Jus put 87 bac in it once gone.
No it won't hurt anything. Heck your motor will not know the difference. There is no more energy in that gasoline than there is in 87 octane. All the extra octane does is improve detonation resistance of the gasoline. So if you have a turbo or high compression build tuning is safer/easier. Otherwise you're just "wasting" your money.

You will get an extra 25whp???
Using a higer octane then recomended will obviously do nothing, it only matters when you have a engine that actualy calls for premium like a vtec B or K, and like metioned earlier a high comp or F.I setup.

Why would that happen?
The supposed relationship between pump gas octane and burn duration is BS. I've only seen the exact opposite.
