Fuelab has been a part of our program since 2010, and has been there for 8 of the 9 championships in my car. Their products and support are second to none. The pumps are light weight, and very low amperage which really matters when your race car demands on so many electrical components. My 41404 is so efficient and perform so well, I'm feeding 800+ horse power with the pump set at half speed. With a weight of 3750lbs w/driver, and a naturally aspirated 434ci Small Block Chevy, my best ET is a 9.85@135mph -Andy Warren
