The Sierra Nevada Website gives enough information on the Torpedo that you should be able to come up with a recipe pretty easily.
alcohol content - 7.2% by volume
yeast - Ale Yeast (Probably American Ale Yeast)
beginning gravity 17.3 Plato
ending gravity 4.2 Plato
bittering hops - Magnum
Finishing hops - Magnum & Crystal
dry hopping - Magnum, Crystal & Citra
malts - Two-row Pale, & Crystal
Which crystal to use and how much is really the only question. I'd guess Crystal 40, enough to get to the deep color you want, and then top off the recipe up to the desired SG with two row.
