If aftermarket tuners can deal with the increased cylinder pressure using pump gas, it seems that a N/A motor could run on 87 octane, even with 12.5 to 1 compression. I realize that there would be a loss in power, but technically it should be able to be done, right? And yes, I realize its a sports car, and yes, I like all the power I can get, and I don't mind paying for Premium, I was just wondering if its possible, and how much power it would give up. Any tuners ever try this?

Because they wouldn't have been able to hit their power target with crap 87.
They're also realists that realize that if someone can't afford $3 per tank to get the most performance and reliability from their car, then they probably can't afford the car. I mean, really, it's such a non-issue I don't know why people are even thinking about 87.
