Well for comparison, a 95 Firehawk which has an arguably better CAI with its Ram-Air set-up was rated at 300fwhp, a 25hp increase. With the optional cat-back exhaust you got another 15hp, bringing the total to 315fwhp. Typical drivetrain losses are ~15-18%, so that's roughly 260-265rwhp.
I guess it's feasible to make 18.2hp more at the flywheel with a K&N CAI. Maybe 3-5hp for the TB bypass. If you put in the cat back, maybe 15-20 hp and another 10 for the 1.6rr, so I'm guessing you'd be about 325fwhp/275rwhp with a good tune.
