Drop In's

Hey guys, I don't know if this picture works if not here's a link https://www.newschoolers.com/web/content/pictures/id/109974/

I built this drop in a while ago. It looks really steep there but there is a peice that attatches onto the bottom to mellow it out. The ply wood wasn't on it yet and it wasn't done. I've used it a few times and it just doesn't give you enough speed. I was just wondering if anyone had any ideas on how to make a better drop in. Thanks
