For maximum increases in low-end torque, engine vacuum, and improved idle quality, Rhoads V-Max variable duration flat tappet lifters are the answer. These unique lifters are designed to significantly increase low-end torque and engine vacuum. This makes them the best choice for hot street, performance marine, and all racing applications. Typical vacuum increases range between 3 to 5 in. at idle when used with bigger cams. They are fully adjustable and require an adjustable valvetrain. Adjustment is similar to solid lifters--simply use a feeler gauge to adjust the exact amount of lift reduction you want, anywhere from .010 in. to .030 in., and that is exactly what you get at idle. Duration is reduced between 5 and 20 degrees at .050 in. lift, depending on the adjustment. As the rpm increases, so does your valve lift and duration. Complete lift and duration restoration take place at approximately 4,000 rpm. V-Max series lifters are also particularly suited for racing applications with vacuum rules. You can run more cam than your competition while still meeting vacuum requirements, giving you the performance advantage.
