Just ordered my Edelbrock E-Force Supercharger from Jegs.Edelbrock hasn't even started shipping them yet.ETA is June 28.Can't wait to give that L9H about 7lbs of boost.The kit comes with a 3.750 diameter pully,every .250 decrease in pulley diameter gives 2 more pounds of boost.Since the injectors are able to flow E85, the injectors along with the fuel pump are more than up for the job of providing plenty of 93 octane.

This is a video showing how the 6.2L sounds with headers and a corsa catback. The crew cab is my 6.2L, the 2005 extended cab is a 5.3L with a magnaflow muffler welded in.

Do you gave to run 93 octane with that supercharger? Id like it to but hate to fill up with 93 all the time.

I'm pretty sure you will have to use the higher octane all the time.That is what the Edlebrock Tech guy told me when i talked with him before i place my order.I'm going to use my truck for a weekend venicle.I have a beater that sips gas that i drive the rest of the time

This is the latest picture of my recently purchased GMC Sierra SLT. A neat little thing the previous owner did was,he put stainless steal 6.2 emblems next to the Sierra emblems on the doors and tailgate.I'll post a close up picture of that soon.

Just ordered my Edelbrock E-Force Supercharger....

 

 

I'm jealous! I'd love to be able to supercharge my truck but I just can't swing the $$$. Oh well.... I can't complain. The stock 6.2 is no slouch.

 

Enjoy your truck. It's nice already and getting nicer all the time.

Has anyone installed a PVC oil catch can? Any downside from this?

Just got back from our first long (3,770 miles-3 weeks) trip towing our travel trailer (wieght around 6,000 pounds) Real pleased with the 6.2L and NHT package. We went from Louisiana to Georgia, then to North Carolina (Ashville) and up some pretty steep grades (7%). Then headed up I-81 and on to New Jersey to visit our daughter and grandkids. Then back to Lousiana. Drove mostly 63-65 mph and averaged 9.8 mpg on the way north and 9.6 back south (headwinds). Used mostly 93 octane gas with a couple of 91 octane tanks along the way. This truck is a towing beast!

Good to hear MPG numbers like that seeing as how that's the size tt I am looking into for next year and was expecting worse, honestly.

 

Currently my truck, Non-NHT but 6.2, doesn't even know my pop-up is behind me. I pulled down 14.5 MPG pulling it a few weeks ago through some of Northern Michigan's hills but I also had a full load of goods in the bed, the a/c on and the cruise set at 72 MPH.

Are you planning on installing the supercharger yourself? If so, let us know what challenges you faced. Edited by Pdub_28

If so, let us know what challenges you faced. Edelbrock offers two warranties to cover any motor or trans damage from installing the supercharger,but it has to be installed by an ASE certified mechicanic or GM Dealer or Authorized Edelbrock installer,so i'm not going to do it myself.The Edelbrock Certified shop in my area want 1500.00 to install it.Then he wants another 650.00 to tune it over and above the tune that comes with it,and this will void the warranty.He tells me he can get 35 to 45 more horsepower at the wheels with his custom tune.I think i'm just going to have him install it with the provided tune and drive it that way for a while.I don't want him to put a tune on it that puts it on the ragged edge of breaking ring lands off of pistons if i get some bad gas.It will be delivered tomorrow.I have a question on downloading pictures to this site.What is the best way? I have been struggling to post pictures,i'm not sure if pix of my truck are even viewable,can you see the one i put up? I can't !!!!

The resizing link worked better than i thought,it made my pictures viewable without me doing much at all.Thanks for the help

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      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.

      Active Grille Delete

      By jaszr2 · Posted

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
