I hate to be that guy, but if you have to ask on a forum about whether something will go 55 plus, not only can't you do it, but you probably shouldn't. Nopeds in particular have terrible dynamics over 45.
Build the best bike you can and be happy with how fast it goes. Probably 45 for the parts you listed.
If you really want to go 55 on a QT, your best bet is to read this thread and learn it.
