Well PipeMax says I need .809 lift minimum to have peak hp at 6500 rpm and it recommends more lift than that. PipeMax does seem to like a lot of valve lift though and I don't fully understand the assumptions that went into that program. The engine builders that follow that program though seem to get pretty good results so I think it has to be treated with some respect.



Yeah when I run my pipemax program it always calls
for a big lift, I have always figured its high but
I've never tried their suggestion on lift(max)
