, I found a factory defect in the motor in the process of making a modification, which is not uncommon in my experience. In cases of factory defects at a recall or TSB level, warranties are not typically an issue. Now technically, modification will void warranty coverage related to the system you modified or can be considered void only in the instance direct causation can be proven. In my experience, I have found that being level-headed and speaking the language (ASE certified mechanic) helps in working with a dealership. Having a relationship with a dealership and finding the right one is also a variable that can affect your warranty process. I have had a lemon law motor issue with a Cadillac and even warranty shock and spring issues with the ZR2 both with many modifications all taken care of under warranties.

I'll provide some updates as time goes on. I have about 10k miles on it and no issues with powertrain. I don't really abuse the power and am mindful of what having an addition 130 lb-ft of torque changes in driving. It's honestly more a challenge integrating with the PCM / TCM programming than with the mechanicals of the transmission. This has some drivability compromises in smoothness in shifting but nothing outside of my experience with supercharging on other GM platforms.

... for those going through the process not the viewers lol

It's not for everyone's budget but there is no other legal way to roam the streets with this kind of power in a 2021 Colorado

No issues during the time I had it. If you watch the end it shifted firm but not too aggressive or else it would enact torque management protocols. The 8 speed seemed to be fine but I know getting the exact tire revolutions was imperative. Any changes with Axle Gear Ratio and Tire Size can effect the shifting.

How much time and driving did you have to do for your ZR2 to go thru the learning

@@ThomasYore I can't exactly say when the adaptive driving was "done" sampling but it was driven about 100 miles a day in traffic and highway so it got a lot of use fast. I never experienced and adverse behavior shifting but you also need to consider this was installed in a truck with only 18,000 miles

Unfortunately no. The engine is similar but it not the same. The supercharger kit is dependent on the configuration of the engine and specifics of the actual vehicle. The transverse mount and the TB position alone would prevent the Mallet blower housing and pully system from being used without extensive modification. I think that back in 2019 Lingenfelter had suggested that they would try to package their smaller housing 1750 supercharger in the Blazer but I don't think they ever got around to it.

Yes, long term i have watched the mpg up 1.9 since the supercharger install on the lifetime MPG screen.

@@exhaustinglife excellent info and seems to coincide with the manufacturer claims. Thank you!

91 for California or higher only. Cannot run mid grade pump gas.

I go through vehicles about every 2 or 3 years, and as you can see on the channel, I now have a Jeep Wrangler. The Bison is still running strong in its new owners' hands and just keeps cashing in on the Smiles / Gallon. It was a hard trick to let go of because it was a strong runner, but my thing has always been about the build, not so much about long-term ownership. I mean, how much more was left to do? Boost is king when it comes to power. Mallet is still the hands down go to supercharger for the best power and most consistent performance. If I had to do it again, having driven 2 other Magnuson based kits, it would still be flying the Mallet flag.

@@exhaustinglife Thank you i'll look into it

Unfortunately entirely different pcm / tcm amongst other physical characteristics that would prevent bolting on

@@exhaustinglife I can fabricate a bit, is it at all possible?😢

@@jdmtechllc6589 The fabrication portion is not the biggest obstacle, it going to be how to tune the calibration. As far as I know there is not a tool available... yet

@@exhaustinglife Okay I will look into the ECM type do some serious digging and report back, I actually have my own channel going too, I appreciate the video and the advice.

I have no idea. Unless the air box had the same exact inlet and outlet position as the stock plastic box, the kit they provided is meant for a stock airbox. Some modifications may be possible but whether the changes would effect the installation or tune would be pure speculation.

Any modification that replaces a OE part with an aftermarket part may void the warranty as perinate to the system or part that is being replaced but dies not affect other warranties not related to the modification. For example the supercharger modification should not effect the warranty as pertinent to the stereo system or paint and body finish. As far as the Mallett Supercharger there is a 3 year / 36,000 Limited Drivetrain Warranty offered if you meet the terms of their warranty contract as noted here: mallettcars.com/wp-content/uploads/2019/05/MALLETT-PERFORMANCE-CARS-LLC-LIMITED-POWERTRAIN-WARRANTY-STANDARD-20181017.pdf

@@exhaustinglife That is very, very informative. Thanks for the pdf. Do you have ASE certification?. I love my ZR2 and want to keep it for a long time. So please excuse any stupid questions. I have....

@@joaquinmojado Some time ago in the 90's and what feels like a different lifetime, I got my ASE A1/A6/A8 and L1 working at Pep Boys. Ask away, if I can't answer someone usually chimes in who knows more.

So far reliability has been a non issue with driveline or powertrain with over 25,000 of use rock crawling, high speed desert and trail use. Maintenance is key in my mind. Bump up intervals and inspections and remember that saying, "when you play stupid games you win stupid prizes." Overrevving the truck, not managing power application, exposing the driveline or powertrain to sudden changes in load or not being an observant driver/owner can be just as impactful to the reliability of event he stock truck. As far as wear and tear, it will accelerate wear but nothing outside reasonable use. Running 40" tires and using stock axles can be survivable but it doesn't mean any change wont impact stress or wear. It's a trade off of most any performance product out there, stiffen a chassis and you move the failure point, increase the power and you are going to consumer more tire. So far Mallet has done their homework and made a reasonably good modification that keeps the fun factor in ownership alive with the truck too.

@@exhaustinglife thanks for the detailed response.

Hard to say until you let me know what "as good" means to you. Without actually having the Colorado/Canyon version available to drive, I can only go by my impressions on F/S Silverado 2.7L with similar powertrain. Will the Turbo 2.7L make more power? No. Will the Turbo 2.7L have as much available torque off the line? No. Will the Turbo 2.7L deliver power as quickly? No. With all of that said does the 2.7L pack enough punch for what it is? Possibly yes. Keep in mind with any aftermarket power adder performance upgrade, the integration into an OEM system is absolutely critical to make the ownership experience good. The Mallet supercharger system has so many of the small details considered for proper packaging, reliable performance and great power delivery which in my opinion makes it the premier choice for aftermarket power while still having 50 state emissions compliance. With all that said there is also a consideration on parts life cycles. Stock power levels will provide the longest most trouble free experience and quite a bit of room for errors in driving, maintenance and performance. Think of it in the context of race cars vs stock cars... the closer you approach race levels, the more consideration you have to make for every other system. Driving faster means demanding more from every component on the vehicle, suspension, brakes, chassis, transmission, rear end, etc. The preventative maintenance, routine maintenance and inspection intervals all have to increase to make sure catastrophic failures are not looming near as you exceed the nominal use of each of the other systems in the vehicle. Race is fun but you cant have the expectation that compromises are not traded for the race experience.

@@getrichqwik Your analysis is accurate. Did you know, the 2023 2.7L ZR2 (Comes with High Output as Modified from WT or LT Models) will produce more HP "310" and Torque "430 Ft. LB" than the V6 in the 2022. Reason I ask is because of concern over the direct port fuel injection that tends to create carbon build up on valves. Meaning potential decreased performance in the Long Term.

@@renevelez9444 The 2015-2023 3.6L V6 is also a GDI motor and has the same potential issues with carbon build up as the new motor will. I used some newer products from Lucas Oil for GDI motors specifically to address top end cleaning as well as a newly developed oil stabilizer for the lighter weight oils for economy and multi-displacement valvetrains.

To some degree yes, but the packaging is truck exclusive meaning the emissions / electrical / cooling lines will all require massive customization in a transverse application. It would also negate any legality in a different platform. Just to put things into perspective this kit is not even a bolt on for the Camaro 3.6L or ATS / CTS platforms that are standard fitment. Probably looking at a 10k+ investment with fabrication and still not being legal or having a tune.

@@exhaustinglife thanks for the reply. Do you know of any supercharges that might work well with a traverse? Edelbrock?

@@tactical_mortician Same problem with any of the supercharger "kits." The supercharger head unit itself is not so much the issue as much as the "kit" is what makes it work. In any instance its a matter of how much fabrication capability you have and/or how much more you are willing to spend to make it work mechanically. After that software is necessary to make it run and unless there is a recalibration software company that makes something for that chassis, it complicates any kind of major mechanical engine modification.

I have not looked into the Superchargers for the Gen I Colorados but this kit is not compatible. This kit is designed for the v6 3.6L and all the packaging would make it near impossible to fit.

No Brembo braking on this build but I do like their parts. I did put Brembos on an older project Mustang I had. Big Brakes should be a consideration for any big power build

I sold the truck for the Jeep almost a year ago. I didn't have any issues at that time and don't suspect that it should have anything either.

@@exhaustinglife i see you bored quick haha

Air To Coolant reservoir is under the stock coolant tank by the passenger side firewall

@@exhaustinglife thanks

Its an installation video with some preliminary comments on the process.

There are a few physical restrictions to consider but mostly I would want to test one and see how it effects the tune. Changing the position of the MAF or the MAF tube diameter will effect how the tune in the supercharger responds.

@@exhaustinglife ty for the reply

Stage I + Stage II Pully and tune is just under $7800 + Installation

The majority of the CAI systems pick up gains in eliminating the baffles and indirect air pathway of the stock engine cover / intake tube assembly. The supercharger itself removes all of that and the air box lid is not particularly an issue and additionally allows for the stock mass airflow sensor to remain unaltered. A higher flowing drop in filter seems to give the same effect as a cone style aftermarket without requiring a huge plenum to allow air around the element of a larger cone style filter. Packing is tight already due to the water tank needed to be nestled behind the factory box. In consideration that the system tries very hard to have a stock appearance (albeit a supercharger planted un the valley) I am not particularly put off by the stock appearance. Would another part add to the cool factor? Sure. Would another part increase performance? Its possible. Would another part increase the price? For sure. Would another part, sourcing and manufacturing effect the ability of the system to be delivered in a timely fashion? Absolutely. The packaging of the Mallett is unique as compared to the other offerings and by nature will have some additional costs with its unique and proven design. It's not the right choice for everyone, in turn not the highest volume seller to take advantage of volume discounting of parts but it does have its own performance benchmark above the others and was never designed to the the cheap solution.

@@exhaustinglife somebody spending over $7,000 on their engine doesn't care about having a stock appearance. And I've seen other superchargers like the Edelbrock that is half the price with very similar performance output. For around the same price you could have gotten a custom twin turbo setup and gained even more power

@@headkase11 I do care how it looks and it is worth the money to me which doesn't mean you need to care how it looks or should judge what people find valuable. The Edlebrock makes 30-40 less HP to the wheels (than the stage 2 Mallet) and will not maintain the IATs over repeated full throttle passes netting losses on back to back throttle pulls. You also realize not one of the other supercharger manufacturers changes that air box either. Not Lingenfelter, Not Callaway, Not Edelbrock ... the only one that did is RIPP as a result of the centrifugal design and guess what? They don't make them anymore. I have driven an Edelbrock setup and its a good kick in the pants but even with 4.56 gears to my stock gears (3.42,) it could not pull away past my driver door and by 3rd gear on repeated pulls, I was over truck length ahead. They are not comparable in output moreover the Edelbrock was not CA legal for my 21 when I had acquired mine (i think since March of 21 the EO was finally released.) And yes emissions compliance is worth it to me also so the twin turbo is out. But hey, if you are budget minded the Edelbrock is a good choice but If you want more then you will pay for it. Edelbrock is a reputable brand using the same internal design but a smaller supercharger (1.7 to 1.9) with less intercooling and tuned for lower rear wheel output. They are just different.

@@exhaustinglife I'm sorry if I was coming off like a dick or being hard on you. You're set up is extremely awesome 🙌🏽🔥 and I really appreciate your break down of this supercharged system. And I just check and thought the other systems were a lot less than I thought but they are $1-3k cheaper including install. And to make up for the 30-40 less horsepower I you could use that extra money for higher flow exhaust and suspension upgrades. I'm sorry the deal hunter inside of me takes over brain lol I'm not a cheapskate but I tend to overanalyze things and then attack the internet to find the best deal for the performance or value. One very important question! Does this kit include a ECU mod or what ever it takes to turn off the speed limiter? We can't even do a full out quarter mile drag race because it's limited to 98mph 😭😭😭

@@headkase11 intake and exhaust will require a recalibration on a supercharger tune and will not be as simple as you might expect... ultimately those can be added to any system and the lesser expensive will still come up short in the long run. The ECU is not a canned tune as such you can do what ever you like including running without a speed governor, i don't have one and i have adjusted for 33s as well as the 35s as needed.

Intakes don't make "boost" and I already have a supercharger ... so there's that.

It's a truck built during COVID. QC was always my concern with union strikes and furloughs but it became a reality. It was not a huge set-back and I'm not going to let that take away from the otherwise great time I am having with the truck. GM made a bad a$$ machine with the ZR2

Yeah love the truck but dont like the other minor problems like soft thudding sound coming from underneath. I felt like my 2020 was built during covid after lunch time.

@@MitsuFQ400 what's the sound? Im thinking about building a "YT Shorts " series on all the noises of the colorados and canyons :D

@@exhaustinglife the first part of our driveway is rough so everytime i go over it i hear a togtogtogtog sound. According to other channel (Fondupots Garage) its coming from the leafs so im considering buying his fix.

@@MitsuFQ400 I will add this to my list. So far I have 5 noises to look for :)

It's perfectly fine to drive a stock vehicle with stock power levels, and the vast majority of owners will. The truck is very capable and it's why I reserved this modification for last. Getting street legal power is expensive and not for the faint of heart. To put things into perspective ALL engine tuning is illegal that is currently available to this platform and most produce under 15 hp at the wheels. Exhausts and intakes will contribute the same power but can do so legally at 2 to 3 times the cost of a tune or calibration. V8 motor swaps are out of the question if a bolt on supercharger is not in budget as they can easily crest $10k plus just for the parts. Mechanically speaking, the challenges are high for true integration (with the 4wd system transmussion and other body controls) are costly and above most consumers' ability levels. Keep in mind that nothing ihome built in the motor swap world is 50 state road legal without an emissions referee's guidance. For what you get with the supercharger package, it turns out to be a pretty good value if you look at the alternatives available.... or you could just move to a 2024. 6.2L Silverado ZR2 Bison (470 Hp) for $80k. 2024 2.7L Colorado ZR2 Bison (430 Hp) is about $60k (my 2021 Colorado ZR2 Bison (450 Hp) was $51k plus supercharger)
