So there comes a cross roads when a direct injected LT1/LT4 will require more fueling. This is because we are using fuels like E85 to make more and better/safer horsepower. But this fuel requires more of fuel system to move it. To add this fuel we need to upgraded the fuel system, substantially if you're wanting to make over 900rwhp.
Most go with the cheaper option and that is methanol injection. This allows us to add more boost since we use it to fuel the high side fuel system. But it does have its limits. Also, there is a limit of methanol that you want to rely on to keep your car happy, and also to a point that if the system fails you don't want complete destruction. Every tuner will vary on this. This is the simplest option, it just takes a little more thought being that you have to fill an additional tank and maintain the pump throughout the years.
Some tuners go with larger injectors and larger high side fuel pumps, but these also have a limit. The cost of them, we feel there's better options out there. We prefer to add port injection to the direct injection system to make it a dual fuel system. You will have 16 injectors total, making it a sufficient fuel system for an ample amount of HP. This is something to consider when planning out your build so you don't waste money on the other two options. You can save money by doing this step first.
With the delays of ECUs we are working on an another system to support our customer HP needs. So keep an eye out on our social media platforms. I will be sure to announce.
