with low enough boost you 'could' make any forced induction work with 87 octane. however, there are many reasons why doing so would not make sense nor would it be particularly safe.
1) higher octanes prevent detonation. detonation can quickly cause severe/catastrophic engine damage. "blowing your motor"
2) if you are putting money down for a supercharger (3-6k), why would you want to settle with 87 oct when 91-93 is available at the pump and could produce 5-15 more hp?
3) most chips that come with supercharger kits are flashed for 91 oct (as california has 91 as max oct, and keeps the kit 50 state legal).
an anology would be you expanded your home and built another wing, but decided to pass on installing running water and fire alarms. if you are going to make such an investment, spend a tad more to make it safe and so you can get use out of it.
the only situation i would say running 87 oct with a s/c *might* be acceptable, is if you had virtually no funding and someone just gave you a s/c and you want to run 4-5 psi and found a chip or tuner that flashed for 87. even under those circumstances, i wouldn't do it.
