The LS1 engine, renowned for its performance and tuning potential, has become a favorite among car enthusiasts. One of the most effective ways to boost horsepower in these engines is through E85-compatible fuel pump upgrades. With the right modifications, drivers can see gains of over 40 horsepower, making this an appealing option for those looking to enhance their vehicles.
Understanding E85 Fuel
E85 is a high-performance fuel blend consisting of 85% ethanol and 15% gasoline. It offers several advantages over traditional fuels, including higher octane ratings and the ability to produce more power. However, to take full advantage of E85, specific upgrades are necessary, particularly concerning fuel delivery systems.
Why Upgrade Your Fuel Pump?
Upgrading the fuel pump is crucial when switching to E85 for several reasons:
- Increased Fuel Demand: E85 requires more fuel than gasoline due to its lower energy content.
- Higher Flow Rates: A compatible pump can deliver the necessary flow rates to maintain performance.
- Improved Reliability: Upgrading ensures that the fuel system can handle the demands of high-performance tuning.
Choosing the Right Fuel Pump
When selecting a fuel pump for E85 compatibility, consider the following factors:
- Flow Rate: Ensure the pump can deliver enough fuel for your power goals.
- Compatibility: Choose pumps specifically designed for E85 to avoid corrosion and failure.
- Brand Reputation: Opt for trusted brands with proven performance in the LS1 community.
Popular Fuel Pump Options for LS1 Engines
Here are some popular fuel pump options that are known to work well with LS1 engines running on E85:
- Walbro 450lph: Known for its high flow rate and reliability.
- DeatschWerks DW300: Offers a good balance of performance and price.
- AEM 50-1200: A versatile pump that supports high horsepower applications.
Installation Process
Installing a new fuel pump can be a straightforward process if you follow these steps:
- Gather Tools: You’ll need basic hand tools, safety gear, and possibly a fuel pressure gauge.
- Remove the Fuel Tank: Safely disconnect and remove the fuel tank to access the pump.
- Replace the Pump: Remove the old pump and install the new one, ensuring all connections are secure.
- Reinstall the Tank: Carefully put the fuel tank back in place and reconnect all lines.
- Test the System: Turn on the ignition to prime the pump and check for leaks.
