What Does This Do?
The DW 300 (340 lph) sits between the stock pump (~255 lph) and the DW 400 (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 DW 400. Like all Deatsch Werks 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 DW 400.
