SDI camshaft difference 47kw-50kw

Hello, i've bought SDI camshaft from 47kw caddy for my mk4 1.9tdi 81kw AHF. on 47 cam it's written ftw10, on 50kw its ftw7. Does anybody know the difference between those cams? Lift and phase? Which is better? Thanks for answers.

it will be not a HUGH difference , IF you whant better cam go buy dbilas or nps

The sdi cam do little better spool up and low rpm torq it opens the ex valve little sooner

Yes i understand, thanks. But I want to know between these two, this 47 cam looks like it has sharper cam like 260. On 50kw the cam is duller. So which better?
