V-Max Flat Tappet For maximum increases in low-end torque, engine vacuum and improved idle quality, our newly developed and newly patented Rhoads V-Max Variable Duration Lifters are the answer. They increase low-end torque and engine vacuum up to 50% more than Orginal Rhoads Lifters...and they rev higher too. This makes them the best choice for hot street, performance marine and all racing applications. Typical vacuum increases range between 3 to 5 inches at idle when used with bigger cams. They are fully adjustable and require an adjustable valve train. Adjustment is similar to solid lifters. Simply use a feeler gauge to adjust the exact amount of lift reduction you want, anywhere from .010" to .030", and that is exactly what you get at idle. Duration is reduced between 5 and 20 degrees at .050" lift depending on the adjustment. As the rpm increases, so does the lift and duration. Full restoration takes place at approximately 4000 rpm. For engines equipped with adjustable valve trains, Rhoads V-Max Lifters are definately the best choice. They are 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.
