Well, after all the rumours and passing comments as to the existance of a turbo Zeal it seems that Rapid Bikes have tracked it down and done a little expose in their latest September 2006 issue. I've scanned it up just for everyone who at one point thought about doing something a little crazy with their FZR's.
Not many details on the mechancials but it appears to have used quite a few FZR600 parts to beef up the engine & clutch to take the increased power. Oh, and as for power...

105 RWHP (45ft-lbs) @ 18,000rpm w/ 18 psi boost.
12.7 second 1/4 mile @ 118mph.
