Why is this the case, and what can we do about it? Due to the nature of direct injection and how it operates in a GM application, it simply isn't a matter of adding aftermarket injectors and turning up the fueling like we often can with port injection, given that DI fuel pumps in GMs LT engines are camshaft driven. Michael Sitar of TooHighPsi has an option for GM LT V8 owners that can take the LT1 and LT4 variates beyond their 600hp and 700hp ceiling imposed by the stock direct injection system without dealing with camshaft complications, and that is done by adding port injection and tapping into the factory GM ECU's CAN Bus data stream. At this stage customers are up in the 1400hp regions with some drag applications with plenty of margin left in their injector duty cycles for future development and additional power potential. ------------------------------------ TIME STAMPS: 0:00 - Direct Injection Problems 0:50 - LT1 Example 600hp 1:18 - LT4 Example 700hp 1:27 - Injector & Pump Options 2:03 - TooHighPsi Port Injection 2:37 - Packaging: Port Plate 3:08 - Injector Length 3:30 - Fuel System 3:58 - Fuel Management 4:46 - CAN Bus Integration 5:32 - Factory ECU Considerations 6:32 - MAF Curve 7:33 - Fuel Calculations 8:05 - Outputs 8:44 - Injector Sizing 9:02 - Thanks Michael! 9:20 - The More You Know, The Faster You Go! ------------------------------------ FREE LESSONS: 🏎 Want to learn how to EFI an aftermarket ECU like a MoTeC, Haltech, Link, AEM, Syvecs, EMtrom, Maxx, Ecumaster, MegaSquirt, Arduino, MicroSquirt, Holley, FuelTech, ME or something else completely different?
