John,
I was looking at the RB Racing Turbo VMAX article in the '89 issue of
Cycle World on page 40 ... Of course in that article Robert Behn, (the
"RB" part of RB Racing etc), estimated a theoretical 300 horsepower
was possible from his product. However ......... in the same issue ..
starting on page 27 ... Cycle World was doing their annual "Built for
Speed" series and the RB Turbo VMAX was a contender in that
competition. In that article they mentioned that the RB Vmax was a
"last minute" deal ... after their "original entry" ... a "customer
owned" turbo Harley was pulled. In this article he did get to "test"
how fast his creation would go and I will quote exactly two paragraphs
describing it's performance from the Cycle World article.
start quote .... (1/4 mile test)
The turbo V-Max ?? In spite of the best efforts of RB Racing's Bob
Behn, who rejetted the bike's complicated carburetion system six times
during the course of the day and who tried the bike both with and
without it's V-boost induction system, it managed no better than a
10.91 second, 125.17 mph run, popping and banging the whole way. We
should note that our stock 1988 test V-Max turned a 10.88 second,
125.00 mph quarter mile pass when we evaluated the machine in last
August's issue.
end of quote ....
start quote .... (top speed test)
Finally came the turn of the RB Racing Turbo-Max, the jetting of which
RB's Bob Behn still was struggling with. No progress there, and no
luck, either: The bike's megamotor holed a piston in the hot,
dry-lake-bed atmosphere before it got up to speed, giving RB last
place in the top-speed runs as well as in the dragstrip competition,
and earning CW's unofficial Hard Luck Trophy.
end of quote ....
Soooooooo ....... so much for running lean ... I suppose that is why
they are trying fuel injection now and their price has gone up from
$3295 into the $7K range ...... (apparently the cost of a case of
pistons ... expended while setting up boost enrichment tables ......
LOL ;) Hmmmmmm .... have to visit the Mr. Turbo site ... they still
have a Vmax kit I think ....
