Hi, only thing I reall y know is they were sold to me as stage 2 cams and fitted for me by Regal Autosport. I;ve attached a couple of before / after RR maps so you can see how much of a difference they made.
All I can say is that the miggers who used to come to Castle Combe were very impressed with how smooth and progressive the power came in. I used to use my car for odd track days and as the family shopping trolley and they were fine for road use as well. Sorry I can't give you any duration / lift specs.
