this might give you a rough idea on HP/TQ: https://www.hayabusa.org/forum/gen-ii-busa-information/159542-gen-ii-busa-what-does-really-make.html
And unless you "remove" the factory top speed limiter, you can only go 186 mph (regardless of what mods you slap on it)

Sorry, only know that the guy who traded it in was meticulous about everything so infer what you can with that.
Based on one of your other threads, perhaps limit it to 8 mph? 
Just kidding. Looks like your question has been answered already!!

Looks into my magical crystal ball............ I see hmmmmmmm 186 MPH and the magical HP number if 186RWHP hope that helps you sleep tonight
Well a good thing to put on your list of things to do, is have it tuned at some point!
Stock gearing on any year gen1(17/40 gearing) that is or has been desrestricted has a potential top speed of 194mph.
Stock gearing on a derestricted gen2(18/43 gearing) has a potential top speed of 197mph.
This is what the bike is capable of, rider weight, temperature, humidity, wind, elavation, ect., all play a big part in whether or not you can actually go that fast.
A gen2 needs a 41t rear sprocket, or a 55 series rear tire with the stock 43t sprocket to be able to break 200mph.
Ballpark gains from full exhaust and filter are 10hp/5 ft lbs trq...give or take a few. Every bike and dyno are a little different.

If it's a Gen II and he doesn't weigh a bunch he might get closer to 192 with enough good road.

So what is a good gearing setup that you would recommend for a gen1 to hit the big two-double-O?
17/38, 18/40, or maybe stock 17/40 with a 55 series tire should give you the gearing to get there.
I doubt that you'll have enough motor to get their though(maybe with perfect conditions and a flyweight rider).
Pm Gotbusa? he can answer your top speed questions.
