So I noticed after playing with a drummer that when I sing with a rasp it restricts how loud I can sing. When I sing normally I can sing louder... Could somebody comment on this please?

Your rasping from your throat and constricting too much. It makes sense as less air can move through your throat (even though you are increasing pressure). Instead, sing relaxed and learn to rasp with either false cord use or by vibrating your soft pallete. Both techniques are more healthy and sustainable and begin with being relaxed.

ya probably using your throat. You should think of it as "rasping with your vowels", and not your muscles.
