Yes;
That at least is what I am planning to do. I have a new poly tank. When
I remove the top of the seat back and get the old tank cut out I will take
the poly tank and do some fit ups. Then I will more or less copy the
plastic tank's configuration doing some optimization and then raise the
top approximately 2". Prior to doing that I will mock up the raised
configuration of the whole mess to make sure there are no hidden
gotcha's. I still need to talk to some people around here to see what the
optimum thickness of aluminum (or aluminium?) to use. I did an analysis
and a 3/32" thickness of Al would give me a tank about 5 lbs heavier in the
stock configuration. I did receive a photo of a tank on the internet but
no specifics came with it. Any further input would be appreciated. A 2"
height increase would give about 3.5 extra gallons and raise the angle of
the seat belts over the shoulder slightly which had been an item of
concern in the past.

steve, have you considered a kevlar or CF tank, the way i was thinking of
going was doing a blank of the bigger tank
out of foam,try it in place, then assuming all is good do a few layups of
kevlar or carbon over the whole thing, putting the fittings in place
during the layup, then just melt the foam out later using mogas. The carbon
is easier to work with, but i have concerns it
may be TOO stiff. thats why i thought kevlar matt may be better, or a kevlar
carbon weave cloth, with a vinyl ester resin system
that is chemically resistant. this would probably give you a tank about 2/3
the weight of the original with the extra capacity.
just a thought.
