Well, It was alot of work, some trips to the machine shop and alot of welding. If you arent able to do all that I wouldnt even bother with this project. Yes it works well, better than I thought it would. But the only reason I decied to try this was because I had access to a machine shop and a sheetmetal shop and my dad is a welder. As far as modification to the blower there was none, the discharge plate ontop I cut off then threaded ring and the lip that was under it. to the inlet I cut off most of it, boxed it up and put a real short 3 inch nipple on the back. If you are doing it like I did you dont need a 4" cowl hood, mine even still rubs just a touch.
As for dyno numbers, I got a tweecer comin in soon, Im gonna self tune it a little bit after all this snow and **** clears up then take it to the dyno.
I'll have some in car vids up once the snow is gone also.
