True…..yet I had heard from a few GM guys before this past “election” that depending on who got in the supercharged truck were on the table. The pandemic hasn’t helped especially with chip shortage on all the other “bull$h!t that has gone on. I truly believe they are waiting for this to

settle all down and 2024 they will bring them out. They have nothing to lose and everything to gain. No auto maker makes a full lineup of supercharged SUVs and trucks. Yes Ram makes 1 truck, Ford has  the Shelby, but no one has a full lineup. It’s there for The taking if GM would just pull the trigger. 

 

the EV power is great but WE as a society are years away from actually using them as just more than urban commuters. Plus surplus is very low her in Iowa. 
 

Ya know it is fun talking about it and “dreaming”. Lol.

I have a manual transmission CT5-V Blackwing LT4 on order.  Can't wait for it to arrive!  Gm could never make enough Escalades with that motor to satisfy demand.  Good for the General to get as many rumbling gas guzzlers on the road as possible before it is all EV.

Maybe just go old school, with more modern touches to make it street able, 1000hp right out of the crate, normally aspirated.

Lingenfelter and Hennessey have been doing GM full warranted supercharger installs for years on LS and LT engines.

Ya, I know but the cost is what has “per say” kept me from doing it. The last I checked Hennessey was some where in park of an extra $30k.  Heck that’s a nicely used Camaro SS. 
My friend who owns all the superchargers in Yankton, SD told me a doctor up there had an Cadillac Escalade done by Hennessey. I think he was bragging that he paid over $127k for it to be all done.  This was around 2015 and it was a short Escalade not the long wheelbase. I thought price was outrageous.

Oh yeah, my point was that GM has been doing supercharging (Buick 3800s too) and when they do it from the factory and not through those guys, the price will be much much less.

I agree, and Oh yes the indestructible 3800!!  Well not really but man those engines could run. Went through 3 of them on my side of family and father in law owns trucking business and he went through 2 himself. Well over 300k. Non with superchargers though. 
I remember my sophomore year in high school Pontiac released the wide body 97 Grand Prix. Then year later came out with the supercharged GTP. Sexy car and fast for those times.  They had no problem beating GT mustangs back then.

@KARNUT…..you were probably in love with the late 80s and 90s GM 4.3L and 3.8L engines. I know I was!!  Either by turbos and superchargers. They were just good old fashioned pushrod engines.  No cylinder deactivation or other “gremlins” to mess up the engine. My moms 2001 Impala averaged over 30 mpgs running 65 down the highway to her work all day long.  Now when you pushed it harder it was mid 20s but that was because of the 4 speed transmission hindered it.

In the 80s my wife drove a modified 74 impala with a 454. It became my toy she got a cutlass wagon with the 5.7 diesel. Then an little olds starfire with the V-6. Then a holiday 88 olds I believe with a 301 V-8. The 90s Geo- Toyota, ford mini van, Lincoln, mercury sable. New 94 impala ss and a 94 Z-28 as a daily. 98 mustang my son got the Z-28. She hated the V-6 mustang a 99 ford contour V-6. 2001 Acura intagra type r, still has it. 05 Elantra GT, my grandson dives now, 2010 Mazda 3, 2011 Genesis, will not part with. The 70s 68 impala, 69 impala, 74 nova, 75 ford elite. Me and my brother traded nova, ford. 74 Mazda cosmo. Figured I’d compete her list best I can recall. Doesn’t count me or the toys.

I’d buy a supercharged V8 if it was offered. We’ve owned a new Land Rover Range Rover Supercharged V8 since June 2015. It’s rated at only 525hp and definitely has the power to take off and move right along. And the fuel economy currently reads 18.5 mpg on the long term gauge. Only problem we’ve had was a leaking AC Freon hose that was replaced under warranty. And 8 cylinder power all the time, no Dynamic Fuel Management bullshit.

I wanted a Pontiac Grand Prix GTP coupe when those things were I out.  But, GM decided to kill it.  I loved Pontiac until their demise.  Wanted a Solstice hardtop with the 2.0 turbo, but I doubt I would've fit in it since I'm too tall for a C7.  Also loved the Trans Am WS6 with the Firehawk package. 

 

A little supercharged engine that impressed some people was the LSJ.  It was a 2.0 supercharged Ecotec.  It was in the 2006 Cobalt.  I was beating stock Mustang GTs in the 1/4 with that car, but I had to get the hole shot.  That car would pull from the start, but the Mustang would start reeling it towards the big end of the track.  It wasn't enough by the end though.  It would trap a fat speed, but I was covering the 1/4 quicker.  That was bone stock for both cars.  Stock I also got that car into the 130 MPH Club on the Bonneville Salt Flats.  Took a few passes to figure it out.  I was trying to shift into 5th before the end of the track to take advantage of torque, but it was costing me speed.  Did some math and decided to go for it.  Left it in 4th and bounced off the rev limiter right after crossing the 1 mile line.  Average 131 MPH and got into the club.  4th was got up to 134, iirc.  Rev limiter was 6500 rpm.  SAE rated 205 horse/200 torque, but everybody that owned one believed the car was underrated. 

 

GM was making fun cars 15 years ago.  I wish they'd do it again.  A turbocharged Trax SS with AWD would be a little toaster that could.  Equinox Sport was well conceived, but poorly executed.  A V8 Traverse with the 5.3 and AWD.  And, an LT5 Silverado in both street trim (SS) and offroad (ZRX).  Somebody call Mary and tell her she's fired.  I should be running the show, lol (Bad idea.  I'm too much of an a-hole.)

Then in 2008 they switched over from a supercharger to a turbo and the Cobalt went even faster!!  They were a stealthy little car. You also had the Impala SS with the 5.3L and it was a sleeper and munch GT mustangs stock for stock. I had the Trailblazer SS and loved it. AWD and 6.0L would really scoot!  Then from 03-06 was the SS Silverado. That truck had one of the best stances in my honest opinion. Just looked sinister, yet “classy “ all in one package.  
 

I just bought a new Traverse Premier Redline for my wife in September and the 3.6L is nice, but I would absolutely love a 5.3L in it.  The ride on the Traverse is amazing.
 

This EV push right now will fade.  The surplus isn’t there and neither is the demand.

My buddy has a 2019 Range Rover Sport with Carbon Fiber package. Loves the vehicle. I have to say man does it ride nice. The thing moves really well for the amount of WEIGHT those things have.

    • Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package. 
    • So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.  
    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
