Ripp has a few vids on you tube,the one that impressed me was the guy in the desert doing doughnuts around his mate.
just before you go & further modify the charger after the stock install,go check with a good motor builder cause i'm sure your going to need different valves & springs & decompress the engine alittle,that doesn't cost much in parts but the labour may hurt. 12 psi may take it up to around 17:1 comp ratio which means you could blow your heads & cost lots of dollars. I know with Turbo's,you cant leave the motor stock & double the comp ratio without head work & exhaust,just keep that in mind.
Maybe we can do a group buy cause i'm thinking of buying one.get it cheaper
