Anyone know what power the stock 5.3l is putting down with the whipple?  I’m thinking of taking the 5.3 out of my 2020 build and drop it in a Jeep JK.

Ya'll worry too much. A little annoying.    I'd deny my warranty if i was GM. I boosted intake pressure by 8lbs. Unlocked an ecm that was specifically hard to crack, and retuned parameters s

Havent heard anyone mention a cold air intake and a supercharger together. I installed the GM performance intake. I liked the rotofab and the afe, but with how the intake tube and the maf is mounted,

My experience with superchargers and intakes is that a CAI will make a supercharger whine louder.  Is that the case here?

I was hoping for some increased whine as a secondary benefit, but i didnt notice much difference.

 

At idle and low rpm i have a slight noise that sounds like the tensioner. Hollow sounding "ting" ..... pause.... "hollow "ting".... pause .... repeat. Definitely seems like it'd be belt related, but could maybe be internal noise to the s/c compressor. Hasn't bothered me enough to dig into it. 

 

Once you start getting into the throttle a bit, or a lot, she screams though. An evil and simultaneously heavenly scream.

Anything that'll make her scream like that when you make her go is worth it, imo

Definitely will improve airflow. Mainly installed as I'm looking to get a functional ram air hood evetually, at which point ill take the plastic top cover off. The hoods funnel air and dump right over the top of existing filter location.

Was this an easy install, no mods to the intake tube?

How are these superchargers holding up on your different trucks? Reliability issues? Was anyone able to unlock/tune the 10 speed controller?

I have had no reliability issues with the SC or related items at all.  The only issue I had was the high pressure fuel pump failing, but that is a common issue, apparently.  The canned tune isn’t the greatest, there is a little surging on acceleration and I have an issue where the cruise control will run away on hills with a load.  Generally, it is just awesome, though.

 I am going to have all of the DFM related items in the valve-train removed, replace the cam and have it custom tuned, as soon as I find someone I can trust to do it.

Any updates on how yours is holding up in regards to trans and motor in general?

I have had no issues other than the high pressure fuel pump failure, which didn’t fail due to the SC.

I have a 2018 gmc 6.2 denalli 4wd that ate the cam so it got a tsp stage one cam to go with the LT’s, cai and 6th gen whipple 3.0 sc.  install was way more then expected as tuning both the engine and trans was a momma and I needed to install a high flow fuel pump as well as lt4 injectors.  Although faster it only ran 135+ in the 1/2 mile.  Was scheduled to get it to the 1/4 mile this Saturday but the rear diff blew up and apparently the 3.73 gears I had installed over 30k miles ago are out of warranty.

Dyno showed almost 600 whp.  May not get it back to the drag strip till fall of 25 and let it sit for a few months as the 900hp 69 Camaro has run substantially over budget😢

      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.

      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

      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.

      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?
