Re: Solid flat tappet VS solid roller
After reading that it seems a flat tappet can have a higher acceleration rate while a roller can have higher peak velocity and run more lift.
I'm curious about the duration comment Mike as I've heard that before. I think with similar .050 duration a roller cam can still have a significant advantage since it can have significantly more lift. Take away the ability to use more lift and the roller advantage is crippled IMHO. The duration at higher points of lift should be more on the roller lobe with more lift as well. How much of that could possibly be made up by a flat tappet lifter at the valve where it counts I couldn't say???
