A 'blast from the past,' the Kawasaki Z1R with the ATP (American Turbo Pak) factory bolt-on kit, making the VMax RWHP if your VMax was done by someone who can tune the Stage 7/Kerker 4-1 setup to get 130 RWHP.

A great read, and be sure to read the comments after the article from present and former owners who all say, 'scary-fast,' probably due to the unmodified stock frame and the sudden onset of boost. Being equipped with a Rajay turbo which had a provision in the plumbing to modify the boost via a simple screwdriver, and without sufficient internal mods (in the first version) to allow the engine to live at anything over minimum boost, these quickly grew a reputation as 'hand grenades.' Fast, but no longevity in the hands of an enthusiastic owner who used their screwdriver to max-out on the boost.
Locally in south FL, I had several acquaintances who ran turbos on their XS-11 Yamahas, built to accept the increase in HP, and they were faster than any stock bike of the day.
I recall being on the road to the beach to the ocean one night, and the only thing on that road were land crabs going back and forth across the road, moonlight, and us. I was on a '83 KZ1000J with 33 Mikunis, a Kerker no-baffle 4/1, GPZ1100 cams, and Dyna ignition & coils. He was on a Kawi 750 Turbo, and he walked that front end high in the air through first, second, and into third before he put it back down. It was quite a sight to see. The turbo bikes are impressive producers.
Another of my acquaintances from that time, Mark Moisan, (early 1990's) ran an air/oil-cooled GSXR 1100 equipped with a turbo, he tuned it to produce 405 RWHP at Daytona's HP SHootout at the old American Motorcycle Institute (AMI) contest. When he was invited by Sport Rider magazine to a builder special contest in CA, he took that bike and went 229 mph before the boost blew-loose the carbs! I've mentioned this guy in the past, his wife could and did ride the bike to local bike nights w/the boost turned-down. There is some controversy on the internet over his use of an aftermarket kit to get his results, and if he gave credit where credit may be due, but it was a starting point, and he took it farther than others did at the time. Now there are turbo Hyabusas and Kawi 14's besting that by quite a bit, but his work was well-before that, and he 'made the numbers.'
