Why Install This?
Benefits
- Moderate install — doable in a home garage with some mechanical experience
What Does This Do?
The DW300 (340 lph) sits between the stock pump (~255 lph) and the DW400 (415 lph). It's the right choice for mildly supercharged builds running 6-10 PSI on pump gas — enough headroom to feed the engine safely without the cost of the larger DW400. Like all DeatschWerks pumps, it's a direct drop-in for the stock pump. The 340 lph supports approximately 600 HP on gasoline. If you're planning to run E85 or exceed 600 HP, step up to the DW400.
Fitment Notes
Fits 2008-2023 Challenger all HEMI engines.
Tune Required
This part requires an ECU tune to function correctly. Without a tune, the engine computer won't adjust for the new part, potentially causing poor performance, check engine lights, or engine damage.
Technical Details
Mid-range fuel pump upgrade, 340 lph. Good for mild-to-moderate forced induction.
