Ram 1500 Supercharger Buyer's Guide: eTorque or Not

Most Ram 1500 supercharger content you'll find online is a brand shootout: Whipple vs ProCharger vs Magnuson, pick a favorite and move on. For the Ram 1500 right now, that comparison doesn't exist. There's exactly one supercharger maker building a complete, documented kit for the 5.7L HEMI, and the real decision isn't which brand to buy. It's which version of that one kit fits your specific truck.

RideBuildList earns commissions from some retailer links.

The kit is Whipple Superchargers Gen 6 3.0L Twin-Screw Supercharger Kit (Non-eTorque), and it comes in two versions built around one question: does your truck have eTorque or not.

eTorque is the fork in the road

eTorque is Ram's mild hybrid system, a belt driven motor generator that helps the engine start, adds some torque fill at low RPM, and runs the auto stop start feature. It became available on the 5.7L HEMI starting with the 2019 DT generation (new body) trucks, and it's an option, not standard on every one of them. Check your build sheet or window sticker before you buy anything here, because the two kits are not interchangeable:

• Whipple Superchargers Gen 6 3.0L Twin-Screw Supercharger Kit (Non-eTorque) is built for trucks WITHOUT eTorque.
• Whipple Superchargers Gen 6 3.0L Twin-Screw Supercharger Kit (eTorque) is built for trucks WITH eTorque, and includes the extra brackets and relocation hardware that hybrid system needs.

Whipple is explicit on both product pages that the two aren't cross compatible. Buy the wrong one for your engine and it will not bolt up.

What each kit claims

Both numbers come straight from Whipple's own product pages, measured at the wheels on 93 octane. The catalog has no independent dyno test backing up either figure, so read these as the manufacturer's claim, not a verified result your specific truck will match. The eTorque kit claims the bigger number, but there's no third party test on file confirming either one.

The CARB numbers, and why they matter

Both kits carry their own CARB Executive Order: D-231-145 and D-231-115 for the non-eTorque version, D-231-152 for the eTorque version. Whipple publishes those numbers on the product pages, which is a specific, checkable filing rather than a vague "street legal" claim with nothing behind it. That's worth something. It is not the same thing as a guarantee that your truck, in your state, with your inspection program, is fully compliant once it's installed. Emissions and street legal rules vary by state and change over time. Check with your state's program and talk to a shop or an attorney who knows your local rules before you commit. Nothing here is legal advice.

What it costs you beyond the kit itself

Both kits carry the catalog's hardest install difficulty rating, a 5, with 12 to 16 hours of labor estimated for a professional install. That time range is an estimate in the catalog, not a number Whipple itself publishes, so treat it as a planning figure, not a promise. The job touches fuel delivery, the intake, charge air plumbing, and on the eTorque kit, the hybrid system's wiring and brackets too. This is not a weekend job for most driveways. Find a shop that has installed this specific kit before, not just a shop that has done superchargers in general.

The live price on each kit shows at the link above and changes, so this guide isn't going to freeze a number that might be wrong by the time you read it. Budget for premium fuel after the install too. A supercharged HEMI is not running on regular anymore.

Questions worth asking before you buy

• Does my build sheet actually show eTorque, confirmed before I order, not guessed from memory.
• Am I running 93 octane every tank after this, not just when I remember to.
• Do I have a shop lined up that has installed this specific Whipple kit before, not just superchargers in general.
• Does my state's emissions program accept a CARB Executive Order number, or does it run its own separate approval process.
• Am I ready for the kit price plus a full day or more of professional labor on top of it, not just the kit price alone.

What the catalog doesn't cover yet

If your Ram 1500 is the previous generation body style, built before 2019, this catalog has no supercharger listed for it right now. Same story if you're on a 2025 or newer Ram 1500 built on the newest platform. This guide only covers the 2019-2022 DT generation 5.7L HEMI, because that is what is actually active and priced in the catalog today. If your truck falls outside that window, the honest answer is that there isn't a supercharger option here yet for you, not that one exists and we're holding it back.

What to skip

Watch out for generic "universal" supercharger kits or pulley only "power packages" marketed for the 5.7L HEMI that don't name a specific CARB Executive Order and don't tell you up front which eTorque configuration they fit. If a listing can't say flat out whether it works with eTorque, either the seller doesn't know or is hoping you won't ask. Either way, that is not a decision worth making on a guess when a wrong purchase means a kit that will not install on your engine at all.

Bottom line

This isn't a five brand comparison because the market for this platform isn't there yet, at least not in a form the catalog can verify and stand behind. It's really a two question decision: does your 2019-2022 Ram 1500 have eTorque, and are you ready for a professional grade install plus a real jump in fuel cost. Answer the eTorque question first. Everything else follows from that.
