DeatschWerks: Fueling Evolution for Record-Breaking Power
Every tuner knows a simple rule: air is potential, but fuel is realization. You can bolt on a massive turbocharger, but if your injectors can't deliver enough fuel or your pump sags under load, your engine will turn into scrap metal in seconds due to a lean condition. DeatschWerks (DW), based in Oklahoma City, specializes exclusively in high-performance fuel systems. They don't do suspension or exhaust. Their sole mission is to keep your engine fed.
ATOMIC-SHOP is an official dealer of DeatschWerks. We offer comprehensive solutions: from the legendary DW400 series pumps to high-precision injectors capable of running E85. This is the choice for builders aiming for 500, 800, or 1200+ horsepower who demand OEM-level reliability.
Dynamic Flow Matching: Why DW Injectors Are Superior
Many companies sell "performance" injectors. Often, these are just drilled-out stock units. DeatschWerks uses Dynamic Flow Matching technology.
What does this mean? Standard injectors are balanced statically (at 100% open duty cycle). That's easy. But in real life, an injector opens and closes thousands of times a minute. DW tests and matches injectors in sets by measuring performance at multiple pulse widths: 2ms (idle), 4ms (cruise), and 10ms (acceleration).
The Result: You get a set where every injector delivers the same amount of fuel not just at wide-open throttle, but also at idle. This ensures smooth engine operation, no vibration, and easy tuning.
The Ethanol Era: E85 Compatibility
Ethanol (E85) is the cheapest way to get 105+ octane race fuel performance. But ethanol has two downsides: it requires 30-40% more fuel volume, and it is hygroscopic (absorbs water), which causes corrosion.
All DeatschWerks components (pumps, injectors, regulators, lines) are engineered for aggressive E85 environments. Pump internals are anodized, injectors use stainless steel, and seals are made of Viton, which does not dry out or crack from alcohol exposure.
Fuel Pumps: DW vs. The Competition
The heart of the system. DW offers a wide range of in-tank and in-line pumps. A key feature is "Fitment." DW pumps often drop into factory baskets without the need for zip-ties or hacking up the housing.
| Model | Flow (LPH) | Features |
|---|---|---|
| DW200 / DW300 | 255 / 340 LPH | Compact size. Ideal stock replacement for Stage 1-2. Quiet operation. |
| DW65c / DW35c | 265 / 350 LPH | Compact Series. Designed for complex, shallow fuel baskets (Subaru GRB, GT-R R35, Evo X). The only bolt-on solution for these cars. |
| DW400 | 415 LPH | The Monster. The highest flowing in-tank pump that fits stock hangers. Outflows the Walbro 450 but lacks the bulky bottom bell, making installation easier. |
| DW440 Brushless | 440 LPH | Brushless technology. Less heat, longer life, requires its own controller. |
Complete Approach: Lines, Fittings, and Regulators
DeatschWerks understands that pumps and injectors need to be connected. They offer:
- Fuel Pressure Regulators (FPR): The DWR1000/2000 series. Uses advanced diaphragm materials that maintain stable pressure even under rapid boost changes.
- Fuel Filters: Reusable stainless steel or micro-glass filters. They trap dirt down to 5 microns, saving expensive injectors.
- PTFE Lines: Teflon hoses that do not permeate fuel smell into the cabin (unlike standard rubber) and last forever.
Surge Tanks: Eliminating Fuel Starvation
For circuit racing and drifting, DW developed modular Surge Tanks. When you corner at 1.5G, fuel in the main tank sloshes to one side, starving the pickup. The engine gulps air and can fail.
The DW Modular Surge Tank system stores 2.5-3.5 liters of fuel in a separate reservoir, housing powerful DW pumps inside. This guarantees consistent fuel delivery under any G-force condition.
Frequently Asked Questions (FAQ)
Do I need a tune after changing pumps/injectors?
Absolutely. Installing larger injectors without ECU remapping will cause the engine to flood, fail to start, or run poorly. Installing a high-flow pump can also overcome the stock regulator, raising rail pressure, which also requires tuning correction.
What is "Injector Data" and why do I need it?
In every DW injector box, you will find a flash drive or link to data. These are calibration tables (Latency, Dead Time, Flow Rate). Your tuner simply copies these numbers into the tuning software. It saves hours of dyno time and ensures perfect drivability.
Are DW pumps noisy?
DW rotary pumps (200/300 series) are known for being quiet compared to competitors like Walbro (which have a characteristic whine). However, extreme performance pumps (DW400) will be audible at idle; this is the trade-off for massive flow.
