Well, they are really too cheap now to mess with that. PM for a delivered price on a shiny new one!, you'll be surprised. I've opened them up, but never went very far -- it seems you would have to cut welds, and then re-weld to accomplish anything, though adding some extra support is a good mod to a new one, or before it cracks at the mount. pacrimdm@msn.com
I just finished remodeling a toaster for iceracer17. Its a few pounds lighter and Im sure it will flow a little better than the one we used on the dyno. A bread slice slot wouldnt be a bad idea. LOL
